A Ghost these days...
I got to the track with a little over a half a tank of diesel. I make 2 runs then back it up to the fence, sit on the tailgate and drink Beer and watch the races for a couple hours. While driving home, my fuel gauge starts climbing ever so slowly till my truck is eventually FULL. I have nothing else out of the ordinary. What would cause this? the next day, I go put $55 worth of Diesel in it. Now my gauge is permanently stuck on full. HELP.
