The main fuel pump module assembly contains the following components:

An internal fuel filter
A separate fuel pick-up, or inlet filter
A fuel pressure regulator
Fuel supply fitting (1)
An electric fuel pump (2)
A lock-ring to retain pump module to tank
A soft gasket between tank flange and module

If the electrical fuel pump, primary inlet fuel filter, internal fuel filter, or fuel pressure regulator require service, the fuel pump module must be replaced as an assembly.
