Fuel Pump Module: Description

The fuel pump module assembly is located in the fuel tank. See Figure. The assembly is divided into 2-sections, upper and lower. The lower section is locked to the bottom of the fuel tank. The complete assembly contains the following components:

• A fuel pressure regulator
• A separate fuel pick-up, or inlet filter
• An electric fuel pump
• A lockring to retain upper section of pump module to tank
• A rollover valve
• A vent fitting for ORVR system
• A soft gasket between tank flange and module
• A fuel gauge sending unit (fuel level sensor)
• Two fuel line connections (supply and return)

  The fuel gauge sending unit may be serviced separately. If the electrical fuel pump, primary inlet filter or fuel pressure regulator require service, the lower section of the fuel pump module must be replaced.
