Fuel System Cleaning Procedure

REMOVE:

NOTE: Have a dry chemical (Class B) fire extinguisher near the work area.

- Negative battery cable.
- Engine harness connector on the distributor.
- Fuel from the tank. Refer to FUEL TANK DRAINING
- Fuel tank. Refer to COMPONENT REPLACEMENT AND REPAIR PROCEDURES/FUEL TANK ASSEMBLY.
- Fuel gauge and pump unit.
- In-line fuel filter.

INSPECT:

- In-line fuel filter, for contamination.
- Replace the fuel filter, if it is plugged.

CLEAN:

- Fuel lines, by applying air pressure in the opposite direction of the fuel flow.

INSTALL:

NOTE Care should be taken not to fold over or twist the strainer, when installing the sending unit, as this will restrict fuel flow.

- A new fuel strainer (if necessary) on the fuel sender and pump unit.
- Fuel gauge and pump unit, with a new seal into the fuel tank.
- Fuel tank.

PURGE:

- Disconnect the fuel feed line at the front of the vehicle.
- Install a hose to the fuel feed line at the front of the vehicle and insert the other end of the hose into a 3.8L (One gallon) fuel can.
- Reconnect the negative battery cable.
- Fill tank with twenty-three liters (six gallons) of clean fuel into the tank.
- Energize the fuel pump relay, to operate the fuel pump, until two liters (one half gallons) of fuel flows into the fuel can. This will purge the fuel pump.

CONNECT:

- Engine harness connector to the distributor.

CHECK:

- Check all connections, for leaks, and tighten all hose clamps.
