2. Raise the vehicle.
3. Remove the off-road shield, if applicable.



4. Loosen the filler neck hose clamp (2) at the fuel tank (1).
5. Disconnect the filler neck hose (3) from the fuel tank.
6. Support the fuel tank.



7. Remove the fuel tank bolts (4), straps (3) and the insulator strips, if applicable.
8. Lower the fuel tank (2) and the fuel tank shield.
9. Disconnect the fuel feed and the vapor hoses.
10. Disconnect the electrical connections at the fuel sender assembly.



11. Use the J 36608 fuel sender tool in order to remove the fuel sender assembly and the seal ring. Discard the old seal ring.
12. Purge the tank if the tank is being repaired.

1. Install a new seal ring.
2. Use the J 36608 fuel sender tool in order to install the fuel sender assembly .
3. Raise the tank slightly.
4. Reconnect the fuel feed and the vapor hoses.
5. Reconnect the electrical connector to the fuel sender assembly.
6. Raise the fuel tank fully.



7. Reinstall the fuel filler neck (3) to the fuel tank (1).

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

8. Install the clamp (2).

Tighten
Tighten the clamp to 2.5 N·m (25 lb in)




9. Install the fuel tank brackets (3) with the insulator strips in place.

Notice: Tighten the strap fasteners by steps, alternating between the fasteners, until the specified torque is reached. A failure to tighten the strap fasteners as specified will cause the bottom of the tank to flex upward. This will result in the fuel gauge indicating that there is fuel remaining in the tank when the tank is empty.

Tighten
Tighten the fuel tank bolts (4) to 45 N·m (33 lb ft).

10. Install the fuel tank off-road shield, if applicable.
11. Replenish the fuel in the fuel tank (2).
12. Reinstall the fuel tank filler cap.
13. Reconnect the negative battery cable. If a memory retention device was not used, reset (to the extent possible) all of the devices that lost their memory after the battery was disconnected.
14. Check for leaks.
