Secondary Fuel Pump Module (AWD)
The secondary fuel pump module (AWD) is mounted on the top of the fuel tank and contains the following components:
- Mounting flange
- Fuel pick-up
- Fuel level sending unit
The secondary fuel pump module (AWD) does not pump fuel. It is joined to the primary fuel pump module by an internal nylon fuel transfer line (1) equipped with quick-connect fittings. Fuel is constantly being siphoned from the secondary side of the fuel tank to the primary side of the fuel tank whenever the fuel pump is operating.
The fuel level sending unit (2) on the secondary fuel pump module is not serviceable. If any component of the secondary fuel pump module requires service, the secondary fuel pump module must be replaced as an assembly.
