Fuel gauge problem solved
I've fixed the problem with the fuel sender / gauge. One of three things done seem to have cured the problem. First, I removed the fuel pump / sender assembly and repositioned it. The feed hoses sit at about one o'clock. I noticed that if i moved the unit before the retaining ring was threaded tight, it would affect the gauge. I'm assuming that the float was fouling the side of the tank. I then made sure that the unit was pushed in far enough to make an audible "snap" when it was in place. Second, I made sure that the threaded retaining ring was really tight, and the access panel cover door was positioned to not hit the sending unit plug. I noticed that if not positioned correctly, the cover would hit the top of the plug and push it down. This was accentuated by over tightening the panel cover when it was being put back on. This cover has a rubber gasket fixed to it that is fairly squashed, on my truck, so it's probably flattened on most older vehicles. Third, I thoroughly cleaned both harness plugs with electrical contact cleaner. This would be the one at the sender as well as the one located in the left hand rear wheel well. The gauge is now accurate, and stays accurate.It may be worth addressing these items when a fuel pump replacement is done. Now, on to the next headache, fuse-able links....
