I have a '66 short step and I am customizing it quite a bit. I took the gas tank out of the cab and bought one of the PE tank kits from Jim Carter. I got it all installed and with the tank full, half or almost empty it will sometimes read full, sometimes almost empty at the gauge. I am wondering if I have a grounding problem, however I am also wondering about the ohms. I think that the '66 should have a 90 ohm sender and that is what is in it.. Any ideas?
