Again been many years since I have had to do this, as years ago good used sending units were about 5 to 10 dollars each and everyone wanted to unload them. Worked on many cars and I seem to remember doing this once. What you can do (I think) if you have enough clip leads or wire. Is, bring the sending unit to the front seat, where you can connect it up as if it was in the gas tank, but with you looking at the gauge. The gauge acting as the ohm meter. Now you can move the arm up and down, and sideways slowly to see if you have any open spots. It doesn't take much. Or if the wiper is lifting off of the wire. Or if you have an extra battery and gauge you can do on your bench. I seem to remember opening one of these up at one time. It would have been for a prewar senior model. I think I remember bending the wiper just a bit to make up for sideways slack in the arm and bushing. Burnishing the contact with a piece of business card and some sort of solvent, probably brake parts cleaner, but not for sure. Then I believe this unit used a couple of rivets to put the top back on. Also just thought, make sure the arm is not hanging up on only one position.
