Hi Tim, Cant seem to get a straight answer on which post is hot. I suspect now that there is a short in the wire from the tank to the gauge causing a problem. I will pull the bed wood tonight to access the tank (48) Still not sure exactly which post to put the wire on a 12 volt gauge. Some say E side some say F side. I will work out the sending unit issue and then try again. Classic parts are out of gauges for now. Guess I cleaned them out! LOL The truck had ugly autometer gauges when I got it and I would like to put it back to a more classic look. Have had really bad luck with the old style gauges and speedo. This is the last attempt. after this I pop for Dolphin gauges.
