NOTE: The retaining fuel sender assembly will spring-up when the retaining ring is removed.

Remove the fuel sender retaining ring using Fuel Sender Lock Nut Wrench (J-39765). 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. When removing the fuel sender assembly from the fuel tank, the reservoir bucket on the fuel sender is full of fuel.
The fuel sender must be tipped slightly during removal in order to avoid damage to the float. Place any remaining fuel into an approved container once the fuel sender is removed from the fuel tank. Remove the fuel sender assembly. Clean the fuel sender sealing surfaces. Inspect the fuel sender sealing surfaces.
