Hello all, new member to this forum and first time poster. Recently purchased a 1997 obs 7.3 and it has become my new daily driver, and so far i'm loving it! However I'm having an issue with my fuel gauge fluctuating or going past the full mark when i'm switched to the rear tank. The front tank reads normally on the fuel gauge on the dash with no problems, it's only the rear tank. Usually when the tank is full, it'll read well over the full mark, but as i drive around it will fall back below full but the needle will jump around to full or half full or 3/4 full, and sometimes it seems to act "normal" but i'm weary to trust whatever reading it gives me. I've read a bit about different problems with the sending unit, or the fuel float, or wiring, but haven't been able to locate someone having this same problem. What do y'all think? Any help is greatly appreciated!
