I have been trying to figure out what's wrong with the fuel gauge on my 59 CJ5. It typically reads 1/2 full when its empty, and pegs the needle when its full. If I remove the sending unit from the tank and let it hang free, it reads 1/2 tank so its not float adjustment. I have replaced the sending unit, the ground wire, and the wire to the gauge. Nothing changes. By process of elimination, I plan on replacing the gauge next, but thought I'd see if anyone had any advise before I do. Thanks.
