A burning fuel pump affects the performance of an ATV to a great extent since it maintains the level of fuel pressure and any disturbances lead to expensive repairs.
But fret not! Here we will guide you through all the potential causes of fuel pump burning and provide solutions to these problems.
Your ATV might be burning up fuel pumps due to a faulty fuel pressure regulator, clogged fuel filter, overheating, wear and tear, electrical issues, or contaminated or low-quality fuel.
In this article, we are going to discuss why ATVs are burning up fuel pumps and how to fix the issue.
Reasons Why Atv Is Burning Up The Fuel Pump And How To Fix It
Faulty fuel pressure regulator
The fuel pressure regulator must maintain a steady flow of fuel to the engine. If it doesn’t work properly then it results in inconsistent fuel supply to the engine, overheating, and fuel pump failure. All these faults lead to the burning of fuel pumps.
- First of all, locate the fuel pressure regulator that is located near the fuel rail
- The next thing you need to do is to remove the fuel pump fuse that will depressurize the fuel system
- Once the fuel system is depressurized, open the screws and bolts of the fuel regulator with the help of pliers and a wrench and then remove it.
- Install a new fuel pressure regulator by consulting the company’s manual and following all the steps properly.
- Once you are done with the installation, run the engine of your ATV and check if everything is working well.
Clogged fuel filter
A clogged fuel filter obstructs the flow of fuel to the engine. It makes the fuel pump work harder which leads to its overheating and even failure.
- First of all, remove the fuel filter using a wrench or pliers that is usually located between the carburetor and fuel tank.
- Check carefully if there are any signs of damage then you need to replace it or clean it.
- Using compressed air can blow out all the stuck air and debris from the filter
- Then take a cleaning solution or gasoline and soak the filter element in it.
- Once you are done with cleaning, reconnect it to the fuel line.
- Run the engine to check if everything is working properly.
Overheating damages the fuel pump by electrical components to malfunction, wear, and tear, obstructing the fuel from reaching the engine.
- First of all, check the coolant level if it is low then add more coolant to it.
- Debris obstructs the airflow in the radiator which leads to overheating. Therefore remove all dust from it.
- Start your atv and check the temperature frequently.
Wear and tear
With time inner components of the atv can become worn or corroded which leads to the failure of the fuel pump.
- First, inspect your atv completely to check all signs of damage
- You need to check brakes, tires, filters, bolts, and screws
- If they can be repaired then go for it otherwise install new components
- You can take help from the company’s manual for the process of installation.
Electrical issues cause the fuel pump to overheat and which results in its failure and sometimes it burns out permanently.
- Inspect wiring, fuses, and relays to find out the actual problem
- Use a multimeter to test current, proper voltage, and resistance
- Repair all the damaged parts but if they cannot be repaired then replace them with new parts
Contaminated or low-quality fuel
Blocked dirt and debris in the fuel filter increases the workload which leads to the failure of the fuel pump.
- First of all, drain the whole fuel tank
- They replace the fuel filter to get rid of contaminated materials
- It is better to clean the fuel system with good-quality cleaning solutions to remove all rust and debris
- After cleaning, refill the tank with high-quality fuel to avoid further problems.
In short, an ATV burns up the fuel filter due to a malfunctioning fuel pressure regulator, dirty air filter, contaminated or low-quality fuel, or mechanical or electrical issues.
Here we have discussed all the potential causes along with their solutions.
If the problem persists then take your vehicle to a professional to have it fixed properly.
