Are you having trouble with the sending unit (a replacement sending unit?) reading accurately? If so, take a look at the encased re-o-stat part of the sending unit from the side...there should be a small hole on each side. Look through the hole as you lift the float arm through its throw. You should see the re-o-stat connector (a piece of wire about the size of a coat hanger) pass the hole as you raise and lower the arm. If your gauge is reading low, stick a scribe, metal coat hanger wire, or anything else rigid through the holes before the piece passes the hole on the way down. Once it comes in contact, move the float down about another half inch to an inch, then remove the wire and re -install into the tank. Obviously go the other way if you 'over reading'. You may have to try this a couple times to get the gauge to satisfactorilly read on the full and empty ends. I adjusted mine twice. It now goes well past the 'F' when full, but is rather accurate when in the 1/4, to 'E' area. Looking in the 'hole', I moved mine a good 1/2" total from its original setting, which would never go much above half tank new out of the box. Hope this helps...you or another member having rouble with their gas gauge reading.
Silly question: You do have the grounding clip (strap) that goes from the sending unit tube (jumping the rubber hose) to the hard line that runs up to the engine, right? Just checking.
