Noticed something diff today...if you fill the C6 tank with gas on the 1st notch [lowest flow] the pump clicks off early, did that about 8 times, checked gauge and it was just a lil over 1/2 full, so I squeezed the handle all the way and it filled and the pump clicked off without overfill....Just some advise you might use....

 

No, I don't think so. It depends entirely on the nozzle and the vapor catchers. I've been pumping my C6 gas that way for 2 years without a problem.

 

I think you got lucky on re-directing the flow slightly when it finally stayed on. More info to ponder:

Hey Dude,

This happens to me too, you should only go for another gas station or use another nozzle, its from the nozzle .. there is nothng wrong with the car

 

When this happens to me since I frequent to the same gas station I hold the the trigger in place after the first click off and pull up on the gas nozzle and squeeze until I fill it to about 13 gallons on the meter from a empty tank. So I hold the gas nozzle at angle upwards.

 

No disrespect, but 22% of 2006 C6 owners reporting on this issue on the CF poll disagree with you.

 

That's funny that you mention this because I had the same thing happen yesterday. It doesn't do it at all pumps, but it does regularly at the one down the steet from me. I fill up my F250, BMW and Firebird there all the time without the same problem. Weird. I am not sure how the auto shutoff works on the nozzle.

 

 

I notice mine is way more picky than any other car I've owned. I get the early click off at gas stations all over the place. A minor annoyance I can live with, but it seems pretty touchy.

 

whether your car had it, or didn't have it, I would appreciate all responses to the poll on this subject in the link given above.

 

Is it possible that the pump clicks off because the filler neck is indeed full, the gas is just a little slow draining over to the other side tank? Give it a few seconds to equalize while we cuss the pump and squeeze the trigger again, then it can take some more.

 

Holding the nozzle up (rather than letting it rest on the lower part of the filler tube) has worked every time I have encountered this problem.

 

There's only one tier one station around me and its pumps don't get along with my car.

So I just count the number of fuel gauge hash marks that I'm down and add one less gallon than that amount, usually by repeatedly goosing the pump handle or squeezing it enough to get gradual flow.

It pretty much fills the tank and I've yet to have an overflow.

 

Can only speak for myself, but the rate of fuel flow when this happens seems unlikely to be filling any kind of 'cue' that then backs up -- in fact, leaving it to 'drain', and then going back to lowest fuel flow that the trigger will allow still sometimes clicks off -- that is what is so maddening -- seems to be not a volume or a rate thing, but more of perhaps a backpressure thing, with too much restriction in line some where...

Redirecting flow does often seem to have an effect, i.e. turning handle of fuel pump completely upside down while filling, but it certainly is not a reliable solution or even a workaround.

I kind of feel guilty even spending this much time talking about it, yet just yesterday evening I was filling up, and it was turning off constantly and I was cursing the car, wondering if perhaps some assembly technique just leaves a bit too much bend in some hose, or a few degrees too much angle in the way the filler neck relates to the fuel entry into first saddle tank... my take from the way it responds is that for me it is clear NOT anything to do with need to get fuel from one tank to the other -- it even happens when I am bone dry, it happens when I have a couple gallons in tank, it happens with half tank, it even happened when I experimented just needing a couple of gallons.

Thanks for ideas....

 

Mine has always been picky. I always hold the pump little higher, and only let it flow at a low rate manually, stops early then i try again. Seems to work after several clicks. Sometimes I get lucky and it flows with out any interuption. The other day I decieded to try it on "auto" at a slow rate of flow. Damn pump overflowed without clicking to a stop. Same station, same pump as before. Only thing I did different was not hold the pump higher, I let rest down in auto. I'm too afraid to try auto again.

Thanks for the detailed reply. Our C5 and now our C6 are a little "touchy" in this regard, but not to the extent where it's a big issue. I always use "auto" but the lowest flow speed on the pump. Perhaps one fillup in 10 the pump will shut off early and I just restart it, perhaps one in 30 it keeps shutting off until I reposition the nozzle or use another pump.
If only we knew why mine is so good...

 

yes, I've noticed that too. The darn gas nozzle keeps clicking off. I hold it up to get it going again...

but my biggest complaint is the gas cap itself. It has to be defective because it starts "clicking" when it just barely grabs one thread. Major pia because I'm never quite sure it has sealed before driving off.

 

Ratcheting/clicking action is on all of 'em now. Makes sure it has at least a minimum & consistent torque on it, but not so tight so that it damages seal or is impossible to remove later.




“Consumer misuse of the gas cap is also a source of evaporative emissions. This occurs when consumers fail to tighten their gas caps to the proper torque specifications allowing gasoline vapors in the gas tank to be vented to atmosphere.”

In the late 1960’s the Consumer Product Safety commission required that gas caps be designed with the familiar “turn until it clicks” design.
