(A) Pointer (B) Mounting Flange
Remove the two mounting screws for the fuel sender from the mounting flange (B) and save the screws.
Remove the fuel sender. If the assembly is equipped with an O-ring behind the fuel sender, remove the O-ring and discard the O-ring. Note: Removing the O-ring reduces the stress that is placed on the fuel sender. The reduced stress eliminates the moisture that may enter resulting from cracks in the fuel sender.
Prior to installing the new fuel sender, estimate the amount of fuel in the tank. If the tank is less than half full, position the pointer (A) on the dial to the left hand side of the 1/2 full indicator. If the tank is more than half full, position the pointer (A) on the dial to the right hand side of the 1/2 full indicator. If the tank is half full, position the pointer (A) on the dial to the 1/2 full indicator.
Rotate a magnet or a magnetized body such as a stem of a screwdriver at the back of the fuel sender in order to reposition the pointer (A) to the desired position.
Align the tabs of the new fuel sender to the mounting flange (B) .
Tighten the two screws to 1.81 0.12 N m (16 1 lb in).
