My gas gauge on my 95 z28 reads past full when it gets down to half a tank
tank is really empty wondering if anybody had had this same problem and how to fix it

 

Does the gauge EVER read less than "past full"?

Its normal for the gauge to read past full until 3 or 4 gallons are used, then to gradually drop to "1/2" when approx 10 gallons have been used and only 5 gallons are left. If your tank is empty, and the gauge never moves off of being above the "F" level, the level sending unit in the tanks is faulty, or the wiring from the tank to the gauge is damaged.

Shoebox has info on checking the tank level sensor:

Thanks for the link Ima try the different ways that they have posted to test it
