Twice my fuel gauge has rotated past Full. Today I went to a GM service dept with the gauge reading at 5pm when it should have been about 3/4 full. They did a diagnostic and advise the cluster of gauges had a problem. When I got back in my truck the gauge now read 3/4. I stopped and filled the tank and it is now reading full as it should. Service manager advised to drive it and see if it fails again and if it does we all know it is going to cost $513 to replace the cluster with a re-manufactured cluster with a short warranty and labor, all costs $513. I don't understand how hooking up the test equipment could reset the or have the gauge show the right fuel level. I love my truck and plan on keeping it for another 5-10 years as I only put on 5k miles a year and the truck has 60,000 miles now. Should I wait to see if it fails again or go ahead and get it replaced for $513.00. Confused on why the gauge changed by them testing the computer. thanks, JJ.

Problem is likely to return .. It's a pretty simple task to remove the instrument cluster .. You can have it repaired for a VERY reasonable price .. Google > 04 GMC savanna instrument cluster - check out the results page .. Save yourself bout $425.00!
It's probably an intermittent problem, so it will come and go at seemingly random intervals. It is probably a coincidence that it started working again after the dealer diagnosed it.
