The fuel pump module assembly (2) is located on top of the fuel tank. The complete assembly contains the following components:

1. A fuel pressure regulator
2. A built-in primary fuel filter
3. A separate fuel pick-up, or inlet filter
4. An electric fuel pump
5. A lockring (3) to retain pump module to tank
6. A soft gasket between tank flange and module
7. A fuel gauge sending unit (fuel level sensor)
8. A fuel line connection

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