Typical GM. Anything older then 8 years..half will have it. Sending unit / gauge goes bad on a lot of GM trucks. It's easier to test the gauge, only because it's slightly easier to get to. Sending unit sits with the fuel pump. The pump, you can drop the gas tank to get to it, take off the bed, or just gas up every 200 miles or so and ingore the gauge.

Expensive for what it is, yes. If you get a shop to do it. The way I suggested is a way, but is time consuming. Fuel sending unit isn't that expensive, but like I aid, greastest cost is the work for the payoff.
