Fuel pump module

DESCRIPTION

The fuel pump module is installed in the top of the fuel tank (Fig. 1) or (Fig. 2). The fuel pump module contains the following components:

•  A combination fuel filter/fuel pressure regulator
•  A separate fuel pick-up filter (strainer)
•  An electric fuel pump
•  A threaded locknut to retain module to tank
•  A gasket between tank flange and module
•  Fuel gauge sending unit (fuel level sensor)
•  Fuel supply tube (line) connection

The fuel gauge sending unit, pick-up filter and fuel filter/fuel pressure regulator may be serviced separately.

If the electrical fuel pump requires service, the entire fuel pump module must be replaced.
