Filled truck up with fuel and fuel guage stoped working

There is a TSB for this issue ( TSB 08-2-9 ).

The problem is high sulfur content fuel will cause a problem with the fuel level sending unit, and cause it to read incorrectly.

The 2 times I had this happen, I was not at my normal brand fuel ( had it happen with Shell fuel both times ).

I fueled at 1/2 tank with my normal brand, and then after another 1/2 tank fueled again, and the problem went away.

If you want, the TSB lists new revision fuel level senders, that you can drop the fuel tank, and replace your exiting one with to cure the problem.

The correct P/N depends on your truck cab & bed config, and options
