Do the same to the bad unit, chances are, the needle won't move when you move the float arm.

EDIT: 8-12 ohms full and 70-73 ohms empty.
On the pull and pay sending unit, the ohms are within tolerance. I'll have to lift my bed a little bit to get at my old one. Is there a way to replace just the rheostat, or is it easier to do as a complete unit? Also, I want to put a new filter screen on, but not sure how to get the old one off. Don't want to damage it. Thanks.
