Fuel Tank Draining





WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.

WARNING: Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.

WARNING: When handling fuel, always observe fuel handling precautions and be prepared in the event of fuel spillage. Spilled fuel may be ignited by hot vehicle components or other ignition sources. Failure to follow these instructions may result in serious personal injury.

WARNING: Always disconnect the battery ground cable at the battery when working on an evaporative emission (EVAP) system or fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.

WARNING: Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.

1. Release the fuel system pressure. For additional information, refer to Fuel System Pressure Release Service and Repair.

2. Disconnect the battery ground cable.

3. Remove the Fuel Pump (FP) module access cover.





4. NOTE: Clean the FP (Fuel Pump) module connections, couplings, flange surfaces and the immediate surrounding area of any dirt or foreign material.

NOTE: Place absorbent toweling in the immediate surrounding area in case of fuel spillage.

Disconnect the fuel tank jumper tube-to-FP (Fuel Pump) module quick connect coupling. For additional information, refer to Quick Connect Coupling .





5. Attach the Fuel Storage Tanker tube to the FP (Fuel Pump) module outlet fitting and remove one-fourth (approximately 5 gallons) of the fuel from a completely full tank, lowering the fuel level below the fuel level sensor mounting flange.





6. Remove the fuel level sensor access cover.





7. NOTE: Clean the fuel level sensor connections, flange surfaces and the immediate surrounding area of any dirt or foreign material.
Disconnect the fuel level sensor electrical connector.






8. Disconnect the 2 fuel vapor tube-to-fuel level sensor quick connect couplings. For additional information, refer to Quick Connect Coupling .





9. NOTICE: Carefully install the Fuel Tank Sender Unit Wrench to avoid damaging the fuel level sensor when removing the lock ring.

NOTE: Place absorbent toweling in the immediate surrounding area in case of fuel spillage.

NOTE: Make sure to install a new fuel level sensor O-ring seal.
Install the Fuel Tank Sender Unit Wrench and remove the fuel level sensor lock ring.






10. Position the fuel level sensor aside, insert the tube from the Fuel Storage Tanker into the fuel level sensor aperture and remove as much of the remaining fuel as possible from the fuel tank.
