4. Use the J 45722 and a long breaker-bar in order to unlock the fuel sender lock ring.




Important: 

•	The fuel sender assembly may spring up from its position.

•	When removing the fuel sender assembly from the fuel tank, be aware that the reservoir bucket is full of fuel. It must be tipped slightly during removal to avoid damage to the float. Discard the fuel sender assembly O-ring and replace it with a new one.

•	Carefully discard the fuel in the reservoir bucket into an approved container.

Important:
