Rep Power: 902

My car sat up for about 2 weeks because of hurricane Rita. Once I got back I started driving my Z28 on a daily basis, right before the storm I filled my tank and added some fuel injector cleaner to the mix. When I got back I just drove my car back and fourth to work (less than 5 miles round trip). Well, recently I have noticed my gas gauge is becoming a little erratic but at the same time sloshing in the tank can cause these gauges to bounce wildly. Well, a few days ago I turned my car over and my needle went from a little above the half way to past F and then came back down. I went and put $20 in my car yesterday (needle went to F) and now I have put about 50 miles on my car and the gauge shows I have burned a little more then a 1/8 of a tank. Does it sounds like my gas gauge shot or am I overreacting here?

could be the gauge, could be the sending unit, could be the float, could be nothing...hope that helps

sounds like a gm fuel sending unit, every mid 90's gm vehicle I've owned, or my family members have owned have had to replace it (there is a class action law suit pending, but at most you'd get about a nickle from it)

Thanks for the info. I was just kind of spooked cause the way my gas gauges spiked for no reason when I started my car. It has never done that before.
