There are several posts on fuel gauge problems.
I fixed mine by only running the top tier gas in it for 2 tanks no problems in 6 months.
Some have said run a can or two of Techron thru it or a can of Seafoam with a half tank of gas.
I have a friend who runs whatever gas is cheaper but his car is still under warranty and he has had both sending units replaced twice under warranty.
