Removal Procedure
1. Remove the fuel tank.
Notice: Avoid damaging the lock ring. Use only J-45722 to prevent damage to the lock ring.
Notice: 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.
2. 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.
3. Remove the fuel sender assembly (2) and the seal (3). Discard the seal.
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.
