Fuel Tank Purge Procedure

PROCEDURE:
1. Remove the fuel tank, fuel level sending unit, and the fuel pump assembly from the tank, and drain all of the remaining fuel from the tank. Refer to Powertrain Management/Fuel Delivery and Air Induction/Fuel Tank/Service and Repair.
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 tap water, agitate vigorously and drain.
5. Add a fuel emulsifying agent to the tank, refill with water, agitate the mixture for 10 minutes, and drain the tank completely.
6. When empty, refill the tank until it is overflowing with water. Completely flush out the remaining mixture and empty the tank.
- If available, an explosion meter should be used to check for a negative reading.
7. Perform the required service work.
