I have a 75 gmc k20. I've posted before and this page has helped me many times I'm hoping for another miracle. Fuel gauge reads way past full when the ignition is on and about 3/4 with the ignition off. The truck used to be dual tanks but the passenger side tank and valve was removed before my time. The switch for it is still in the cab I just leave it on the left hand tank. I've read other posts and the ground at the sending unit is good and I have 12 volts on the pink wire at the switch. I'm just not quite sure where to go from here. Hopefully someone can help thanks.
