mine drifts up to 7/8 of a tank every time i shut the key off. It does this really slowly. I think this is just part of the personality of the truck though because it seems everyone's does something different. Maybe go by something else to determine if the gas gauge is good? Maybe try grounding the wire and confirming the gauge goes to its max or minimum? I'm not sure if that's bad for the gauge or not though. So be careful.
