Gas Gauge erratic...
I'm sure this is discussed somewhere, but I couldnt find it... My 99 vette, 25K miles on it, is having trouble with the Gas Gauge and "Range" in the DIC... I filled the tank to the top, and the thing went to 0 for both the gauge and the Range in the DIC... In time it started to creep back up... Has anyone else had this problem, and what was the solution and cost? Thanks in Advance...

Use Chevron gas. Right now-go to Auto parts store and get a bottle of Techron and pour that in. I have never had a problem with my gas guage after using only Chevron gas.

You might want to check the following thread that is going around in C5 General: Gas Sensors Question.
Good luck.

Your right tank fuel level sender is probably dirty. It’s common problem. Techron helps clean it. The way most cars work the sender is submerged in gasoline almost all the time. The way the Corvette fuel system is plumbed the right sender is only submerged in gasoline until the fuel level goes below ½ tank. Then the right tank is empty and the sender is in gas fumes only. The sender is not too hard to clean. If you clean it you will see the problem. The resister will have some build up on it causing some of the windings to short out and cause an incorrect output. Do a search on fuel sender and there should be a procedure on how to get to it. A pencil eraser and some contact cleaner work well to clean it. If you use techron make sure you have at least ¾ of a tank of gas or you won’t get any techron into the right tank. My experience is that techron works somewhat but cleaning really works.

Senders...plural...located in the gas tanks (C5's have a saddle style tank).
Welcome to C5 ownership...mine drops to E at about 1/2 tank...I am going to take it in one of these days to the dealer and have them replace the sensors before the extended warranty expires (GMPP).
