FUEL SENDER ASSEMBLY REPLACEMENT (SHORT WHEEL BASE)

TOOLS REQUIRED
J 45722 Fuel Sender Lock Nut Wrench

REMOVAL PROCEDURE




1. Remove the fuel tank.

NOTE: 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.

2. Disconnect the fuel sender electrical connections (4)
3. Clean all of the fuel pipe connections, all of the hose connections, and all of the areas surrounding the connections before disconnecting the connections in order to avoid possible contamination of the fuel system.
4. Disconnect the fuel supply pipe quick-connect fitting (3) at the fuel sender assembly.
5. Disconnect the evaporative emission (EVAP) pipe quick-connect fittings (5, 6) at the fuel sender assembly.




6. Use the J 45722 and a long breaker-bar in order to unlock the fuel sender lock ring. Turn the fuel sender lock ring in a counterclockwise direction.

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

7. Remove the fuel sender assembly (7) and the seal (2) from the fuel tank.

CAUTION: Drain the fuel from the fuel sender assembly into an approved container in order to reduce the risk of fire and personal injury. Never store the fuel in an open container.

8. Discard the fuel sender assembly seal.
9. Clean the fuel sender assembly sealing surfaces.




10. 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 points.

IMPORTANT:
- Some lock ring 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.

11. If the warpage is less than 0.41 mm (0.016 in), the lock ring does not require replacement.
12. If the warpage is greater than 0.41 mm (0.016 in), the lock ring must be replaced.

INSTALLATION PROCEDURE




1. Position the new fuel sender assembly seal (2) on the fuel tank.

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.

2. Install the fuel sender assembly (7) into the fuel tank.

IMPORTANT: Care should be taken not to fold over or twist the fuel pump strainer when installing the fuel sender assembly, as this will restrict fuel flow. Also, ensure that the fuel pump strainer does not block full travel of float arm.




3. Use the J 45722 in order to install the fuel sender lock ring. Turn the fuel sender lock ring in a clockwise direction.

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.

4. Connect the fuel supply pipe quick-connect fitting (3) at the fuel sender assembly.
5. Connect the EVAP quick-connect fittings (5, 6) at the fuel sender assembly.
6. Connect the fuel sender electrical connections (4)
