Fuel Pump Module

FUEL PUMP MODULE


Fuel Pump Module (For Returnable Fuel Systems):






Mechanical Returnless Fuel Pump Module (FPM):






Electronic Returnless Fuel Pump Module (FPM):






The fuel pump (FP) module is a device that contains the fuel pump and sender assembly. The fuel pump is located inside the FP module reservoir and supplies fuel through the FP module manifold to the engine and FP module jet pump. The jet pump continuously refills the reservoir with fuel, and a check valve located in the manifold outlet maintains system pressure when the fuel pump is not energized. A flapper valve located in the bottom of the reservoir allows fuel to enter the reservoir and prime the fuel pump during the initial fill.
