The auxiliary fuel pump module assembly contains the following components:

• An internal inlet fuel filter
• A separate fuel pick-up
• A lock-ring to retain pump module to tank
• A soft gasket between tank flange and module
• Auxiliary fuel pump module supply line connection (1)
• A fuel gauge sending unit (fuel level sensor) (2)

If the fuel gauge sending unit or internal inlet fuel filter require service, the auxiliary fuel pump module must be replaced as an assembly.
