Fuel Pump Troubleshooting FAQ

My car won't start. Do I need to replace my fuel pump?
In most cases, a vehicle's failure to start is usually caused by a faulty, battery, alternator, starter, or fuel pump. If the first three of these parts are determined to be working properly, have someone listen for a vibrating sound that the fuel pump should make near your gas tank when your engine is running. In some vehicles you may be able to hear this sound better by turning the ignition key barely enough to start the engine. If there is no fuel pump noise coming from the gas tank or the sound is very week, chances are that it's time to replace your fuel pump.
My car is jerking while accelerating. Do I need a new fuel pump?
If it's not your engine's tuning, jerking is usually the result of a faulty fuel pump. Follow the same procedure above to listen for the fuel pump.

Fuel Pump Product FAQ

What fuel pump flow rate (LPH) and pressure is suitable for my application?
FuelPumps.com only sells fuel pumps which meet or exceed the manufacturer's recommended flow and pressure. Sending a larger flow of fuel throughout your fuel system will never harm your engine and may actually help your vehicle in several ways. Your fuel injectors and fuel pressure regulator will only allow what is needed to travel into your engine's intake manifold, usually sending back approximately 95% of the fuel from your fuel pump, directly back to your fuel tank via the fuel return line. This helps cool down your gas as well as fragile vehicle components as the fuel passes through.

What is a fuel pressure regulator?
A fuel pressure regulator (FPR) controls the amount of fuel that goes into the intake manifold via the vacuum line after it passes through the injectors.

Fuel Pump Installation FAQ

Can I replace my fuel pump myself?
It is highly recommended that you have a professionally licensed mechanic install your fuel pump. If you are on a low budget or a vehicle enthusiast learning to gain knowledge of the fuel system, many applications have their fuel pump accessible from under the trunk's carpet. Detailed instructions and installation guidelines are included with all fuel pump orders. Please note that malfunctions due to improper installation may void the manufacturer's warranty. If your fuel tank must be removed to access the fuel pump, it is extremely important to have it replaced by a licensed mechanic.
