Failure Symptoms

Early indicators include intermittent engine hesitation or stumbling, especially under load, and a slight decrease in fuel economy. If left unaddressed, the pump's output will diminish further, leading to persistent power loss and potential stalling. A completely failed fuel pump will prevent the engine from starting altogether.

Installation Tip

Ensure the fuel tank is at least half full to prevent the pump from running dry during initial priming and testing. Do not overtighten the mounting bolts, as this can distort the pump housing and cause leaks.

Service Note

Always replace the fuel filter when replacing the fuel pump to prevent debris from entering the new pump and to ensure optimal fuel system performance.
