Caution: In order to reduce the risk of fire and personal injury that may result from a fuel leak, always replace the fuel sender gasket when reinstalling the fuel sender assembly.

1. Relieve the fuel system pressure. Refer to Fuel Pressure Relief .
2. Remove the rear compartment liner. Refer to Rear Compartment Trim Panel Replacement .
3. Remove the fuel sender access hole cover bolts.
4. Remove the fuel sender access hole cover.



5. Disconnect the fuel feed rear pipe quick connect fitting (3) from the module. Refer to Plastic Collar Quick Connect Fitting Service .
6. Disconnect the fuel level sensor wiring harness electrical connectors (1, 2) from the pressure sensor and module.
7. Reposition the fuel feed pipe and harness connectors out of the way.



8. Install the J 45722 to the lock ring.




Notice: Avoid damaging the lock ring. Use only J-45722 to prevent damage to the lock ring.

Notice: Do Not handle the fuel sender assembly by the fuel pipes. The amount of leverage generated by handling the fuel pipes could damage the joints.

Important: 

•	The fuel module assembly may spring up from its position.

•	When removing the fuel module assembly from the fuel tank, be aware that the reservoir bucket is full of fuel. It must be tipped slightly during removal to avoid damage to the float. Discard the fuel module assembly O-ring seal and replace it with a new one.

•	Carefully discard the fuel in the reservoir bucket into an approved container.

Important: Do NOT use impact tools. Significant force will be required to release the lock ring. The use of a hammer and screwdriver is not recommended. Secure the fuel tank in order to prevent fuel tank rotation.

9. Use the J 45722 and a long breaker-bar in order to unlock the fuel module lock ring. Rotate the lock ring in a counterclockwise direction.



10. Remove the J 45722 and the fuel module lock ring.
11. Slowly raise the module until the fuel level sensor float arm is just visible.

Important: When removing the module from the fuel tank, be aware that the module reservoir bucket is full of fuel. The module must be tipped slightly during removal to avoid bending the fuel level sensor float arm.

12. Tilt the module toward the rear of the fuel tank to allow the level sensor float arm to clear the tank opening. Remove the module from the tank.
13. Carefully discard the fuel in the module reservoir bucket into an approved fuel container.

Important: DO NOT reuse the old fuel pump module seal.

14. Remove and discard the fuel pump module O-ring seal.

•	Inspect the lock ring for damage due to improper removal or installation procedures. If damage is found, install a NEW lock ring.

•	Check the lock ring for flatness.

15. Place the lock ring on a flat surface. Measure the clearance between to lock ring and the flat surface using a feeler gage at 7 different points.
16. If the warpage is less than 0.41 mm (0.016 in), the lock ring does not require replacement.
17. If the warpage is greater than 0.41 mm (0.016 in), the lock ring must be replaced.

1. Place a NEW fuel pump module O-ring seal onto the fuel tank.

Important: The bucket must be tipped slightly during installation to avoid bending the fuel level sensor float arm.

2. Tilt the module toward the rear of the fuel tank to allow the fuel level sensor float arm to clear the tank opening. Install the module into the fuel tank.
3. Lower the module assembly into the tank.
4. Install the module lock ring, and move it into position on the top of the module.



5. Install the J 45722 to the lock ring.




Important: Always replace the fuel sender seal when installing the fuel sender assembly. Replace the lock ring if necessary. Do not apply any type of lubrication in the seal groove.

Ensure the lock ring is installed with the correct side facing upward. A correctly installed lock ring will only turn in a clockwise direction.
6. Using the J 45722 and a breaker bar, rotate the fuel pump module lock ring clockwise until the ring is locked into place on the fuel tank.
7. Remove the J 45722 .



8. Position the fuel feed pipe and harness connectors.
9. Connect the fuel level sensor wiring harness electrical connectors (1, 2) to the pressure sensor and module.
