After reading your posts and checking an old post from 2016, i disconnected the connector at the firewall (502 I think) and tested there. The guage works properly. I then cleaned the connector and reconnected it and the guage reads just barely below full with about 10 miles since i filled the tank. Before testing it read way above full. I'm thinking that the connector was dirty or corroded a bit. Guess ill see when I run out of gas.
