How to Diagnose a Bad ATV, Motorcycle, UTV/Side-by-Side Fuel Pump
Understanding the symptoms and how to diagnose a bad fuel pump on an ATV, motorcycle, or UTV/SxS is handy knowledge for any enthusiast and precisely what we’ll be discussing below. When a fuel pump fails to operate within its designed specifications, your EFI-powered vehicle can suffer in a few ways. Expect lowered performance, causing it to run poorly, or failing to start at all.
A properly functioning fuel pump is one of the many crucial components in your ATV, motorcycle, or UTV/Side-by-Side (SxS).
Quantum Fuel Systems specializes in high-quality direct OEM replacement fuel system and engine management components. All QFS products are backed by an industry-leading lifetime warranty. Every product in our extensive Powersports product line is designed to match the technical specifications of your vehicle.
We know how important it is for our customers to get back on the road or trail. Your orders are processed the same business day, and we offer free 2-day shipping in the United States with any purchase above $60. QFS has you covered with complete replacement kits, individual parts, specialty tools, and more.
Whether we’re talking about two or four-wheeled vehicles, testing a bad fuel pump, or issues related to your fuel system are similar. It doesn’t matter if you drive an Arctic Cat, Can-Am, or Polaris, ride a Harley-Davidson, Honda, or Husqvarna. Fuel pumps can fail anytime, anywhere.
What does matter is that you’re referencing your vehicle-specific service manual to confirm any necessary technical specifications, as those figures can change depending on the vehicle year, make, and model.
Luckily, troubleshooting a bad fuel pump follows the same general principles, and we’ll be covering a few basic and advanced methods.
QFS does not intend this article to be a strict guide. As always, we recommend that only those confident in their mechanical abilities perform maintenance, repairs, and diagnosis on their vehicles.
If you do not feel comfortable performing this work, please consult an authorized and licensed service technician.
Let’s dive into it with how to diagnose a bad fuel pump and review some tell-tale symptoms of an underperforming or failed fuel pump.
Not Starting/Won’t Idle
Not starting when all systems appeared to be in regular working order is a good indicator that fuel is not making it through the fuel system. If the engine does start but fails to maintain idle, that is another sign that the pump is on its way out.
All fuel pumps produce a low audible hum when operating. When they reach the end of their lifespan, you may notice a loud whining sound, pointing to a fuel pump motor stressing itself to function.
In-Tank Fuel Pump Assembly for 2016-2023 Polaris RZR Turbo
Surging occurs when traveling at a constant speed and feels as if your ATV, motorcycle or UTV briefly accelerates with no input from the user. Typically, excessive pressure buildup can momentarily deliver excess fuel. In this case, we strongly recommend replacing the pump and filters immediately.
Power Loss Under Load/Cut outs
Does your bike, quad, or SxS accelerate normally only to begin losing power as the rpm climb or at higher rpm? That is often a signal of a fuel pump that cannot deliver the correct amount of fuel pressure to meet performance demands. Alternatively, you may experience power cut-outs at random, demonstrating a fuel pump operating sporadically.
Diagnosing a Failing Fuel Pump
Pinning-down fuel issues can be complex, as fuel systems and electrical systems are interdependent. Problems with one system can cause the other to malfunction. Our goal here is to isolate variables and help you determine the root cause of your issues.
Before you turn a single wrench, start with the basics and confirm a few things:
Is there fuel in the tank, and does your fuel gauge (if applicable) register accurately?
Is your battery adequately charged, and does your electrical system appear to be fully operational?
Is the kill switch in the “run” position?
Is your bike, SxS, or quad in neutral?
If you’ve answered yes to all those questions and you’re still experiencing issues, then it’s time to start investigating.
Fuel Pump Won’t Prime
Fuel pumps can fail with or without warning. We go to fire up our ATV, motorcycle, or UTV; the engine cranks, and it simply won’t start. Our first step is to observe if the fuel pump is operational and “priming.”
Priming means that the fuel pump engages for a short time, pressurizing the fuel lines and providing adequate fuel flow for the injectors.
To test this, cycle your key to the “on” position and listen intently for an audible hum coming from the fuel tank. The hum should only last a few seconds.
If you’ve repeated this multiple times and don’t hear a mechanical whirring, chances are the fuel pump has failed or is not being supplied electricity.
If you are performing this test on a dirt bike (Motocross or Enduro) that doesn’t have a keyed ignition, press the starter button and quickly release, which will trigger the fuel pump and allow you to determine if the fuel pump is operational.
Check the Fuel System Fuses & Relays
Fuses and relays act as bridges for electrical current. If they fail, the current can’t reach its proper destination and provide power. Consult your service manual to access your fuse box and relays, and then remove them to inspect them for any damage visually.
A healthy fuse will have its metal “bridge” connected, and a functional relay will “click” when power is delivered. You can also use a multimeter to check the resistance of a relay or fuse, which is more accurate.
Confirming Your Fuel Pump Has Power
If your fuel pump is not priming, you must determine if this is an electrical problem or a fuel pump failure. To do that, you will need to gain access to your vehicle’s fuel pump assembly. Consult your model-specific service manual for instructions to perform this safely.
Once you have clear access to the fuel pump assembly, you will want to test if power is coming down to the fuel pump itself with a multimeter or voltage meter.
Disconnect the wiring from the fuel pump assembly. Again, you will need to consult your service manual and wiring diagram to determine which terminal connections to measure.
Once you’ve done that, confirm that adequate power is available by cycling the key to the “on” position and measuring the voltage — it should rise to the cited technical specification in your service manual, then fall to zero after a few seconds. If you don’t have power or insufficient voltage, you know that the issue is not related to your fuel system.
If all is in order with the wiring harness, perform a continuity test with your multimeter on the fuel pump itself. Locate the positive and negative leads going to the fuel pump and check if an electrical connection is capable.
If it isn’t, rest assured that the fuel pump motor is dead.
Pressure Testing a Fuel Pump
Pressure testing is crucial when faced with lean and rich conditions, power loss, or surging, as irregular pressure in your fuel system can cause these issues. This test requires one of the few specialized tools mentioned here since it will need a gauge with model-specific connections to be installed between the vehicle’s fuel pump and fuel lines.
Once you’ve determined your vehicle’s fuel pressure specifications and installed the pressure tester, cycle the key to the “on” position. Pressure must raise and hold at the required specification.
If that checks out, start the engine and increase the rpm gradually. Once again, pressure should not deviate outside the recommended range.
If pressure is excessively high, your pressure regulator has failed, and we offer replacement options. Conversely, clogged fuel filters can lower fuel pressure and create flow issues.
Inspect all relevant filters thoroughly, although we recommend replacing them during this type of service. To accurately diagnose a bad fuel pump, all other fuel system components must be thoroughly checked.

Fuel hoses, often inconspicuous under the hood of our vehicles, are vital components responsible for delivering fuel from the tank to the engine. Ensuring that the fuel system functions properly is crucial for a vehicle’s performance and safety. Unfortunately, fuel hoses are not immune to wear and tear, and when they fail, it can lead to a host of problems, from reduced performance to potential safety hazards and expensive repairs. In this blog, we’ll explore the causes of fuel hose failure, how to recognize the signs of trouble, and, most importantly, how to prevent these issues from affecting your automotive experience.
Understanding the Causes of Fuel Hose Failure
The primary causes of fuel hose failure are numerous, and they include:
Misapplication: Using the wrong type of hose for a particular fuel or application.
Kinking near fittings: Excessive bending and crimping near hose fittings can lead to restricted fuel flow and structural damage.
Temperature Extremes: Exposure to high heat or freezing cold can weaken hose materials.
Surging Pressure: Rapid pressure changes can cause hoses to weaken and rupture.
External Damage: Physical impacts, abrasive surfaces, or chemical exposure can lead to hose damage.
Inadequate Bend Radius: Hose bending beyond its recommended radius can cause kinking and structural stress.
Defective Hoses or Improperly Selected Clamps: Using low-quality hoses or mismatched clamps can lead to premature failure.
Incompatible Materials: Fuel hoses must be compatible with the type of fuel they carry to prevent degradation.
Incorrect Hose Length: Incorrectly sized hoses may twist, kink, or strain, leading to damage.
Twisting During Installation: Improper hose installation, such as twisting during fitting, can create weak points.
Transfer of Contaminated Media: Contaminants in the fuel can accelerate hose deterioration.
Age, improper installation, and lack of maintenance can also contribute to hose deterioration. Contaminants in the fuel can exacerbate hose degradation.
Recognizing Signs of Fuel Hose Failure
Fuel hose failure is often indicated by:
Fuel Odors: A strong gasoline odor clearly indicates a fuel leak and a significant safety concern.
Visible Cracks or Leaks: Inspecting hoses for visible cracks, bulges, or signs of leakage is crucial.
Preventing fuel hose failure requires a proactive approach:
Regular Inspection: Regularly inspect your vehicle’s fuel hoses during maintenance to identify early signs of wear or damage.
Use Quality Hoses: Invest in high-quality hoses designed for fuel applications.
Proper Installation: Follow manufacturer guidelines for hose installation to prevent excessive bending, twisting, or tension.
Protective Shields and Covers: Consider protective shields and abrasion-resistant covers for hoses exposed to potential damage.
What Type of Fuel Lines Should You Use?
Fuel lines can be crafted from a variety of materials, including Metal, Rubber, Braided, or PTFE Lined options. When considering the right choice, especially for racing purposes, it’s essential to consult the rule book for your track or sanctioning body. Selecting the appropriate material from the outset can help you save time, and money, and prevent future headaches.
Most factory-fitted fuel lines are constructed from Metal, known for its superior durability compared to softer materials. These Metal Lines are typically made from stainless steel, aluminum, or coated steel tubing. Metal is considered the optimal material for fuel lines, although it can be challenging to work with due to its rigidity.
Rubber fuel hoses are renowned for their ease of installation, typically connected using standard barbed fittings and Fuel Line Hose Clamps. It’s crucial to ensure that the rubber hose is rated for fuel and complies with specific SAE grades:
SAE J30R7 is suitable for carburetor-rated fuel hoses, suitable for limited runs up to 50 psi.
SAE J30R9 is designed for fuel injection and can withstand up to 100 PSI pressures.
Braided Rubber Hose:
A braided Hose is essentially a rubber hose with an exterior layer of braided stainless steel or braided nylon. It utilizes a hose Ends for connecting with the rest of the fuel system. While it offers greater durability compared to plain rubber hoses, it shares some of the longevity and fuel vapor issues associated with rubber hoses. Check out our Rubber hoses here…
PTFE Lined Hose:
PTFE Lined Hose is the preferred choice for flexible hose applications and typically features a braided stainless steel or braided nylon exterior. The PTFE liner effectively prevents fuel vapors and retards the degradation process. It’s important to note that PTFE Braided Hoses necessitate the use of special fittings and cannot be paired with standard AN fittings. Additionally, they are less flexible than conventional braided or rubber hoses.
Corrugated Flexible Hose:
Plastic corrugated fuel hose lines offer advantages such as lightweight construction, corrosion resistance, flexibility, and cost-effectiveness. Their durability and resistance to environmental factors make them a practical choice for various applications. Additionally, their smooth interior minimizes condensation and eases maintenance. However, the suitability of plastic corrugated hoses depends on the specific requirements of the application, including the type of fuel and operating conditions.

Balancing Fuel System Upgrades for Maximum Performance
– We answer many questions about upgrading fuel pumps for more performance. One common mistake that is made over and over is not balancing the fuel system for maximum performance and reliability. The fuel pump is just the beginning, and to get the most from your fuel system it should incorporate matching components to the upgraded fuel pump. If you’re shopping for a new fuel pump, be sure to grab the extra matching components too.
What Components Are in the Fuel System?
The fuel system in your car is made up of several components, each of which must function properly to enable proper fuel flow from start to finish.
These are the main fuel system components in your system:
·Fuel pump with pre-screen strainer/filter
·Fuel filter (typically in line with the pressure fuel line)
·Fuel pressure regulator
·Fuel lines (can be both pressure and return lines)
·Fuel injectors + fuel rails
·Replacement / complimentary parts
·The fuel itself (gasoline, diesel, or other)
Fuel Pump – The fuel pump is the beating heart of the fuel system. Where the fuel enters the pump body, most high-pressure fuel pumps contain a pre-screen filter (also known as a sock or strainer). Most new gasoline pumps have a new pre-screen strainer, but if you intend to reuse your present strainer, it must be clean before being reinstalled in the fuel tank. The strainer might become clogged with time, causing hesitation and fuel starvation later on.
Fuel Filter – The fuel filter removes particles such as dust and dirt from the fuel before it reaches the engine and fuel injectors. If your system lacks a primary pressure regulator, the filter may also serve as a pressure regulator for the fuel system. Most automakers have a recommended replacement frequency for preventative maintenance, but if you’re updating the gasoline pump, it’s a good time to replace the fuel filter as well. Install a filter that can handle the increased fuel volume required by the improved system.
Fuel Pressure Regulator – A pressure regulator in fuel injection systems maintains a steady pressure within the system. Some OEMs integrate the fuel filter and pressure regulator into one unit, but if you want to improve your system for additional fuel flow and horsepower, a separate stand-alone adjustable regulator may be a better alternative. It will enable you to balance the pressure in order to satisfy the demands of the fuel pump, injectors, and fuel lines.
Pressure and Return Fuel Lines – Fuel lines play a vital role in transporting fuel from the tank to the fuel filter, regulator (if separate), injectors, and engine. Manufacturers typically design them to handle the recommended fuel type, such as gasoline or diesel, and with proper maintenance, they can last the lifetime of the vehicle. It’s important to ensure that the fuel lines are the appropriate size to accommodate the engine’s fuel volume requirements. While original equipment manufacturer (OEM) fuel lines usually have sufficient flow capacity for the fuel pump, if you significantly increase the fuel pump size for more power, you need to verify that the lines can still handle the fuel pump’s output. Additionally, using a different fuel type than specified by the manufacturer may cause damage and degradation to standard fuel lines, potentially resulting in leaks. If you plan to switch to a different fuel type, it is advisable to replace the fuel lines with new materials specifically rated for the intended fuel. This ensures proper functionality and prevents any potential issues.
Fuel Injectors + Fuel Rails – The injectors and fuel railsactively spray fuel into the intake manifold, cylinder heads, or directly into the engine cylinders. It is crucial to match the fuel pump’s output volume with the injectors and fuel rails to avoid becoming a restriction in the system. Changing to fuels like E85, methanol, or those with higher ethanol or alcohol content can degrade the injector seals, potentially leading to leaks. Upgrading the injectors with seals designed for the specific fuel type may be necessary, along with potential requirements for adapter harnesses or connectors to facilitate the switch. If you require assistance in calculating the correct injector size or determining the appropriate type for your application, feel free to contact us Monday through Friday, 8:00 AM to 5:00 PM Pacific time, at 1-818-574-FUEL (3835), or email us at firstname.lastname@example.org.
Replacement Parts – Don’t forget that there are other parts in the system that may need attention or replacement due to changing fuel type or degradation from old age. Replacing thefuel tank seal or fuel tank gasket is a great option if you plan to remove and upgrade your current fuel pump. Quantum fuel tank seals are made exclusively from Viton® which are impervious to ethanol and other chemicals that degrade conventional rubber over time. Replacing the tank seal, or gasket during fuel pump installation ensures fuel system longevity and lengthens the lifespan of the fuel pump.
All of the mentioned fuel system components can be replaced and upgraded individually, but the key is to ensure that everything stays balanced for fuel flow and fuel type. Adding a larger fuel pump will only be a benefit if the other components are rated for a comparable flow amount. If you are switching from one type of fuel (such asE10 gasoline to E85 gasoline), always verify that your components are rated for the new fuel type and any change in flow amount. If you need to replace any fuel components, you can order a better designed replacement pump, complete assembly, or just the missing pieces you need for an upgrade from Quantum Fuel Systems, Monday through Friday, 8:00 a.m. to 5:00 p.m. PT, or browse our extensive catalog.

Common Fuel System Issues with Performance Vehicles
Performance is feeling the thrill of speed and acceleration, but without a fuel delivery system that can meet your expectations, the ride may fall a little flat. Many different problems can manifest themselves to diminish performance of your vehicle’s fuel system. From the fuel pump, the lines, and through the fuel injectors, each component can create fuel system issues and hinder the response of your performance vehicle.
Common Symptoms of Fuel System Issues
There are a few key indicators that your fuel system is having some kind of issue. While most can seem similar, they can show themselves in many ways.
These are the more common symptoms you’ll identify:
· A hesitation or stalling engine response
· A No Start or hard starting condition
· Varying performance, throttle response / acceleration at differing speeds
· An engine misfire or sputtering condition (could also be surging)
· Losing power and response when under a load
· Decreasing gas mileage from one tank of fuel to the next
Any of these symptoms can be an indicator that your performance vehicle’s fuel system has an issue. The next thing to do after you detect a problem is to find out what component is the culprit.
What Fuel System Components Can Have Problems?
Your performance vehicle’s fuel system has a handful of components. Each must perform correctly to ensure proper fuel flow from beginning to end.
These are the main fuel system components in your system:
· Fuel pump with pre-screen sock / filter
· Fuel filter (typically in-line with the pressure fuel line)
· Fuel lines (can be both pressure and return lines)
· Fuel injectors + fuel rails
· The fuel itself (gasoline, diesel, or other)
The fuel pump is the heart of the fuel system. Most high-pressure fuel pumps have a pre-screen filter (also commonly called a sock) attached where the fuel enters the pump body. This can become dirty over time, and cause some of the hesitation and fuel starvation issues.
The pump itself has a handful of failure modes that can lead to performance issues. How well they work can be a tell-tale sign that they are having an issue. You may hear the pump have a loud electrical clicking sound or excessive whining when it begins to fail.
If it struggles to build sufficient pressure at start-up, the vehicle may have trouble starting or is harder to start than it has been in the past. Any failing fuel pump can also trigger misfires, sputtering, or cause a losing power condition under a load. You won’t have the necessary fuel to maintain performance, and that is going to cause the system performance to suffer.
The fuel filter removes particulates from the fuel before it travels to the engine and fuel injectors. The filter may also act as a pressure regulator for the fuel system. Your performance vehicle may start to decrease power or throttle response under load. This indicates the filter is nearly full of contaminants and can’t flow enough fuel to the engine.
Most auto manufacturers have a replacement frequency defined for preventative maintenance. However, if find that your vehicle has lost performance it may be time to replace the fuel filter. Most are located under the vehicle in-line with the fuel lines near the fuel tank and just require basic hand tools to replace.
Pressure and Return Fuel Lines
Your fuel lines move the fuel from the fuel tank, to the fuel filter, and then on to the fuel injectors and engine. Most are rated for the type of fuel specified for use (such as gasoline or diesel), and they will typically last the lifetime of the vehicle with proper maintenance.
The main issue with fuel lines is clogging because of debris. If the vehicle is used regularly, you shouldn’t expect that debris will buildup in the lines. The biggest opportunity for buildup is a performance vehicle that sits for extended periods of time without proper maintenance or preparation.
A secondary issue with fuel lines is using a different type of fuel than specified by the manufacturer. Fuels such as E85 or methanol can degrade and damage standard fuel lines, which can cause leaks. If you plan to use a different fuel type than the approved type of the manufacturer, you may want to replace the lines with new material rated for the new fuel type.
Fuel Injectors + Fuel Rails
The injectors and fuel rails spray the fuel into the intake manifold, cylinder heads, or directly in the engine cylinders. They are susceptible to clogging and damage as the other mentioned components are, and they are also rated for a specific fuel type.
As mentioned with the fuel lines, changing to E85, methanol, or another fuel with a higher ethanol or alcohol content can degrade the seals on the injectors and cause a leak. A damaged injector can cause a hesitation with the engine response and performance and can negatively affect your vehicle’s gas mileage.
In many cases the injectors can be kept clean with a fuel treatment solution added to the fuel at the time of a fill up. If the injector is degraded or damaged beyond repair, it will need to be replaced.
The Fuel You Use
If your performance vehicle suddenly has an issue, it may not be the result of a defective or degraded component in the system. It may be the fault of the fuel itself. Gasoline and diesel does have a time period where it keeps stays fresh, but over time it will degrade without preparation for storage.
If you recently filled your fuel tank and suddenly have a performance problem, the fuel may be the wrong type (adding diesel instead of gasoline) or the fuel could be degraded sufficiently to cause a performance problem. If you need to replace the fuel, it may require pumping the fuel tank dry or removing it completely.
You may also need to replace other components like the fuel filter to ensure all of the incorrect fuel has been removed from the system.
Keeping your fuel system in excellent shape is easy with proper maintenance. It can be as simple as adding a fuel system cleaner and treatment every few tanks of fuel. You may also want to avoid driving or storing your vehicle with a low amount of fuel in the tank.
The fuel adds lubrication and cooling to the pump to prevent degradation and overheating.

Replacing a fuel pump can be daunting for any first-timer. It’s tough to know what tools you’ll need or the exact steps, as they differ depending on the vehicle you’re working on. Luckily, there are a lot of commonalities when it comes to replacing fuel pumps, whether you’re talking about a car, truck, motorcycle, snowmobile, boat, or Side-by-Side/UTV.
If you’re nervous about diving into your fuel system for the first time, you’ve come to the right place! We’ll be going through some helpful tips, tricks, and guidelines that will get you prepared to perform a fuel pump replacement in your vehicle.
Your OEM fuel pump will fail and need to be updated with a reliable Quantum Fuel Systems fuel pump. QFS is a fuel system industry leader specializing in direct OEM replacement components for virtually every vehicle on the road, trail, or water today — all backed by a lifetime warranty.
Direct OEM replacement means you’ll never have to worry about our proven products not fitting your application. We painstakingly design our products to be installed as trouble-free as possible.
If you’ve followed our guide on how to diagnose a bad fuel pump and want to take the plunge, then let’s get into what you’ll need, what you’ll need to know, and what you can expect before you start diving into a fuel pump replacement.
Getting these jobs done is approachable, but difficulty levels vary considerably. This article aims to help you determine if you can do it yourself or want to call in the help of an authorized professional, and it shouldn’t be used as a strict guide —there are simply too many vehicle variations to cover. We always recommend that owners have a model-specific service manual to precisely assist them with the process.
Identify and Diagnose
Before you press the checkout button on a shiny new QFS fuel pump replacement kit for your car, truck, boat, motorcycle, ATV, or UTV, you’ll want to ensure it’s the right call.
Be sure to reference the steps in our article, “How to Diagnose a Bad ATV, Motorcycle, UTV/Side-by-Side Fuel Pump,” which has a wealth of information to get you pointed in the right direction. Don’t worry; if you’re working on anything in the automotive world, all the advice there still applies.
There are several symptoms of a bad fuel pump, but these are the most common:
Hard starting (struggling to start)
Failing to idle
While those symptoms can indicate deeper mechanical issues, these symptoms or a combination can often indicate fuel system issues.
Then there’s diagnosis. You’ll want to confirm if the fuel pump is priming, check all fuses and relays, and confirm the pump is getting power and creating enough pressure. If it fails any of those tests, it’s time to break out the tools.
Tools of the Trade
In most cases, you won’t need anything more than a basic set of hand tools to get the job done. But there are plenty of other considerations as well. Since we’ll be dealing with highly flammable fuel and potentially harmful vapors, we’ll want to ensure that we have proper safety equipment and work in a well-ventilated space.
Here’s a short list of the tools you’ll need to have on hand:
Fuel-safe storage container
A complete set of hand tools (metric for foreign vehicles; standard for domestic)
Pex clamp tool
Rags/absorbent for spilled fuel (clay-type cat litter, baking soda, or commercial absorbent)
Floor jack w/ fuel tank-sized block of wood
Siphon or pump to transfer fuel
Weigh Your Options: Do It Yourself or Contact The Pros
Paying a certified mechanic can be incredibly costly between parts and labor. Meanwhile, performing the job yourself in the comfort of your garage will save quite a bit of your hard-earned cash. The question here is: Should you?
There are some considerations. This type of work means you’ll be handling and exposed to flammable fuel, which poses risks. For example, you may need to drain the fuel tank if the entire fuel tank must be dropped from a car, truck, or van or physically removed from a motorcycle/ATV. These types of situations can be labor intensive.
You can probably figure this out if you successfully change a flat tire. Any enterprising at-home mechanic can complete these tasks within an afternoon. QFS fuel pumps are designed to work seamlessly with your specific make and model. But, if you feel your time is more valuable spent elsewhere, having an authorized and licensed mechanic perform the service isn’t a bad route.
Replacing a Fuel Pump
Getting Prepped To Replace Your Fuel Pump
Those feeling confident about working on their rides should understand the level of work they’re committing to on their day off. Of course, a factory service manual will clearly outline every step necessary to upgrade the fuel pump. However, we’ll hit the highlights to paint a clearer picture.
When performing any major service work, always disconnect the negative battery terminal to disable the electrical system to prevent any damage to electrical components and avoid fire hazards.
In addition, you’ll want to secure your vehicle safely. Use jack stands, wheel chocks, motorcycle stands, etc., to ensure your vehicle does not move unexpectedly.
Access The Fuel Pump
Most modern cars, trucks, motorcycles, snowmobiles, and Side-by-Sides/UTVs use “in-tank” fuel pumps inside the fuel tank. This location helps keep the fuel pump cool while submerged in liquid fuel and prolongs its lifespan but makes it difficult to access. Some automobiles and Side-by-Sides/UTVs have a fuel tank access under the seat, making servicing far easier.
Many cars and trucks require that the fuel tanks be unbolted from the undercarriage, which will require the assistance of a floor jack, especially if the fuel tank has fuel in it.
To do that successfully, you’ll want to disconnect the filler neck from the fuel tank and relieve any pressure from the high pressure on the exterior — refer to your model-specific service manual for those steps. Using the floor jack with a block of wood can assist in lowering the fuel tank. Disconnect all electrical connectors, vent hoses, and high-pressure fuel lines if you can access the fuel pump assembly.
Lower The Fuel Tank
Depending on your application, you may need to lower the tank slightly before performing that step.
Nearly all motorcycles, snowmobiles, and quads will need the fuel tank removed to access the fuel pump — that means bodywork surrounding the area will most likely need to be removed. It’s also easiest to manage with the tank drained of all fuel. All the same steps apply here: Disconnect electrical connectors, vent hoses, and fuel lines from the fuel pump assembly.
With the tank lowered or removed, you’ll have clear access to the retaining ring, which secures the fuel pump assembly to your tank. Be sure to clean the ring’s surrounding area so debris or contaminants are not introduced to the tank. Also, inspect the interior of the fuel tank for rust or any other pollutants and remove any settled debris.
Remove The Fuel Pump Assembly
At that point, the entire fuel pump assembly is removed, and the pump is replaced with a high-quality QFS unit. It’s wise to test your new QFS fuel pump with a 12V battery to confirm its operation before replacing your old unit. In addition, all O-rings need to be lubricated with petroleum grease before coupling pressure lines together. Triple-check that all hose clamps (if applicable) are tightened, as minor pressure leaks can cause the fuel pump motor to overwork and lead to premature failure.
QFS fuel pump replacement kits have everything you need to get the job done. Our catalog also offers durable O-rings, gaskets, high-pressure tubing, and all other fuel-system-related required components during this process.
Once the fuel pump assembly is thoroughly inspected and upgraded with QFS components, slide it back into place and always use a new fuel-tank gasket. These gaskets are for one-time use only.
Relocate the fuel tank into position, reconnect all electrical connections, high-pressure lines, and vent hoses, then cycle the ignition several times to pressurize the fuel system.
After completing those steps, you can reconnect your vehicle’s battery and cycle the ignition on/off several times to prime the fuel pump. If the fuel pump is priming and you can hear an audible whirring noise, you can finally start the engine. Once the engine is running, thoroughly inspect for fuel leaks from all fuel lines or gaskets.
While performing this kind of work on your vehicle will differ, these are the significant steps all in-tank fuel pump replacements take. As always, have your vehicle’s service manual handy to reference detailed microfiches. A trained QFS staff will assist you with any technical questions.

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:
265LPH E85 IN-TANK EFI FUEL PUMP
340LPH E85/FLEX IN-TANK EFI FUEL PUMP
Universal, can be doubled for 900+ hp
340LPH E85 INTANK FUEL PUMP
340LPH E85/FLEX IN-TANK EFI FUEL PUMP
340LPH E85 INTANK FUEL PUMP
450LPH E85/FLEX IN-TANK EFI FUEL PUMP
380LPH INLINE EXTERNAL E85 FUEL PUMP
Universal, external mounting
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.
