Happened a few times, I would go to pump fuel into my car and after about a few seconds the nozzle would stop. What usually happens is the next day it wil fuel up but what is the cause? Gas station's end? My fuel sensor? What?

I drive a 07' auto NA. Gas is premium 93 rating from Chevron.

Thanks.

Do you always gas up at the same station? At the same Pump?

Chances are it's the pump nozzle.

Disclaimer: At least that is my experience.

Who Knows? :dunno:

Same station - yes (I try not to pump elsewhere)

As far as same pump goes.. I don't think so. But very now and then the rotation forces me to use the same one :)lol:) but the thing is, I would (and did today like the other days) I would drive around the station to another pump and try it, still no luck.

It didn't accept it this morning, the reason I asked so abruptly was because I'm about to go attempt again before I go out... By the way it happens around (guessing) the 1/3 fuel remainder mark on my gauge, but as you all know the gauge is quite glitchy itself. So...

Try pumping slower, try changing the angle of the nozzle going into the tank, try pulling the nozzle out a bit or pushing the nozzle a bit further in.

Air lock in the filler neck. As Dave says, pump slower or turn the nozzle in the neck, even pull it out a bit. You'll find a position that lets the fuel go it without bubbling back and shutting off the pump.

Rereading Dave's response, I realize I didn't need to write this. Oh well.

From how things work:

As the gas level in the tank rises, the distance between the dispenser nozzle and the fuel grows smaller. A small pipe called a venturi runs alongside the gas nozzle. When the end of the venturi pipe becomes submerged in the rising gas, it chokes off the air pressure that holds the nozzle handle open and shuts down the flow of gas. Unfortunately, this shutdown can sometimes happen before the tank is full as the rapidly flowing gas backs up on its way into the tank. This can cause the gas handle to spring open before pumping is complete, leaving the annoyed customer to squeeze the handle again and risk the possibility of overflow. Pausing briefly will allow the gas to continue into the tank and the pump nozzle to start pouring gas again.

I remember a warning in some old auto manual that accidentally dipping the end of the nozzle into snow could block the venturi tube. Of course, so could a smart alec kid.

The pump cuts off when the senser in the end of the nozzle sees back pressure. Either the sensers are too sensitive, or there is some strange problem in your fuel system creating back pressure.

I think it was what Dave and T.S. suggested, me pumping too fast. I tried it again, tilted the nozzle a little and slowly pulled the trigger and it worked... let's hope it doesn't happen again, or could be what Rob said, a sensitivity issue.

Thanks for the detail GrandpaSolstice. We all know pumps shut off when reaching the liquid, but that explaination went through my head. Haha

Thanks everyone, glad to fix/learn so much here rather than spending money! :)

I have never had any issue like that with my coupe. Might be the pump ( does it happen every station you go to? ) or something is creating backpressure.
It's only happened a couple of times, less than 10. I believe it was because I would push down on the nozzle trigger too hard or not enough (just barely trying to get it in automatic pump with the slowest speed). Also me inserting the whole nozzle as far down as it would go (because the dam last drops fall near my fuel cap and on my car's paint :brentil:).

Perhaps you need a bib?

Let me google that for you

My son bought this for the Solstice for christmas 2005. It just clips on around the fuel pipe. It's die cut out of a sheet of rubber-like material. It folds around the fuel cap after you tighten the cap.

The bibs are only $6.95 at Rodney Dickmans.

My 05 Elantra did that. Mostly when the tank is closer to empty. I tried to move the nozzle around to find the sweet spot but it still did it. sone pump nozzles are more sensitive than others. I tried pulling it out a but and it still did it. however, once the car is over half full, the problem goes away. you just might have to pump it in slower at first and don'e let it get all the way to empty.

With over 7+ years of having a Sky NA, yea I have run into sensitive nozzles, however, I have never had gas barf out that required my sky to have a "bib"...
:lol: I guess my "baby" knows how to eat its meals normally...;)

Well I try not to ever let my car run on less than 1/3 gas ever. The most I've ever refueled was about 8 gallons so that's roughly 0.39 tank full, (~8gallons/~13gallons), just above 1/3.

And the bib... I think it's the nozzle because I let it sit there for like 10seconds, then I raise the end so it can drip more into for another 10seconds then I slowly remove it.. A good 30 seconds removal and it still manages to drip 2-3 drops on its way out.

Easy fix: turn the nozzle "upside down" as you remove it from the filler pipe.
