fuel gage sending unit inside the fuel tank
Chevy's are known for this problem, i just recently had the same problem and what you need to do is replace the fuel sending unit. My original problem had to do with my fuel pump not working and i wasn't really worried about the gauge but we figured since we had the tank down we might as well swap the sending unit and my gauge starting working. Good luck
