My fuel gauge is pegged on Above FULL. I had a 1/2 a tank, so I went to add gas just to be an the safe side. It just kept pouring out the top over flow no matter how slow I attempted to refuel

. And I know darn well $20.00 wasn't going to fill it

let alone over fill.
When I start the engine the fuel gage goes to full, backs down to empty, and then to Above Full reading and not to the exact fuel level
Any Ideas
