16. Disconnect the chassis wiring harness electrical connectors (1) from the module and the fuel pressure sensor.




17. Completely lower the fuel tank.
18. With the aid of an assistant, place the fuel tank in a suitable work area.
19. If replacing the fuel tank proceed to the next step, otherwise proceed to step 18 in the installation procedure.




20. Remove the fuel feed line from the retaining feature (2) in the fuel tank.
21. Open the fuel/EVAP line clip (1) and remove the fuel feed line from the clip.
22. Disconnect the fuel feed line quick connect fitting at the fuel tank module.




23. Remove the fuel feed line from the fuel tank.




24. Remove the fuel tank shield retainers (2 and 3) and shields (1 and 4).




25. Remove the EVAP line from the fuel tank clips (2 and 6).
26. Open the fuel tank clips (1, 3, 4, and 5) and remove the EVAP lines from the clips.
27. Disconnect the EVAP line quick connect fittings at the fuel tank module and fuel tank vent valve.




28. Remove the EVAP lines from the fuel tank.




29. Using the J 45722, remove the lock ring.




30. Carefully lift the module from the fuel tank, enough to access the quick connect fittings (1) under the module cover. Disconnect the quick connect fittings.
31. Remove the fuel tank module.
32. Remove and discard the fuel tank module seal.

33. IMPORTANT:
- Some lock rings were manufactured with "DO NOT REUSE" stamped into them. These lock rings may be reused if they are not damaged or warped.
- 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.




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

INSTALLATION PROCEDURE




1. If the fuel tank was replaced perform the following steps, otherwise proceed to step 18.

4. Position the fuel tank module part way into the fuel tank.
5. Connect the quick connect fittings (1) to the module cover.
6. Install the fuel tank module into the fuel tank.
7. Place the lock ring into position.

8. IMPORTANT:
- Always replace the fuel module seal when installing the fuel module. 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.




Rotate the lock ring counterclockwise using the J 45722.
