Search the forum for "Techron" fuel additive. Lot's of info on this forum about your problem.

I had the same issue: Used Techron for 5 or 6 fill ups and the problem is history.

It is caused by high sulphur in gas (fuel level sensor gets dirty). Use Techron AND switch to a top tier gas, go to:

toptiergas.com

Very common problem... I run a bottle of Techron every 2000 miles to dissolve any sulfer build up on the fuel sending unit.. I only use Chevron 93 octane with techron... No more problems... If it gets real bad or is neglected for awhile the sending unit will have to be replaced because of too much sulfer build up

The other stuff that really helps this is putting a can of Seafoam in your gas tank. Since I did that over 6 months ago, no more problems.

There are various reasons why the fuel gauge can malfunction. Just like previously mentioned in this thread, in searching the Corvette Forum archives you will note that by far the most diagnosed reason is due to sulfur fouled sending units which are usually treated successfully with Techron, Seafoam, etc.

My fuel gauge issue turned out to be from a different cause. Fuel wasn’t transferring from the right tank to the left. The sending units saw the level discrepancy as an error and would cause the gauge to trip off. I fixed the fuel transfer problem and haven’t had a problem with the fuel gauge since.

Technically there are several possible reasons for faulty fuel gauge readings.
I hope your repair turns out to be inexpensive and easy!

Default cleaned the jet pump orifice

Hi Mike,

I cleaned out the orifice of the jet pump. There was no air getting through. After using a wire, now there is. Put things back together.

What do I do now? I put 5 gallons of gas in but still reading empty. Do I need to fill the car up with gas? How do I know if I fixed it?

Thanks

Wow!!!.

I got in the car this AM, the gauge was reading correctly. For the first time I had less than 1/2 a tank and it read that was. I drove around and got almost down to 1/4 tank and still fine. This thing hasnt worked in 6 months. All I had to do was run a wore through the little plastic orifice in the Jet pump.

Mike and Bill, Thank You so much for your help on this. Your information saved me tons of $$$$. I spent $25 for a pump and a pan to do the job instead of upwards of $2000 the Stealership wanted.

Thank You

Chevron, Shell, Texaco only going forward. Had the same issue over 4 years ago on my DD. Changed fuel selection, Forum info, and no problems since.

I have the same problem with my fuel gauge, but it is intermittent. I ran a tankfull of Techtron treated gas through about a month ago. I plan on running another through now. Do you guys think that it would be allright to leave a full tank of treated gas set in the tank all winter and would it be allright to put Sta Bill in with it?

Default Now mine is worse

My fuel gauge stayed towards the full side most of the time. I ran 3 tanks of gas with the Techron added and now it won't move off of full. The wife was driving it and it showed 385 miles on the trip odometer. The car started dying as I was on the way to a gas station. made it just in time. I had 1/2 gallon left.

Guess I will have to pull it all out and see if I can clean it. Running 3 tanks consecutively with the Techron added should not have hurt anything, should it?

Thanks,

Oaklands

You obviously have no clue how many times I and many others have discussed this subject. The reasons and best recommendations have now become a matter of record in the archived information available to all here and save a TON of re-posting and re-hashing this same subject over and over and also saves members a lot of time and waiting for answers too. My post was directed to the OP, not you.
Glad to help.
