Either the gauge or the sending unit. Both can be checked with an ohm meter for accuracy. You will need a manual that tells you expected resistance.

The nature of the gauge is that it should behave with a linear taper between full and empty. If it works when full but then malfunctions as the level drops, the variable resistor in the sending unit which is housed along with the fuel pump in the gas tank is almost certainly at fault. The sending unit will have to be replaced to fix the problem. Expect this to be an expensive endeavor.

well the gage is made of rubber it could be sticking no other way than to replace the gage itself/ please rate my response thank you very much

Gm has a real problem with fuel tank sending units. That is what is wrong. You need a fuel tank sending unit. You can only get them aftermarket with the whole fuel pump module, but you can buy them seperate if you buy it from the dealer.

I had the same problem. My battery was going bad. When I replaced it with a new one, the fuel gauge worked fine.

Bad fuel level sensor. Unfortunately it is located inside the gas tank. Fairly common problem on GM's. Due to sulphur in fuel. Corrodes the sensor tabs. Expensive to have repalced and NOT a do-it-yourself project, unless you have dropped a tank before.
