Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable.
2. Relieve fuel system pressure, refer to Fuel Pressure Relief Procedure .
3. Drain fuel tank, refer to Fuel Tank Draining Procedure .

•	Remove the fuel tank, refer to Fuel Tank Replacement (Passenger/Cargo Van)

•	Refer to Fuel Tank Replacement (Commercial/RV Cutaway Van)

4. Remove the fuel sender assembly, refer to Fuel Sender Assembly Replacement .

•	Whenever the fuel tank is cleaned, the fuel pump strainer must be inspected. If the strainer is contaminated, replace the strainer.

•	Inspect the fuel pump inlet for dirt and debris. If found, replace the sender assembly. Refer to Fuel Sender Assembly Replacement .

5. Flush the fuel tank with hot water.

5. Connect the negative battery cable.
6. Install 23 liters (6 gallons) of clean fuel into the fuel tank.
7. Using the scan tool, energize the fuel pump until 2 liters (1/2 gallons) of fuel flows into the fuel can. This will purge the fuel pump.
8. Install the fuel line at the front of the vehicle.
9. Check all the connections, for leaks.
