FUEL FILTER

This filter may be a lifetime fuel filter located in the fuel pump assembly or an external 3-port inline filter that allows clean fuel to return to the fuel tank.

The fuel system consists of the following components:

- Fuel tank:
- The midship fuel tank is between the frame side rails on the LH side
- The aft-of-axle fuel tank is mounted at the rear of the vehicle between the frame rails

- Fuel tank filler pipe which contains a restrictor plate to permit only unleaded fuel to be pumped into the fuel tank
- Quarter-turn fuel tank filler cap
- Fuel tubes
- Vapor tubes
- Fuel Pump (FP) and sender assembly which provides filtered, pressurized fuel to the engine and a signal to indicate fuel level to the instrument cluster, and contains:
- a serviceable fuel sender.
- an inlet filter.
- a check valve that maintains system pressure after the FP is shut off.
- a lifetime fuel filter.
