    CAUTION: Avoid damaging the lock ring. Use only J-45722 to prevent damage to the lock ring.
    CAUTION: 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.
    NOTE: 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.
  5. Use the J 45722  (1) and a long breaker-bar in order to unlock the fuel sender lock ring. Turn the fuel sender lock ring in a counter-clockwise direction.

    NOTE:
    • 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.
  6. 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.
  7. If the warpage is less than 0.41 mm (0.016 in), the lock ring does not require replacement.
  8. If the warpage is greater than 0.41 mm (0.016 in) the lock ring must be replaced.

    NOTE: When removing the fuel pump module from the fuel tank, be aware that the pump module reservoir bowl is full of fuel. The reservoir must be tipped slightly during removal to avoid bending the fuel level sensor float arm.
  9. Slowly lift the fuel pump module (2) up until the fuel level sensor float arm is just visible. Ensure that the fuel level sensor harness connector clears the tank opening.
  10. Tilt the fuel pump module (2) toward the front of the fuel tank to enable the level sensor float arm to clear the tank opening. Remove the pump module (2) from the tank.
  11. Remove the fuel pump module lock ring (1).
  12. Discard the fuel in the pump module reservoir bowl into an approved fuel container.
  13. If only replacing the module, remove the fuel level sensor. Refer to Fuel Level Sensor Replacement .
    14. NOTE: Do NOT reuse the old fuel pump module-to-fuel tank seal.
  14. Remove and discard the fuel pump module seal (3).
