Before I took it to the dealer, I would remove the control panel and move the black tank sensor wires to a gauge from a gray tank and test. This way you could determine if it is a bad gauge or wiring/tank sensor issue. I find it easier to diagnose the problem and then tell dealer what needs fixing. I don't even use the black tank gauge because it isn't accurate anyway.
