Electronic Returnless Fuel Pump Module (FPM)
The fuel pump (FP) module (Figure 71),(Figure 72) and(Figure 73) 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.
