Help
I tried to view the link posted and it didn't work. I wanted to read up on this strange issue with C5 gas gauge and the Techron cure. Was is in Techron that fixes this issue?

It's supposed to be the Techron.
For some reason, in these cars there's a build up of some sort (sulfer I think, but that just doesn't sound right) on the electrodes on the sending unit. Techron is the only thing "supposedly" that can get rid of it.

WOW! Thats sounds fishy to me Sean, if I remember right, gasoline is a solvent. Mmmmm... That's why I wanted to read that posted link to see what it saidand figure out WTF? I'm not saying Techron doesn't work, just seems very odd to me. I guess I'll have to research Techron. Thanks for the info Sean.

My understanding is the sulphur builds up on the sending unit and Techron in the Chevron gas dissolves the sulphur deposits.

Corvettes are not the only thing this happens to. My daily driver Japanese car has a similar issue with the gas gauge sending unit and Techron is one of the possible fixes other than replacement.

My Dakota has the exact problem.

Neither the GMC or Dodge has this problem. The Dodge has a whole slew of others, but not this one.

Well, my Dakota fuel gauge is fine when started and after about 15 minutes the gauge bounces from full to empty and everywhere in between. Here's a Link to the Dodge problem.

In your case it's ice in the tank not sulphur. Try a little antifreeze in the tank

Rustangs have this problem also as they use the same sender as the Vettes do.

FYI, guys... I'm a long-time Infiniti / Nissan guy, and the Q45's had this issue too.
IIRC, the "active ingredient" that Chevron calls "Techron" is actually a very dilute version of a product licensed by BG.
A couple cans of BG44K should then, theoretically, be quicker (and maybe cheaper) in the long run.

i see this issue in other cars but for some reason it appears more prevelant in c5 vettes. the way i start off is there is actualy a pcm updated calibration for some c5s, so the first thing i do is to reflash pcm with the latest calibrations then to sudgest chevron and techron, give it a few weeks and a few tanks and see how it goes (as of yet only works on 1/3) if the problem is still there then i get into testing the siphon pump and level sensors, i have seen level sensors with some kind of deposits and wear and in some cases the bottom of the right tank has an upward bow to it preventing the sensor from reaching full droop also causing incorrect sensor data. the replacement part has been redesigned to help prevent this issue.
