1. Place a NEW fuel pump sender 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 sender toward the rear of the fuel tank to allow the fuel level sensor float arm to clear the tank opening. Install the sender into the fuel tank.
3. Lower the sender assembly into the tank.
4. Install the sender lock ring, and move it into position on the top of the sender.
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 sender lock ring clockwise until the ring is locked into place on the fuel tank.
7. Remove the J 45722.
