My gauge isn't working. So I pulled the sending unit out of the tank, then lifted the arm and it registered full at the gauge when I dropped the arm, it reg, empty. The arm was free, so would that mean the end has a hole in it?
Don't know - can't see it. Take it off and see if it floats. When you removed the sender, did you disconnect the ground wire? Does the arm move freely?
i would double check the wire connections to make sure, could even be a broken wire inside the insulation........ you may have helped the wires make contact when you lifted it up to check it.
The float is a solid block of bouyant material. It could have a hole drilled through it (as it already does for the swing arm) and it would still float. However it may have become "fuel soaked".
