Tools Required

J 43827 Fuel Sending Unit Wrench

Caution: Do not allow smoking or the use of open flames in the area where work on the fuel or EVAP system is taking place. Anytime work is being done on the fuel system, disconnect the negative battery cable, except for those tests where battery voltage is required.

1. Remove fuel tank. (Refer to "Fuel Rail Removal" procedure in this section of the service manual.)
2. Remove fuel lines and electrical connector from fuel pump cover.

Notice: To prevent retaining ring damage, do not attempt to remove the retaining ring with a 12 inch or shorter ratchet/breaker bar. Operation should be a smooth one-hand operation while holding onto the lock ring.

3. Use J 43827 and remove fuel pump module retaining ring. A 1/2 in. breaker bar (approximately 18 inches long) will easily loosen and remove the lock ring.



4. Pull up fuel pump module cover and disconnect the sending unit electrical connector on the bottom side of the fuel pump module cover (be sure to release retaining clip).
5. Remove the sender by depressing locking tab and pulling up. The locking tab is square not round.

Important: The fuel pump assembly is only serviced as a module without the sender unit. The inlet filter can be cleaned with mineral spirits; however, it cannot be replaced.

1. Slide new sender unit into place until click is heard. (Pulling up lightly to ensure sender unit is locked into place.)

Important: Verify that float arm on sender unit maintains correct relationship to pump module by standing module on a flat, horizontal surface. The float should lay on the surface.

To verify function and calibration of sending unit, refer to "Fuel Tank Unit Calibration and Electrical Circuit" procedures in this service manual.
2. Connect electrical connector.

Important: The fuel pump module to tank seal must always be replaced whenever module is removed from fuel tank.

3. Install pump module cover and lock ring using a new tank seal.
4. Reconnect fuel lines and electrical connector to fuel pump cover.
5. Install fuel tank. (Refer to "Fuel Tank" installation procedure in this section.)
