Service Fuel System Light
I have a 2007 C6. My service fuel system light keeps coming on along with low fuel light. Even though I have a full tank. I have run two bottles of Chevron Tech injector cleaner through the fuel system. Still same issue. This is my first vette and I'm freaking out digging it so much. But this issue really is irritating.. Thoughts??

After you drive for 50 to 100 miles does the system go back to normal ?. If so, run it down to a quarter tank or slightly less and add a
Bottle of Techron Fuel System Cleaner and fill it up. Do this at least twice and report back with results. Sulphur buildup on fuel sensor. Running it down will make sure to get Techron into both tanks.

He literally just said he had done that.....
Worst case you need new fuel level sending units. The car isn't going to stop running or leave you stranded for this issue, assuming you don't run out of fuel (obviously
)

Injector cleaner and fuel system cleaner by Techron are two different products. 1/4 tank or less will get it into both tanks when you fill up.

Post #4. Let it get down to 1/4 tank or less. Pour in bottle fuel system cleaner. Then fill up. You may have to do this more then once. Report back after. once per fill up.

go to your tuner. ask him to uncheck the boxes that trigger the MIL light on the sending units. Your gauge will go back to operating normally and no more warning messages.
Then forget about it. did it to mine years ago.
