I just had my truck in the shop for 3 days to get the gas gauge fixed. They tested the sending unit (OK). Then replaced the dash panel still not dice. The gauge is always registering some amount of fuel towards empty unless you fill it up. If I fill up it will register close to full but the next time I start it up back towards empty. Any ideas?
Thanks.
If it's not the sending unit and it's not the gauge, it's something in-between the two. Which is to say a bad connector, wire, or chassis ground point. You start at the sending unit with a multimeter and work your way forward until you find the problem, one step at a time.

My mother's Camry (ex-Hertz car) had a similar story- multiple replacements of the sending unit, and the gauge (by Hertz), before someone decided to actually troubleshoot the problem instead of replacing parts and hoping. It turned out to be pinched wires under the rear seat, due to an earlier crash.
It was all covered by Toyota under warranty even though it was obviously due to crash damage while Hertz owned it, so top marks to Toyota and the Toyota dealership.
Could be the fuel level buffer unit. It should be stuck to the bottom of the glove box.
