FAQ: Everything You Need to Know About Switching to E85

The subject of converting your vehicle to flex-fuel or E85 gasoline comes up a lot. Although E85 has advantages over standard E10 or non-ethanol gasoline, it also presents some disadvantages. We’ll go through the most frequently asked questions concerning switching to E85 to help identify where you will need to upgrade components for the switch.

Does E85 burn more volume than regular gasoline?

Yes. Most E85 cars require 30-40% more fuel flow compared to a regular gasoline fuel system. Using that extra volume of fuel means your fuel tank won’t last as long as before.

Does E85 have the same energy as regular gasoline?

No, E85 does not. It has approximately 26-28% less energy per gallon compared to regular E10 or non-ethanol gasoline.

What octane rating does E85 have?

Regular gasoline can be found at the pump with 87 to 94 octane available depending on where you are in the country. E85 typically has an octane value of ~104.

Is E85 gasoline cheaper than regular gas at the pump?

In most cases, E85 can be found at a lower price at the pump.

What components are required to make the switch to E85 gasoline?

Due to the extra fuel volume required, you will need at minimum a fuel pump that can pump the required extra volume, fuel injectors that can also handle the extra volume, and a re-tune of your engine management system (basically re-flash your Engine Control Module) to accommodate the larger volume of fuel.

While the minimum components will get you off on the right foot, many of us want to add more horsepower and torque to our vehicles. Beyond the fuel pump, injectors, and computer re-flash, you should add other supporting components that will flow the required fuel amount to meet your goals.

If your vehicle has a fuel pump that is rated at 100LPH (liters per hours), you may choose to replace it with a 255LPH pump instead of the minimum 155LPH pump E85 will require. You can also increase the size of the injectors equally, plus replace your fuel regulator, fuel filter, fuel lines, and fuel pump wiring for the extra required fuel flow.

Here are some of the Quantum Fuel System fuel pump options:

Part Number	Part Description	Application Notes	Horsepower Support

QFS-350FT	340LPH E85/FLEX IN-TANK EFI FUEL PUMP	Universal	640
QFS-353FT	340LPH E85 INTANK FUEL PUMP	Universal	640
QFS-450-FT	450LPH E85/FLEX IN-TANK EFI FUEL PUMP	Universal	840
QFS-606FT	380LPH INLINE EXTERNAL E85 FUEL PUMP	Universal, external mounting	716

Can any vehicle run E85 gasoline?

The complete fuel system must be prepared for E85, even though any car can run on E85 gasoline. Ethanol is corrosive to most fuel system components. The United States has incorporated 10% ethanol into gasoline since the late 1970s, but higher levels of ethanol weren’t prevalent before 2008.

Unless the fuel system components and computer system are prepared for a higher ethanol content, we should assume that any vehicle before 2008 cannot run on higher ethanol content than 10%. We recommend that you prepare each fuel system component, or at least verify that your current system can handle a higher ethanol content, before switching to E85.

Can I store my vehicle with E85 in the gas tank?

For some drivers that face extended winter cold months, they have to put their vehicles in storage. That requires preparing the fuel system to sit for a period of time. Ethanol is hygroscopic, meaning it absorbs water.

E85 is very hygroscopic, meaning it can absorb a large number of water molecules that can corrode fuel system components. You can store E85 in the fuel tank of your vehicle, but you will need to add a fuel stabilizer specifically designed for E85 to protect against its added hygroscopic properties.

Is E85 more prone to pre-ignition or detonation?

Yes, E85 is more likely to ignite before the piston reaches near the top dead center and the spark plug ignites the fuel due to the higher ethanol content. This can be compensated for with the engine management computer re-flash and potential colder spark plugs.

Does E85 Reduce Gas Mileage?

Yes, it can reduce gas mileage. E85 requires 30-40% more fuel volume compared to regular gasoline. That means you can expect your fuel mileage to be reduced by approximately the same 30-40%.

Does E85 gasoline harm catalytic converters?

No, E85 won’t harm your catalytic converters.

Is it worth it to switch to E85 gasoline?

This answer is very subjective. It can be worth the switch depending on why you are interested. The higher octane levels can be an added bonus for making more horsepower and torque, but the switch also comes with a cost for replacement parts and labor.

If you are already upgrading or building a fuel system from scratch, it may be a good option to make it all E85 compatible from the beginning. If you just want to make your vehicle E85 compatible with cheaper gas at the pump, you may find the cost of parts and labor too high to recoup the savings.

Need help switching to E85?

We continuously receive questions about switching to E85 or making a particular vehicle flex-fuel capable. The temptation of higher horsepower always lures, but you should only make the switch if you intend to incorporate changes that enable the entire system to be E85 compatible.

You should not assume that only a fuel pump, injectors, and a computer re-flash are all that is required. Double-check every component in the system before deciding to make the switch. If you have any doubts, or just need an expert to weigh in on your options, contact us at Quantum Fuel Systems.

7 Easy De-Winterizing Steps For Your Motorcycle, ATV, or Side-by-Side/UTV

7 Easy De-Winterizing Steps For Your Motorcycle, ATV, or Side-by-Side/UTV

Spring is right around the corner, and soon, the snow will melt, songbirds will chirp, and it’ll be time to take to the open road or trail again. After a long winter season where our motorcycles, ATVs, Side-by-Sides, and other Powersports vehicles sat parked in hibernation, we’ll need to do our due diligence and de-winterize them before pulling them out of cold storage and going for a ride.

If you followed our handy Winterizing 101 guide, then you’re ahead of the curve. For everyone else, we’ll cover how to get your machine running like a top in a few easy steps.

Of course, de-winterizing is made that much easier if we’ve all been astute owners and winterized our beloved toys. The reality is de-winterizing follows the same protocols that any rider or driver should take to prepare their vehicle’s roadworthiness after sitting under the covers for an extended time. You can utilize these procedures when buying pre-owned bikes or cars laid up for a while.

QFS is the undisputed leader in OE replacement fuel system parts, designed to outperform and outlast any OEM component. We stand behind our products, and a hassle-free lifetime guarantee warranty backs any QFS-branded part.

Things like fuel pumps, fuel filters, inlet strainers, fuel pressure regulators, O-rings can break down over time, especially when a vehicle isn’t being run regularly. Regardless of how well we maintain our vehicles, any fuel system needs to be inspected, cared for, and serviced. QFS offers everything you’ll need to complete the job in our massive catalog.

While this isn’t a time-consuming process, you’ll want to dedicate a few hours to complete de-winterizing like a pro.

Detective Work: Grab Some Shop Rags and Get on with the Inspections

Always start with the easy stuff. While it seems like you’ll only be spending time giving everything a spit shine, this step is one of the most crucial. Begin by pulling fairings and wiping all the critical components of your vehicle down. Keenly inspect for any trouble spots.

Over a long winter or storage period, cracks can form in rubber cooling hoses, seals could have failed, allowing fluids to weep or leak, and unnoticed wear and tear can be spotted before it becomes a potential hazard.

The tell-tale sign of a leak will be drips of fluid beneath or dribbling down various components. Take special care when wiping down, paying extra attention to suspension and engine components. Likewise, inspect your entire braking system by starting at the master cylinder and working your way down to the calipers or drums.

For anything with an advanced ABS, you might not be able to do that quickly, but run a rag over every major connection to make sure they’re fastened properly and not leaking.

Critter Check

Curious critters enjoy nesting in vehicles during the winter. So, break out a flashlight and peek into every nook and cranny. We always recommend plugging exhaust outlets when storing any vehicle, so be sure to go through and remove all those protection bits.

Sound-damping materials inside bodywork, mufflers, and airboxes serve as 5-star accommodations for any rodent. You’ll need to ensure no animals or insect colonies now call your machine home. This is a crucial step as a favorite pastime for rodents is chewing into wiring harnesses, which will cause numerous headaches down the road.

Once again, if you’ve been a diligent owner, you’ve already restricted access for our furry friends. You’ll need to reverse the process and be well on your way to your next ride or drive.

Get Charged Up

Batteries can be fickle. They don’t like being stored in the cold or sitting around unused for extended periods. This is valid for old-school lead-acid or lightweight lithium-ion types. The winter months mean you’re combining its two most minor factor activities, and the only workaround is to maintain proper voltage with a battery tender.

If you didn’t, don’t fret! Just pop it on a charger; if it’s not too far gone, it’ll be ready for action soon enough.

Fluid Levels, Lubricants, and Air Filters

It is imperative to thoroughly check and confirm that all your vehicle’s fluid and lubricants are at their proper levels. Beyond that, consider the age of coolant, engine/transmission oils, and brake fluid. Even if you haven’t achieved mileage that would warrant a change typically, refreshing these fluids yearly isn’t a bad habit. This can be done at the start of your riding season.

Brake fluid is hydroscopic and absorbs moisture, which lowers its efficacy over time. If your brake reservoir looks brown instead of a golden hue, then it’s time to refresh it.

On the same note, air filters must be regularly checked, cleaned, and reoiled to ensure they capture particulates. Once again, doing this at least once a year is a good practice, even if you haven’t racked up miles.

Cleaning and lubricating your vehicle’s chain final drive will help prevent premature rusting. Our Winterizing 101 guide explained that parking a motorcycle or ATV with a thoroughly lubricated chain will prevent rust and keep the o-rings in good health. For those that didn’t, now is the time to break out those brushes. Make that chain shine, and give it a good coat of lubricant.

The Right Rubber

Tires age naturally. While properly kept tires can last for several years, those living in icy environments will want to inspect their tires for any cracking thoroughly. In some cases, a tire can be adversely affected by freezing temperatures. The tire can become brittle and break down.

If you see any signs of cracking due to age or cold temperatures, it’s time to replace those rubbery hoops.

What’s Inside Your Tank?

When prepping your vehicle for winterization or long-term storage, you have two fuel-related choices: Drain the tank or add a fuel stabilizer. Those that choose fuel stabilizers can turn the key, start the engine, and burn through what they have available.

However, if you leave fuel in your tank for several months, it is wise to drain the tank and replace it with fresh gas. Fuel varnish and fuel separation can occur, which will cause poor engine performance or gunk up critical components.

It’s also a good idea to peek inside the fuel tank with a flashlight and inspect if your filters are in decent health. Make sure no debris has accumulated inside the tank. Remember, QFS has fuel pumps, strainers, and filters ready for nearly every make and model on the market.

Fire It Up!

Ah, you’ve checked all the fluids, oils, and lubricants or changed them. You’ve gone over every inch of your motorcycle, ATV, or Side-by-Side and made sure that everything is in working order. The battery is charged, there’s fuel in the tank, and you’re ready to go!

Once you’ve gone through this essential de-winterization checklist, it’s time to go for a decent ride or drive to get the engine up to proper operating temperature. Simply starting an engine and idling for a bit won’t do, as moisture from the air inside your engine’s crankcase will create condensation. To avoid that issue, bring your vehicle’s engine up to the full operating temperature, where it will evaporate.

Pulling a motorcycle, ATV, or Side-by-Side/UTV out of storage for the first time also requires care for both rider and machine. It’s been months since you last rode, so take things slow and get back into the swing of things. Likewise, hammering an engine immediately isn’t the best way to treat anything.

Winterizing 101: How To Prepare Your Motorcycle, ATV, or Side-by-Side/UTV for Winter

The Fall season is an incredible time to get out on your motorcycle or ATV and get behind the wheel of a Side-by-Side/UTV. The temperatures are cooling down, and we still have plenty of daylight to enjoy. But when pumpkin spice starts hitting the shelves, we know winter is just around the corner, and for many Powersports enthusiasts, it won’t be long before they’re winterizing their ride until the weather improves. Winter isn’t dreary for everyone, as that’s when the snowmobiles come out to play and more adventurous riders on dirt bikes and UTVs, too. Preparing your vehicle for winter can mean long-term storage or just the opposite.

Many riders and drivers will be bundling up to push through the colder seasons, and they’ll need to take steps to make sure their machines are ready for those potentially freezing conditions. We’ll cover the nitty-gritty of winterizing your motorcycle, ATV, Side-by-Side/UTV, or snowmobile, whether you’re hanging up your helmet for the season or getting ready to embrace the winter months.

Quantum Fuel Systems is your source for high-quality OE replacement fuel system components designed to fit your Powersports machine. All QFS-branded parts are backed by an industry-leading lifetime warranty, and our extensive catalog has direct replacement fuel pumps, fuel filters, inlet strainers, fuel pressure regulators, O-rings, and more, all built to meet or exceed OEM quality standards. Now, let’s get into winterization!

Preparing Your Vehicle For Winter: The Ins and Outs of Long-Term Storage

Depending on where you live in the country, riding or enjoying your motorcycle, ATV, or another toy can be tricky in winter. And when springtime rolls around, we all want our toys to be in tip-top shape, raring to go the moment the weather permits.

Simply parking your bike for four months straight might mean you’ll spend more time tinkering to get it on the road and missing that first ride with your buddies. These tips don’t just apply to preparing your vehicle for winter; this type of preventative maintenance should be done for any vehicle that will be stored for extended periods.

Treat Your Gas

We’ve covered the problems with ethanol fuel phase separation — from gunked-up components to rust-ridden steel fuel tanks; it’s bad news no matter how you look at it. Although it’s an easily avoidable problem and there are a few ways to handle it.

Fuel stabilizers do precisely that: Stabilize your fuel and prevent it from absorbing water, causing phase separation, and eventually ruining the fuel completely. Depending on your climate, phase separation can occur in as little as 60 days, which isn’t much time at all. Countless stabilizing options are available, and we believe that using any of them is better than doing nothing at all.

Draining the fuel tank and system avoids the spoiled gas problem altogether. When the weather clears up, you’ll have to top up your vehicle with fresh fuel from a jerrycan, but that’s a small price to pay to ensure your quad, bike, or UTV fires up immediately. Downsides include potentially drying out rubber O-rings or gaskets, and we offer high-quality replacement parts for various makes and models.

Change Your Oil and Filter

You’ll have most likely racked up the hours or miles when wrapping the riding season. Replacing your oil and filter will help prevent corrosion and remove impurities from your engine’s lubrication system. Also, you’ll be one more step ahead when Spring comes.

Clean and Lube Your Machine

Packing away your bike or UTV covered in crud will only lead to corrosion on its paint or finishes. Get in the habit of thoroughly cleaning your vehicle before parking it. Once done, inspect and lube all moving parts from the linkage to the chain, if applicable. Proper lubrication helps prevent rust buildup and extends the life of those components.

Keep Your Battery Charged

Parasitic battery drain is unavoidable, and some electrical systems draw more current than others. Worse still, your battery will naturally drain over time, and it doesn’t matter if it’s a conventional lead-acid battery or a lightweight lithium-ion variant. Ensure you use a reliable charging unit compatible with your vehicle’s battery. These days, practically everything rolling off the showroom floor is equipped with an SAE adapter, allowing owners to use a battery tender and maintain proper battery voltage. If not, either pick one up and install it, or simply remove the battery and charge it.

Pest Control: Don’t Feed Our Furry Friends

Mice, rats, and other small furry creatures will get into every nook and cranny available to them in colder months, including your precious motorcycle, quad, and car. Small rodents can begin nesting inside airboxes and exhausts while also wreaking havoc by chewing wiring. Block off areas where pests can enter, which will spare you a major headache.

Find Proper Shelter

There is no substitute for storing a vehicle indoors, but we know that isn’t a luxury for everyone. Temporarily leasing a storage unit is handy, especially for those that only have street parking available. If those options aren’t readily available, opting for a fitted cover specific to the make and model of your ride will go a long way in protecting it from the elements.

Preparing Your Vehicle for Winter Rides or Drives

Many of us don’t stop enjoying our machines when the thermometer dips and preparing your vehicle ready for winter isn’t as tricky as you might think. In fact, it comes down to using proper fluids and tires, mostly.

Tire Choice Matters

It all comes down to the terrain you plan on hitting and temperatures because those knobby off-road tires on your motorcycle, ATV, or UTV might won’t cut it in freezing conditions. You’ll want to use a softer compound tire designed to operate and sustain lower temperatures, as well as a tread pattern compatible with the terrain you’re exploring. In addition, you might need to opt for hardcore studded tires that provide grip on icy surfaces.

Lower Temps Means Lower Oil Viscosity

Lower viscosity oil flows better in frigid or freezing temperatures, which helps your engine’s lubrication system operate more effectively in harsh conditions. Running high-viscosity oil in the winter will allow cold starts to take their toll on your engine, leading to premature wear. Always reference your vehicle-specific owner’s manual and use the correct oil for your situation.

Run Anti-freeze

Those living in warmer climates can avoid using non-glycol-based coolants since their cooling systems will never risk freezing. When dealing with a true winter wonderland, you will have to increase the amount of anti-freeze in your mixture per the needs of your environment.

Choosing A Fuel Pump to Meet Horsepower Goals

October 20, 2022AUTOQuantum Fuel Systems

Choosing A Fuel Pump to Meet Horsepower Goals

If you hang around any forums or look through automotive groups on any social media platform you will often see the question, “What fuel pump do I need to make XX horsepower?” Choosing a fuel pump with horsepower goals in mind can get complex with many different answers.

We’re going to break it down to help understand what fuel pump you may need and any other considerations to keep in mind as you make plans for your fuel system.

What Fuel Pump Do I Need?

Most of the time just making a few more horsepower can be accomplished with the current fuel pump you have in your vehicle. That’s true for a Ford Mustang, Dodge Hellcat, or Chevy Camaro or Corvette. At a certain level of horsepower, the fuel pump you have won’t be able to pump enough fuel though, and that is where Quantum Fuel Systems can offer a better option.

If you look at the chart below, we have multiple fuel pumps available that can support up to 1,000 horsepower at the engine. The chart uses the standard of 2.64 horsepower per LPH (liter per hour) as the conversion criteria.

PART NUMBER	PART DESCRIPTION	HORSEPOWER SUPPORT
HFP-367	165LPH INTANK OEM REPLACEMENT FUEL PUMP	435
HFP-603	190 LPH UNIVERSAL EXTERNAL INLINE PUMP	501
HFP-342	255LPH PERFORMANCE INTANK FUEL PUMP	673
QFS-342FT	340LPH E85/FLEX IN-TANK EFI PERFORMANCE FUEL PUMP	897
QFS-343FT	340LPH E85 INTANK FUEL PUMP	897
QFS-606FT	380LPH INLINE EXTERNAL E85 COMPATIBLE FUEL PUMP	1000

Keep in mind that adding a larger fuel pump may require modification of your housing to clear a larger fuel pump. This could include creating windows in the assembly housing, or enlarging current windows or recesses currently in there.

Other considerations when adding a larger fuel pump:

What fuel will you be using?

Most upgrades are to flow standard or high-octane gasoline (such as E10 or E15 depending on your location). If you plan to move to a flex-fuel system that can handle E85, or make the switch to E85 primarily, you may need to account for the additional 40% volume required for fuel systems using E85. That will indicate you should purchase a fuel pump one or two sizes larger than you need for standard gasoline.

Can your current fuel tank enclose a larger fuel pump internally, or will the new system require an externally mounted pump?

Moving from an internal pump to an external pump may require a different inlet strainer and pre-filter to keep contaminants out of the new fuel pump. You may also need a new mounting system (such as insulated fuel pump mounting brackets) for an externally mounted pump.

Will your other fuel components handle the additional volume you plan to pump?

Are your fuel lines large enough to support 600 horsepower, 700, 800, etc.? Do you need a larger pre-filter or fuel filter for extra volume? Lastly, what size and type of fuel injectors are needed to meet your horsepower goals?

Would adding an external fuel pressure gauge be advantageous for tuning your new system or trouble-shooting future upgrades?

A gauge can be an easy addition while you complete the other work, and it can add some comfort in being able to see how your system is performing initially and months or years later.

The last thing to consider would be the minor details for a clean upgrade. Do you need an installation kit complete with electrical connectors, hose clamps, and protective sleeves?

QFS Is Here To Help

Looking through all of this information, it’s easy to feel overwhelmed when trying to add a few more horsepower. Some pumps are designed to drop in your current internally mounted tank and be ready to go within a few hours.

In other cases, you may need injectors, fuel lines, and some extra accessories to support the horsepower goal. Whichever situation you have, there’s no need to stress over what pieces and pumps you need.

You can order a better-designed replacement pump or complete assembly from Quantum Fuel Systems, Monday through Friday, 8:00 a.m. to 5:00 p.m. PT, over the phone or browse our extensive catalog.

Revive Your GM 1500 Series With An Upgraded Fuel Pump

October 6, 2022AUTOQuantum Fuel Systems

REVIVE YOUR GM 1500 SERIES WITH AN UPGRADED FUEL PUMP

Trucks have been a great starting place for restoration and modification projects. Many automotive brands have offered models over the last 70 years with differing chassis, engine, and drive combinations. If you’re looking for a low-cost option with a healthy aftermarket and restoration availability, you may find the 1997 – 2003 General Motors 1500 series trucks to be a perfect fit for your needs. During restoration, it’s incredibly important to consider replacing or upgrading your GM 1500 Series fuel pump.

Choosing the Low-Cost Budget Truck

Both Chevrolet and GMC half-ton truck lines have multiple trim levels available, different engine and transmission options, and come available in both 2WD and 4WD. There is something for everyone.

This model featured the LS-engine family that started a new revolution that saw these engines swapped into everything. Most restoration projects will choose the V8 models or swap one of them in though.

The 4.8-liter V8 (producing 255 horsepower and 285 pound-feet of torque), the 5.3-liter V8 (producing 270 horsepower and 315 pound-feet of torque), and the 6.0-liter V8 (producing 300 horsepower and 355 pound-feet of torque) were available as options from General Motors, and all three have immense potential for restoration or modification.

Assuming the truck runs and drives, one area of focus should be the fuel system. The truck could have sat at some point in its life, or it could have been a constant workhorse and now have a few hundred thousand miles on the odometer.

Whatever the case may be, the fuel pump and other fuel system components may be on their last legs. If you have concerns with either, now is the time to address them. A new fuel system is key for the next phase of the truck’s life.

https://blog.highflowfuel.com/how-to-diagnose-a-bad-fuel_pump/

Replacing the 1999 – 2003 Chevy & GMC 1500 Series Fuel Pump Assembly

Replacing the fuel pump or the complete fuel pump assembly on the 1500 series trucks isn’t a complicated process. Once the fuel tank is removed from the vehicle, the fuel pump assembly can be taken out from the top side of the tank with simple hand tools.

Some will simply replace the pump assembly with an OEM drop-in replacement, however, keeping the factory design will keep inherent design problems going forward. The factory design uses a problematic venturi design to keep the canister full during hard cornering.

If you plan to build a corner carving truck for autocross, keeping this design will have limitations. The venturi design was used in all 1995 – 2005 GM trucks, vans, and SUVs, which will only allow for OEM-style fuel pumps with limited fuel flow potential.

Combating OEM Design Limitations

If you plan to add more horsepower to your truck, the OEM fuel pump won’t flow enough fuel for a lot more power than the factory level. You can add a larger fuel pump for more flow. Doing so requires the fuel pump assembly to be modified by cutting windows into the sides of the bucket.

This completely disables the venturi function of the OEM housing and the ability of the canister to stay full during cornering or acceleration. It will eventually lead to fuel starvation and overheating of the fuel pump.

Fixing the poor venturi design and adding a larger fuel pump can be achieved by switching over to Quantum’s QFS-A81HV 340LPH (340 liters per hour) drop-in fuel pump assembly. This assembly was designed specifically for the 1999 – 2003 Chevy and GMC 1500 Series trucks to eliminate the problematic venturi canister design found in all 1995 – 2005 GM trucks, vans, and SUVs while offering significantly more fuel flow for larger engines or forced induction applications.

This clean sheet design also allows the fuel tank to be run down to empty as the OEM fuel assembly does.

The assembly uses Ethanol safe PTFE / Teflon corrugated flex hose and Teflon-coated wiring throughout. They are 100% gasoline and E85 compatible. The new design features an updated 40-amp bulkhead connector to handle the additional amperage load of the high-volume pump, plus includes a new float arm, sending unit, tank seal, and 4-way wiring connector.

All QFS products come with a lifetime warranty. There’s no need to worry about paying for a replacement later.

Replacing Just The Fuel Pump

If you aren’t ready for a new complete assembly, you may just need to change the fuel pump only. A previous owner may have replaced or upgraded the assembly. In this case, you just need to add a new pump to meet your goals.

That’s an easy fix with Quantum’s varying selection of performance fuel pumps. Each pump in the line-up offers a different fuel flow to meet your horsepower goals. Check out the chart below to see which pump is rated at the horsepower level you need.

The chart uses the standard of 2.64 horsepower per LPH as the conversion criteria.

We Are Standing By For Your Order

If you plan to build or simply restore a 1999 – 2003 Chevy or GMC 1500 series truck, take the time to get the fuel system up to snuff. It’s most likely 20 years old, and if it was a previous work truck, it may not have been well maintained. The OEM design works well for simple replacement, but if you plan to modify your truck it will need a better fuel system.

We get out on the trail as much as we can. We want to help anyone getting into the hobby so we’ve compiled a list of resources for anyone planning to off-road while using their ATV, motorcycle, UTV/Side-by-Side, or four-wheel-drive vehicles.

From family-friendly Jeep trails to black diamond-rated routes, the resources listed here give you access to information listing legal off-road trail systems throughout the United States and outside the continental U.S. in some cases. Bookmark this page and download these apps while you gear up for your next off-road excursion.

QFS specializes in direct OE-replacement components for a wide selection of Powersports and automotive applications. Be sure to check out our extensive catalog before hitting the wilderness. Stocking up on dependable fuel pumps and fuel system components could save your trip.

Off-Road Trail Resources — Websites

The United States Forest Service:

The U.S. Forest Service is an invaluable resource for anyone planning their next off-road trip that lives near or plans on passing through a national park. Off-roaders can find a comprehensive list of Off-highway vehicle (OHV) routes and recreation areas in every national park across the country.

In addition, there is plenty of important information regarding camping, camping restrictions, road conditions, closures, and weather or general hazard warnings. Other apps and services may offer the same information, but these are the people providing that information to the public regarding national parks.

Beyond that, the U.S. Forest Service website provides detailed outlines as to what vehicles are suitable on any given trails. Some OHV parks and certain trail systems may have specific regulations that need to be followed, all of which will be stipulated here.

In addition, the USFS is responsible for maintaining these routes and provides contact information for district offices, where you can speak with USFS Rangers, who often have up-to-date information available. We strongly encourage readers to take down relevant field office phone numbers in an emergency.

Bureau of Land Management:

The Bureau of Land Management and the U.S. Forest Service serve similar functions in that both agencies manage public lands, keeping them maintained and suitable for multiple uses. Their websites offer helpful information, including a database of all OHV recreation areas and trails managed by the BLM.

Camping information, including amenities, restrictions, pricing, and more, is readily available for those interested. Not unlike the U.S. Forest Service website, all this information is free and constantly updated. Once again, contact local field offices for the most up-to-date information. BLM staff have a wealth of knowledge regarding the areas they serve, including closures and poor trail conditions.

Off-Road Trail Resources — Apps

AllTrails

AllTrails is available on Android and iOS and is one of the best free resources for route planning available today. We should note that there is a $29.99 Pro service plan, but the free account is more than enough to plan a route and search for trails by location. Pro does unlock helpful features such as downloadable maps and offline access, lifeline features to alert your whereabouts, an off-route alert system, and real-time map overlaps with (air quality, weather, light, and more).

Many readers may associate AllTrails with outdoor activities such as hiking, backpacking, or bicycling. However, users can search for OHV trails specifically. Even more helpful is the detailed user-generated information such as reviews, difficulty ratings, trail length, time estimates, and photos.

This information is invaluable as popular, regularly trafficked trails receive regular updates and can provide quality insight regarding your upcoming journey. Trust us; nothing is worse than hitting a path you and your vehicle aren’t entirely ready to manage.

Gaia GPS

Gaia GPS has quickly taken over the off-road scene. It has become especially popular with 4-wheel-drive owners and even more so with ADV, dual-sport, and enduro motorcyclists since it has comparable functionality to standalone GPS units.

Much like AllTrails, Gaia has a thriving community and user-generated trail data. You can isolate off-road tails, ensuring that you aren’t taken down standard hiking routes. Difficulty ratings and mileage are reference, too.

As with many GPS apps, these are multifunctional tools that allow users to always remain on legal trails, providing accurate campsite, park, and forest locations in conjunction with weather overlays. Gaia is no different in that regard.

ADD TO CART

Gaia has grown in popularity within the off-roading community because it allows users to create custom waypoints and develop off-roading routes. There are also detailed layers of information providing elevation, grade, and much more. Users can also import premade GPX files, which are often distributed for rallies and other off-road events. Lastly, Gaia GPS supports Apple CarPlay and Android Auto, seamlessly integrating with a modern dashboard.

Premium Membership is $19.99 per year and unlocks numerous features that hardcore off-roaders deem worthy. Some of the best features include mass-download maps for offline use and access to the worldwide map database. That database includes: ESRI World Satellite Imagery, NOAA weather forecasts, U.S. Private Land Ownership (including owner names and addresses for parcels), US Hunting Layers, U.S. Public Land (BLM, Forests, more), and most importantly, U.S. Motor Vehicle Use Maps (MVUMs), and more.

The main downside of using your mobile device instead of a standalone GPS unit is that they are not as pinpoint accurate. However, they’re unlikely to get you off course and unless you need absolute precision in your route tracking, using your smartphone is more than adequate.

Gaia GPS is available on Android and iOS.

OnX Offroad

OnX Offroad is one of the few apps designed for offroad navigation specifically. Unfortunately, it is the only app on this list that doesn’t have a free membership. The yearly service fee is $29.99.

The upshot is that OnX Offroad is geared toward anyone looking for off-road trails and prevents users from accidentally combining non-off-road trails into their lists . It does not list standard trails. OnX Offroad boasts a massive database with 985 million acres of public land and over 550,000 miles of roads and trails, with specific information such as open dates and width restrictions. 4WD owners will appreciate that.

Reference countless topographic and satellite maps to create routes and custom waypoints that can be shared with friends in your group. More importantly, what sets it apart from other mapping apps is that it caters to the off-road community in more ways than one.

The map interface allows users to filter trails and display routes into specific categories. Categories include: Dirt bike trails, 50-inch trails (dirt bikes and ATVs), high-clearance 4×4 trails (Jeeps, Side-by-Sies, ATVs, motorcycles), and full-width roads. Again, no other app in this article accommodates those features, giving you unparalleled route planning knowledge. Need to create a loop and keep it dirt bikes only? You can do that. Want to make sure that your ATV or Side-by-Side buddies can join in? Well, you can map that out as well.

Lastly, OnX Offroad supports Android Auto and Apple CarPlay.

OnX Offroad is available on Android and iOS.

First Bike Choices: Start Small and Think Big

One of the most common mistakes new riders make is failing to pick an appropriate starter bike. In many cases, beginner riders will choose a motorcycle that’s too powerful, too big, and too intimidating. This only hinders your ability to develop foundational skills and thrive over your riding career.

The logic behind starting with a bigger dirt bike is that a rider can “grow into it”. While that strategy has worked for some people, in most cases, it simply makes getting into off-road riding challenging.

Learning fundamental skills such as throttle, clutch, and brake control is exponentially more difficult on machines designed for experienced riders. Typically, that means larger-displacement motorcycles that boast higher engine performance, weight, and price tags.

We suggest new riders “start small and think big.” A low-displacement dirt bike will often have a lower seat height, allowing an easier reach to the ground, offering welcoming engine performance, and have a reasonable introductory cost.

Taller teens and adults should avoid getting anything above a 300cc trail bike as their first off-road motorcycle. If we’re talking about motocross specifically, then lighter riders shouldn’t go above 125cc while adults can most likely begin on a 250cc MX bike due to their size.

Shorter and younger riders should consider 110cc, 140cc, and 230cc options as they’re all aimed directly at new riders. Meanwhile, kids have a wealth of options starting as low as 50cc. Visit a reputable local dealer and try things on for size before putting your cash down.

Gear Up

Wearing proper safety equipment is the difference between brushing off a hard hit and visiting the hospital. Whether you’re riding motocross, trails, or dual sport, we recommend investing in high-quality U.S. DOT-approved helmets, durable goggles, armor, knee braces, boots, and riding apparel.

High-end riding equipment can be cost-prohibitive, especially for new riders just getting their feet wet in the sport. Beginner armor sets, riding pants, and jerseys will save riders quite a bit, but no one should skimp on helmets or boots. Buy the highest-quality and safest options within your budget.

Clutch and Throttle Control

Mastering the clutch and throttle is crucial for any rider as we constantly manipulate them while riding. It all comes down to timing and understanding when to disengage the clutch, roll the throttle on or off, shift through the gears, or blend the clutch and throttle simultaneously.

Practice makes perfect, and it’s best to take things slow with any new skill or motorcycle. Start by sitting on the motorcycle while it’s not running and become familiar with all its controls. Where are the front and rear brakes? Where are the clutch and shift levers? Locate the start button (or kick starter) and kill switch. Then familiarize yourself with the shift pattern — 1, N, 2, 3, 4, 5 is a typical transmission layout, though yours may differ.

Get your bike ready to roll and fire up the engine with the transmission in neutral. Pull in the clutch lever and press down into first gear. Slowly release the clutch lever until you feel the engagement point. This is also called the friction zone, where the clutch begins engaging, and power is transferred to the rear wheel.

Feed the clutch lever out until the motorcycle rolls forward under its power and paddle along with your feet. Pull in the clutch again after a few feet. Repeat that a handful of times before adding throttle to help initiate your start. A small amount of throttle can go a long way. Always remember to make your inputs as smooth and progressive as possible. As you begin rolling, completely release the clutch lever and use the throttle to slowly accelerate, selecting the next gear as you feel the engine wind out.

It won’t take long before you add more throttle and explore by shifting up and down through the gearbox. Always use the clutch when selecting a different gear. This approach helps prolong the life of your transmission and clutch when not using advanced clutch-less shifting techniques.

Body Positioning

There’s much more to riding a dirt bike than simply sitting on it, and the pros make it look easy. Experienced riders constantly move in the saddle, shifting their weight when accelerating, cornering, jumping, or stopping.

You’ll see riders often standing or sitting at any given time and we know what you’re about to ask, “when do I stand or sit on a dirt bike?” Well, the answer is that it depends. Speaking broadly, standing can help when riding on rocky, bumpy, or fast terrain. Sitting down conserves energy, and you’ll want to use that when on relatively flat roads, but it can be useful when cornering and negotiating slow, technical sections.

We call standing while riding the “attack position,” and it will feel awkward at first: Keep practicing and building stamina because standing offers the most feedback and control when riding off-road. There are several benefits from riding like this, but chief among them is the ability to keep your weight centered on the bike, adjust your weight to different areas of the motorcycle quickly, and above all else, use your legs to help absorb hits.

Get into the attack position by standing on the balls of your feet, knees slightly bent and gently squeezing the seat for stabilization, elbows held high, and your head over your handlebars. Riding tense will make you fight the bike’s movement and tire you out quickly. Above all, you must stay loose and let the motorcycle move freely.

In extremely slippery, technical, and slow-going terrain, riders may sit and “paddle” with their legs because they’re not moving fast enough to balance correctly. Sitting is useful as well and lets us relax, which is important on long rides. But it is also useful when cornering or loading the rear wheel for additional grip while accelerating.

Cornering

Cornering is all about weight distribution and helping the motorcycle generate grip. There are a few steadfast rules with turning, even if the techniques might vary from each type of corner, such as flat turns, berms, or rutted corners. Always be smooth with your braking and throttle inputs, and most importantly, load the outside footpeg.

ADD TO CART

In most cases, we want our weight forward towards the fuel tank. This creates better traction and get the bike to turn. Off-road riding usually doesn’t allow you to lean with the motorcycle unless you’re using a berm or rut in a corner.

Riders will use their core strength to sit upright as the bike leans left or right. As we initiate the turn, it’s crucial to distribute your body weight through the outside footpeg with your outer elbow held high. If you’re turning right, the bike will lean right, while you sit upright and with half your butt on the left side of the seat.

Also, make sure that you lift your inside leg towards the front mudguard to keep your boot from catching the ground. Not only does this bias more weight towards the front wheel, but it reduces the chance of catching your boot and causing an injury.

Berms and rutted turns have positive camber and allow you to lean with the bike, sitting in the center of the seat. Everything else still applies, and true beginners won’t be hard-charging berms or rutted corners yet.

Vision

You go where you look when riding motorcycles. Even veteran riders need remind themselves to look far down the trail or track.

Always scan back and forth, far beyond the front fender, since you’ll be able to identify and anticipate obstacles ahead. It’s easy to get fatigued and drop our eyes when riding, leading to severe problems as the pace picks up.

Braking

Your brakes are potent, especially when using knobby tires that dig into the dirt, creating loads of traction. Your front brake will provide far more stopping force than the rear, but they are equally important and must be used strategically.

Newer riders should never forget to be smooth and progressive with their braking inputs. Jamming on the brakes will break traction, lock the wheel, and cause a tumble. Progressively loading the levers will allow the suspension to compress and the tires to bite confidently.

Become familiar with braking by practicing at low speeds, applying each brake independently, and learning when the wheels will lock up. Different surfaces provide different levels of grip. Slightly damp dirt offers far more braking potential and traction than mud and your braking pressure will need to be adjusted. Practice using the brakes simultaneously and learning to modulate pressure.

Practice, Practice, Practice

It doesn’t matter what discipline you happen to do, trail riding, enduro, motocross — it all takes practice and dedication. The good news is that even our favorite pros had to start at the same place with practicing the basics. So, get geared up and start honing your skills with some of these beginner dirt bike riding tips!

Motorcycle Types Explained

The motorcycle landscape is constantly evolving. There are makes and models for every type of riding and rider these days. Wind the clock back a few decades, and that wasn’t the case. Seeing as we now have a cornucopia of motorcycle types packing dealership floors.

Whether you’re thinking about kickstarting your riding career or are a salty veteran with the bugs on your visor or goggles to prove it, we’ll break down the most common motorcycle categories available today to keep you informed.

Motorcycle Types

Adventure (ADV)

Adventure motorcycles are built as rugged as they look and not stop when the pavement ends — hence the name, Adventure or ADV.

ADV bikes are the motorcycling equivalent to a modern SUV. They can hit any terrain thanks to their long-travel suspension, increased ground clearance, and larger wheel sizes.

Meanwhile, aspects like their great comfort and excellent wind protection make them wonderful choices for long-distance riding. You can always spot an ADV motorcycle because it will look like a dirt bike that’s hit the gym.

Adventure bikes can ride off-road, but that isn’t their primary purpose. The more expensive, heavier, and larger-displacement ADV motorcycles can become challenging to pilot in the dirt because of their weight and size.

These motorcycle types are all-around machines but do incredibly well on the road. Many owners never venture into the trails, enjoying good comfort and massive fuel range. Another benefit is that Adventure motorcycles can accommodate luggage and a passenger easily, making them even more appealing for travel.

The ADV segment has grown over the years with offerings that come in all shapes and sizes, ranging from lower-displacement and more affordable models fit for beginners to pricier, high-performance, and technologically advanced offerings for more experienced motorcyclists.

If you need a bike that can go long distances and do some light off-road riding, an Adventure (ADV) bike is a great option.

Café Racer

Café racers date back to London in the 1960s and are a staple in the British motorcycling scene, inspired by professional racing motorcycles of the past. Back then, motorcycle manufacturers didn’t create sportbikes with low clip-on handlebars and aggressive seating positions from the factory.

If you wanted that look and riding style, you had to do it yourself. Riders would take standard motorcycles, strip unnecessary parts, and create race-oriented seating positions suitable for faster riding. The trend still thrives to this day, and since then, many motorcycle makers now offer production café racers capturing that classic style.

Whether it’s a custom build or production model, café racers are all about looking cool, and there are some fine examples available today. Due to the race-inspired riding position, these motorcycles can become uncomfortable over long distances and are not recommended for newer riders.

Cruiser

**Harley-Davidson Sportster Forty-Eight**

Cruisers do precisely what their name says: Cruise. These long, low motorcycles have a seating position that lets you lean back to enjoy the scenery.

Moreover, cruisers often use a V-twin engine that focuses on delivering most of its power right off the line. In the United States, brands like Harley-Davidson and Indian Motorcycle dominate the cruiser conversation.

Cruisers appeal to newer riders because of their often incredibly low seat and stand-over heights, which help boost those with less experience. In addition, these motorcycle types have a low center of gravity that makes them easier to control.

Lastly, V-twin engines are all about torque and provide useable power much early, which newer riders find reassuring.

Dual Sport

Dual sport motorcycles are little more than street-legal dirt bikes: Lights, license plates, turn indicators, and emissions equipment is there, but at its core, it’s a dirt bike. Dual sport models are lightweight bikes with long-travel suspension capable of performing off-road riding.

Street-oriented dual-sport machines typically have shorter suspension travel and seat heights, which are great characteristics for riders new to motorcycling. More extreme models are aimed at competition, utilizing additional suspension travel, taller seat heights, and off-road-oriented components.

Dual sports from KTM, Husqvarna, Beta, and Sherco fall in the performance category. Dual sport bikes are some of the few motorcycles where you can leave your garage in the morning, ride the trails all day, and come home on the same roads in the evening.

Those that live close to OHV parks and authorized trails should investigate a dual sport bike.

Naked

Naked bikes are simply motorcycles without fairings, exposing much of the engine and chassis for all to see. In a modern context, naked bikes are derivatives of proper full-fairing sportbikes, offering similar performance and handling characteristics.

However, naked bikes are much more suitable for everyday street riding since they use an upright riding position. They’re also sometimes referred to as streetfighters.

These motorcycle types are on the sporting side of the spectrum and is available in various engine displacements. Options perfect for beginner, intermediate, and advanced riders are common from nearly all manufacturers and is currently one of the most popular categories.

Everyday commutes, sport riding, traveling, and even racetrack riding can be done on these motorcycles, depending on the model and its positioning.

Standard

Simple and to-the-point two-wheeled transportation. A standard is your classic motorcycle: A bench seat, handlebars, and usually a steel-cradle frame. This segment is vast and includes any motorcycle without fairings for wind protection and a neutral riding position.

Technically, many naked bikes would fit into this class by that description, but standards do not have a performance slant.

These bikes are great for just about anyone getting into riding and are impressively maneuverable, which makes them exceptional in urban environments. A good standard motorcycle can do a little bit of everything and are suitable for riders with any skill level.

Sportbike

Sportbikes are the pinnacle of motorcycle technology, flexing the highest performance, most advanced rider aids, and aerodynamic features. For that reason, many sportbikes are the flagship models within a manufacturer’s lineup.

These motorcycles are often referred to as “race replicas” because they are a street-legal version of what’s used in professional racing.

These high-performance motorcycles are best experienced when ridden aggressively at a racetrack, where the stiff suspension and uncompromising riding position can be put to good use. In a street environment, that demanding riding position can lead to cramping in your legs and wrists when stuck at lower road speeds.

There are two major classes of sportbikes: 600cc or equivalent Supersports and Superbikes that can exceed 1000cc engine displacements. These bikes are intended for experienced riders only.

However, there are also lightweight 300cc and 400cc sportbikes that are perfect for newer riders, thanks to comfortable riding positions and manageable engine performance.

Touring

Touring motorcycles offer every comfort amenity imaginable: Heated grips, heated seats, wind protection, and infotainment systems designed specifically for touring the country.

Better yet, that all applies to your passenger, too. Racking up hundreds of miles in a single day is easy work on a comfortable touring motorcycle, which also typically features ample storage space for extended trips.

ADD TO CART

Touring machines come in various styles, yet storage and comfort are consistent traits. In addition, various engine configurations are found in this class, with V-twin, inline-three-cylinder, inline-four-cylinder, and inline-six-cylinder engines used with great success.

Anything in the touring segment will be big, comfortable, and feature-loaded to keep you happy while riding from state to state. These motorcycle types aren’t popular with younger audiences mainly due to their higher MSRPs, typically attracting older and financially secure buyers.

Sport Tourer

What happens when you splice the DNA of a Sportbike and a Touring motorcycle? You get a Sport Tourer.

The creature comforts of a massive luxury touring machine built into a far lighter and sportier motorcycle simply means you can ride much faster through the curves when the opportunity arises.

Sport Touring motorcycles often offer many practical benefits of touring bikes, such as storage, ample wind protection, and heated seats or grips. Still, they allow riders to enjoy a motorcycle that’s quite capable in the corners.

These motorcycles types are always user-friendly and easy to ride, appealing to various skill levels.

Motocross

Motocross motorcycles are designed for racing and are meant to be ridden at motocross tracks. Not unlike sportbikes, these machines are engineered for peak off-road performance with massively tall seat heights and powerful single-cylinder engines to match.

The suspension travel is some of the longest in the two-wheeled world, which is needed for soaking up landings when clearing jumps. As uncompromising as motocross sounds, motocross is a segment that offers suitable models for all skill levels and kids as low as 4-years old.

Trail Bikes

A motocross, dual-sport, and trail bike look similar to the untrained eye. However, each of those categories has an intended purpose. Trail bikes are incredibly friendly with accommodating seat heights and engine performance that many riders will find agreeable.

These off-road motorcycles are equipped for less intense riding than motocross and are excellent for casual off-road riding.

It is vital to remember that trail bikes are not street legal, despite sometimes being equipped with lighting. In addition, their use may be seasonally restricted, depending on where you live in the country.

Scooter

We all know what a scooter is! Scooters are some of the most user-friendly vehicles on the road and typically shift automatically — just twist the grip and off you go. They’re perfect for congested cities where short commutes are common and offer under-seat storage compartments.

In many ways, scooters are the perfect motorcycle types for young people that need economical transportation. In the United States, scooters are classified as motorcycles, meaning that you need a motorcycle endorsement to operate one legally.

How Ethanol Fuels Impact Your Fuel Pump and Fuel System

How Ethanol Fuels Impact Your Fuel Pump and Fuel System

Ethanol-blended fuels are the dominant force in America’s fuel supply. While most modern vehicles are specifically engineered to handle these fuel blends, many cars, trucks, motorcycles, ATVs, and UTVs can run into problems when using certain ethanol-fuel combinations. The greater concern is that ethanol is harder on fuel pumps and other fuel system components. In some instances, rubber expansion, plastic degradation, and metal corrosion may occur.

According to the U.S. Department of Energy, more than 98% of gasoline sold in the United States contains ethanol, which is what we likely buy at the pump.

We will examine why ethanol-based fuels can cause harm to your fuel pump and fuel system and what to look for when purchasing replacement components. But, before we dig into the impact that ethanol fuels have on your parts, let’s understand why they’re used, the pros and cons, and what vehicles can use E10, E15, and E85 ethanol-gasoline blends.

Quantum Fuel Systems is an industry leader in high-quality OE replacement and performance fuel system components. All QFS products are designed to exceed OEM requirements while utilizing top-tier ethanol-fuel-safe plastic, rubber, and corrosion-resistant materials.

Whether we’re talking two-wheels, four, or marine applications, our catalog has everything to cover your fuel system needs.

WHAT IS ETHANOL

WHY USE ETHANOL

E10, E15 & E85

PROBLEMS WITH ETHANOL

PREVENTING PROBLEMS

What Is Ethanol?

Ethanol, otherwise known as ethyl alcohol, is a biofuel addictive created by fermenting biological matter. If that sounds like your average alcoholic beverage, that’s because it is the same type of alcohol found in most beer, liquor, and wine.

However, ethanol is denatured alcohol and has poisonous additives making it unfit for human consumption.

The process begins by fermenting sugars found in grain starches, such as corn, sorghum, and barley, or other sources like sugar cane and sugar beets. Ethanol production isn’t limited to these sources alone and can be manufactured using other plant materials like grasses, wood, or algae.

These renewable organic materials are called biomass, hence why ethanol-blended fuels are referred to as biofuels. In the United States, most fuel ethanol is produced by fermenting corn.

Why Use Ethanol Fuels?

The reasoning behind using ethanol-blended fuel weaves complicated economic, geopolitical, and environmental issues together. Ethanol is a renewable energy source derived from domestically produced plant materials and, when mixed with gasoline, can help reduce America’s dependence on foreign oil imports.

There are additional environmental benefits as well.

Ethanol is an oxygenate that enhances fuel combustion, producing lower carbon monoxide and pollution emissions. With that much supporting ethanol, it’s safe to say that ethanol is here to stay, and we’ll need to learn to work with it.

E10, E15, and E85 Explained

Three primary ethanol-gasoline blends are sold in the United States: E10, E15, and E85. E10 is gasoline containing 10% ethanol, E15 contains 15% ethanol, and E85 uses a variable 51-83% ethanol blend, depending on the region and season.

Ethanol and Octane

This is where there is some confusion for consumers: The number values next to “E” do not relate to octane. E10 and E15 blends are used to create the 87-95 octane fuels commonly available at gas stations.

Meanwhile, E85 often exceeds 100 octane depending on the ethanol-gasoline. The significantly higher ethanol content and octane of E85 can only be used with engines specifically designed to accommodate it.

Interestingly, ethanol has higher octane than gasoline. However, ethanol is roughly 33% less energy dense than pure gasoline.

That means ethanol can produce more horsepower but is less efficient than gasoline when burned. Less efficiency results in slightly reduced gas mileage when using ethanol-blended fuels.

Vehicle Compatibility

E10 has been sold across the United States for years and is deemed safe for all modern cars, trucks, and Powersports vehicles. While true in most cases, there are some complications related to ethanol that we’ll examine later.

Additionally, we recommend referencing your vehicle-specific owner’s manual to confirm the suitable fuel type and grade.

E15 can be used safely in vehicles manufactured in 2001 and after, according to the Environmental Protection Agency. Importantly, we should note motorcycles, ATVs, UTVs/Side-by-Sides, and marine engines are rarely designed to accept E15 fuel and should not be used.

E85, also known as Flex Fuel, is a high-volume ethanol blend that can only be used in engines designed explicitly for Flexible Fuel Vehicles (FFVs). FFVs are designed to use other fuel grades, but E85 often features high-octane ratings, requiring engineering to compensate for those needs.

ADD TO CART

Despite E85 being marketed as an environmental-friendly fuel alternative, E85 is popular among tuners and performance-engine builders for various reasons. Compared to gasoline and lower ethanol blends, E85 features high oxygen content, better evaporative cooling, greater knock resistance, lower exhaust gas temperatures, and much higher octane.

Those running high-performance engine components can gain extra horsepower by using E85 and adjusting fueling or ECU maps to utilize it properly. In addition to that, you must ensure that your vehicle’s fuel pump and fuel system components are ethanol safe.

QFS offers everything you need to make your performance build E85 ready.

Ethanol Gasoline

Most problems with ethanol stem from the fact that it is hydroscopic, meaning it absorbs water from the air. Gasoline is hydrophobic and repels water.

Ethanol and gasoline can mix, but if the water concentration becomes too high, then phase separation will occur. The ethanol and water will separate from the gasoline and settle at the bottom of the storage tank.

Leaving metal components submerged in water will cause corrosion and damage parts like an in-tank fuel pump, fuel sending unit, strainer, filter, or regulator.

Worse yet, the ethanol and water mixture becomes a perfect breeding ground for an acetic bacteria known as acetobacter. Acetobacter causes the mixture to become highly acidic. This destructive environment can quickly wreak havoc on components throughout your fuel system.

Vintage and late model vehicles are more susceptible to ethanol fuel issues because manufacturers didn’t anticipate engineering plastics, rubbers, and metals to withstand the corrosive environments ethanol fuels can create. While ethanol has been used as an additive dating back over 100 year, it didn’t gain prominence until recently.

Those who own vehicles with older-style metal fuel tanks will want to take special care when using ethanol gasoline. Older rubber components like O-rings, gaskets, and fuel lines can swell or become brittle and break down. Damaged components lead to numerous mechanical failures.

OEMs have since transitioned to ethanol-fuel-safe components to avoid these problems. Reputable aftermarket manufacturers like QFS use ethanol-compliant components in all fuel system parts, ensuring that your vehicle will run trouble-free on ethanol fuel blends.

Preventing Ethanol Fuel Problems & Ethanol Phase Separation Treatment

Ethanol fuels have a lousy reputation among gearheads, especially those running vintage vehicles. Most problems associated with ethanol-blended fuel can be avoided through some simple strategies.

Phase separation only occurs when a vehicle is stationary for a prolonged period. Most ethanol fuels will experience phase separation in roughly 60 days in a high-temperature and high-heat environment. The easiest solution is to operate your vehicle and cycle fuel through the system to prevent phase separation.

If you store your vehicle for extended periods, treat the fuel with stabilizers or fill it up using non-ethanol fuels. These fuel types can still be found at some specialty gas stations.

5 Ways To Maintain Your Fuel System

Outdoor recreation is booming, which means more people are using their Powersports vehicles. Motorcycles, dirt bikes, ATVs, UTVs/Side-By-Sides, snowmobiles, and personal watercraft are racking up hours across the United States as new riders and families join in on the fun. Motorcycle sales alone were up nearly 10 percent in 2021, hitting their highest levels in 15 years. We’re going to go over five easy ways to maintain your fuel system and ensure it’s in good working order, giving you peak performance, fuel mileage, and reliability.

All that time out on the road, trail, or water does add up, and responsible owners know that to get the most out of our vehicles, they need to keep up with regular maintenance. Even the most diligent owners and DIY mechanics overlook their fuel systems until there is a problem.

Don’t think these tips are exclusive to your motorcycle, quad, or UTV — these maintenance suggestions apply to any car, truck, or RV equipped with Electronic Fuel Injection (EFI). These tips are to help prevent fuel pump failure, regardless of vehicle type.

Quantum Fuel Systems (QFS) is the authority in high-quality direct OE replacement fuel system components. All QFS-branded parts are backed by an industry-leading lifetime warranty and are designed to meet or exceed OEM quality. Visit our catalog for all your fuel system needs when maintaining or repairing your fuel pump or fuel system.

1. Keep Your Fuel Tank Full

This is one of the most straightforward tips of the bunch and applies to any standard in-tank fuel pump conveniently located inside your fuel tank. In-tank fuel pumps are constantly submerged in liquid fuel, helping lubricate and cool one of the hardest working components in your fuel system.

Radiant heat from the engine and the fuel pump’s electric motor will increase fuel temperature as your fuel load drops, putting more stress on the fuel pump and causing it to work harder, leading to premature failure.

While today’s gas prices certainly aren’t making things easy for consumers, one of the simplest ways to maintain the health of your fuel pump is never run on empty. Always try to stay above ¼, and your fuel pump will thank you for it.

2. Don’t Fill Up When The Fuel Delivery Truck Is At The Gas Station

We know that this suggestion might sound like an urban myth, but there is nothing subtle about how a tanker truck dispenses fuel into gas station holding tanks. Thousands of gallons of fuel are dumped into a tank rapidly, stirring up sediment, debris, and even water resting at the bottom.

None of that material is suitable for your fuel system, and it’s best to let the sediment settle before filling up at that station.

3. Inspect Or Replace Filters And Strainers

Filters and strainers are the first and last words in protecting your fuel system. Without them, harmful particulates can mix with a sticky fuel remnant known as gasoline varnish, wreaking havoc on the precision components found in the fuel system and engine. Clogged or damaged filters and strainers can lead to performance loss and premature wear on your internal components.

The first line of defense your fuel system has is a fuel pump strainer that prevents sand, dirt, and foreign objects from clogging or damaging parts. Once a strainer has absorbed all the material it can, it will restrict flow, which puts unnecessary strain on the fuel pump.

Fuel filters serve the same purpose as a strainer and are typically further up in the fuel system chain. Filters defend engine components, such as your fuel injectors and sensors, from anything that manages to get past the fuel pump strainer.

A clogged filter is detrimental to proper fuel flow, and foreign objects are equally harmful to the rest of your fuel system, clogging small passages and causing performance loss or outright mechanical problems.

Always remember that street-focused motorcycles, cars, and trucks will have much higher service intervals than anything off-road oriented. The harsher off-road environment can quickly introduce dust, dirt, and debris into the fuel system, making maintenance schedules far more frequent on dirt bikes, ATVs, and UTVs/Side-By-Sides.

If you want to maintain your fuel system, stick to regularly servicing the smaller components that you may forget about when doing routine maintenance.

Be sure to reference your model-specific manual for exact mileage/hour figures. Our complete line of filters and strainers are designed to withstand harsh fuel additives and ethanol-based gasoline, ensuring filtration and performance.

4. Clean Your Injectors

Fuel injectors do precisely that: Inject fuel into the engine throttle body or cylinder, allowing a precise amount of atomized fuel to be delivered for proper combustion. Injectors are electronically controlled valves operated by a solenoid that must open and close with extreme accuracy.

Over time, deposits can restrict their spray pattern, causing symptoms like performance loss, decreased fuel economy, rough idle, and misfires.

Cleaning injectors do not apply to low-mileage/low-hour vehicles unless they’ve sat unused for long periods. Any late model or high-mileage vehicle can benefit from a thorough injector cleaning.

There are plenty of aftermarket tools, solvents, and fuel additives to help clean your injector system. These products remove varnish, build-up, and deposits from small passages, allowing the injector spray pattern to function as intended.

The most effective way to clean any delicate precision component is using ultrasonic cleaning tools. At-home mechanics can purchase specialized tools, but many authorized service shops have the equipment to perform this task.

Ultrasonic cleaning uses high-frequency sound waves transmitted through a liquid to scrub and clean surfaces through a process known as cavitation. These tools are incredibly adept at removing build-up, oils, and other deposits that might obstruct the spray pattern. Ensuring injectors are spraying properly is necessary to maintain your fuel system.

If you find that your injectors are beyond repair, QFS sells direct replacements from reputable brands such as Bosch, Injector Dynamics, RC Engineering, and Siemens Deka. We also stock PnP adapters and wiring harnesses built to fit seamlessly with their respective fuel injector.

5. Maintain Electrical Components

Electrical gremlins are tough, especially when you’re out having fun on your bike, UTV/Side-By-Side, or personal watercraft. Inspecting and double-checking electrical connections is as crucial as changing fluids according to cited service intervals, although many owners don’t make it part of their routine.

Loose or damaged connectors and wiring can lead to problems beyond intermittent issues. These bad connections could lead to a total failure of a fuel pump, pop fuses or relays, and leave you stranded.

During your routine maintenance, make it a habit to inspect all electrical connections, especially those on off-road oriented vehicles that are subject to running in dirty environments and taking lots of abuse.

It’s also advisable to test critical electrical systems with a voltage meter to detect problems before they cause harm. While you’re there, hit the electrical connections with some contact cleaner to clean the conductive surfaces.

Lastly, those doing long-distance rides or drives should always look at the most common fuses and relays in their fuse box and carry a spare.

At the most basic level, ensuring your battery is healthy and fully charged is a good place to start. Depending on your charging system, a weak battery can reduce fuel pressure and create lean conditions.

Always keep batteries maintained with a modern “smart charger” that not only maintains a full charge but reconditions your battery and provides a long service life.
