Fueling problems
2007 C6 Z51 Vert
This car is a pain to fuel! I came in to work this morning with the needle pinned on E. The check guages message in the hud was on and the Range was low. I did not think I would make it to the gas station. I started fueling and the pump clicked off at around 8 gallons. I pulled it again and it stopped again at around 13 gallons. After that I could not get it to take any more fuel. When I started the car the car showed about 7/8s of a tank on the guage. This is not the first time this has happened but it was the first time I ran the fuel this low. Anyone else have this problem?

When mine kicks the pump off it is full, not another 1/4 gal. without running down the side.

Some pumps have more sensitive shut off switches and diffferent back pressure boots than others. Try finding a different place to fill up and see if that helps.
It's better to avoid letting the tank get below a 1/4 full or so. The fuel pump uses the fuel in the bottom of the tank to keep the pump cool.

Page 6 lists some conditions which will cause premature fueling cutoff. If this is the first time this has ever happened, it was most likely the station pump. Just try a different pump. If it happens consistently then you have a problem.

Yes, filling at 1/4 is a good idea but it isn't as critical as it was on previous designs such as the C4. But if you ever run out of gas, DON'T keep trying to start it because you will destroy the pump.

Many more problems are gas station pump related than car related. But I will say, at more than one station, when the pump kicks off, that thing is FULL!

I think it was the station's pump being overly sensitive. The C6 is a pain to fuel, however. I've learned the hard way that once the lever clicks off because it's full, don't try to squeeze another drop into it.

happened to me once, tank was nearly empty. stopped to fill up, took only 8 gallons, I knew that could not be right so put in another half gallon before it clicked off again. Didn't dare put in more because I learned when it trips off, don't try to put in any more. I'm sue it was the pump because the next day, seeing the gauge still said half full, I stopped at another place where I managed to fill it up. Never has happened again.

The severity of the problem varies depending on where I go to buy gas. It's especially common at pumps in California. When on road trips elsewhere I don't seem to have this problem.
A workaround is to hold back the vapor recovery seal on the pump using your fingers. Just keep a close eye on the gauge on the pump, because it likely will not shut off in time. I sometimes have to hold it starting at around the 8 gallon mark, and release it around 15 gallons and creep up to the full-tank mark with only a light touch on the nozzle handle.

Although many have reported similar problems, I have never had any problem fueling my 2005 C6. I never set the pump handle at the maximum delivery speed...I always fuel the vehicle at a medium or low volume setting. As mentioned, fuel pumps and pressure settings can vary greatly from station to station and even pump to pump. Experiment a little and see if the problem doesn't improve.
Great information in the link you provided....thanks.

California pumps are the worst. I just have to be patient or lucky to get a full tank!

Vapor recovery pumps r bad
The vapor recovery pumps are the worst in terms of sensitivity but they don't smell!
Those are in at least: CA, NY, MA, CT, NH i think. others too.
The deal is the FLVV (fill level vent valve) is in the sub-side (passenger side) tank. The main tank fills first, 8 gal sounds right, and then the fuel reaches the x-over tube and wooshes over. The sudden air pressure increase can sometimes close off the FLVV.
Give it a few seconds to equalize pressure and you should be fine for another 8-9 gallons. Make sure you were really on E in the first place.
Second the post that said the pump will not overheat. The reservoir is full all the time and the pump is inside that. If the car is running the pump is being cooled.
