Fuel Tank Purging

PROCEDURE:

1. Remove the fuel tank and modular fuel level sending unit assembly from the tank and drain all of the remaining fuel from the tank. See COMPONENT SERVICE AND REPAIR PROCEDURES.
2. Visually inspect the interior of the tank. If any fuel is evident, drain again.
3. Move the tank to a flushing area.
4. Fill the tank completely with hot water for at least five minutes, agitate vigorously and drain.
5. When empty, refill the tank until it is overflowing with water. Completely flush out the remaining water and empty the tank.
- If available, an explosion meter should be used to check for a negative reading.
6. Perform the required service work.
