Can a fuel pump be too powerful?
Using the wrong fuel pump that delivers excess pressure can cause problems ranging from poor performance and lower gas mileage to flooding and carburetor damage. When the pressure is only a little over the required amount, your vehicle may sputter when you first accelerate from a stopped position.
Will a fuel filter reduce fuel pressure?
A fuel pump draws gasoline from the tank through fuel lines and delivers it to the engine via fuel filter. Any restriction or leakage in the lines can reduce the pressure and may impact the delivery of fuel to the engine.
How do you know if your fuel pump is going out?
