Have not fixed the gas gauge that is reading incorrectly. At this point I think that I have to drop the tank and get to the sending unit. Can't seem to be able to ground the gauge out but will try a couple of other things before dropping the tank which is a real project. I did put a jumper wire on the gauge connection which causes some resistance, but does not seem to fix the problem. Tried running another ground to the tank but can't seem to find a good connection there. Getting at the gauge itself requires you to be a contortionist. More to follow as I keep working on this.
