techron works
Well , I had the same problem this month and sure enough,50 to 75 miles and a quarter of a tank later. The gauge popped right back up.
Can anyone tell me if the chevron gas solves this problem without the techron and if so is it regular unleaded or hi test.
Im trying to determine if it is cheaper to use the techron or sea foam rather than the gas and how often should you use a bottle of it.
I seen a post where someone used a bottle every 4 tanks. Is this with the cheap gas being used or the chevron?
thanks

I had to replace mine, and it was around $800.00 for the dealership, due to the 10 hrs of labor to remove the fuel tank, and replace the bad sending unit. A bottle of techron is alot cheaper.......

I'd say one every 4 tanks is excessive. Mind you it shouldn't do any harm. I cant get Techron here so I have a few bottles as a precaution. I've been OK for nearly two years now.

I have always used Chevron every fill-up for the past 8 years - still started seeing this problem after about 20,000 miles, been drowning it with extra Techron and Seafoam ever since (for about the past 4 years). Looks like the patch has finally stopped working for me the past two months. Wonder if this is covered under GMPP? ...of course I doubt the replacement parts would last any longer (just like the replacement Oil Pressure Sensors!)
It really is kind of amazing that every sensor that sends liquid pressure or liquid levels info to gauges has a chronic problem that was never fixed? The C5 is the best car I have ever owned (and the most expensive), but in 40 years I never had a gauge fail on ANY car (even my old 1960 Olds)! ...well I take that back, my 1985 Corvette with the LCD dash would go ballistic
if you ever got in the car with wet shoes, but it was temporary as soon as the floor mats dried out!

There was a lot of labor involved with dropping the suspension/tanks, and I think the total cost was about $2300 or so. But I had the $50-deductible GMPP, so thankfully it was not too painful on the wallet. Now I use Techron about every 4 or 5 tanks, it might be 'overkill', but my GMPP expires later this year, and I don't want to ever have to pay for that repair again.

I don't know if it is true, but one of the mechanics there said that they have replaced the old sensors with the sliders with a different type that has 3 gold contacts. He mentioned this when I said it may not do much good to replace them if they are just going to break again. He said the design was not a problem until gas quality started going downhill and that is why all the C5 sensors are crapping out. I still am not convinced that they have gone back and re-designed the C5 sensors to the newer type he is describing? Not sure how to find out?
