I'm not sure if that's the proper terminology but that's what I call. Has anyone ever had a problem when filling their car with gas? It doesn't seem to matter which station or brand of gas when I try and fill my car the nozzle immediately shuts off like the car is full. I usually have to depress the handle at only 1/4 of it's speed in order to put any gas in the car. I've tried backing the nozzle out slightly thinking it may need more air in the neck but nothing seems to help. I live in Canada and in the winter especially it can bemore than a little frustrating when it's colder out.

Any ideas?

Thanks.

 

On a lot of cars these days a gauze is fitted in the filler neck to help prevent syphoning. It is possible that if your car has one of these it may be partly blocked.

You can check to see if there is a gauze fitted by gently pushing a piece of hose into the filler neck. If the hose stops before it reaches the tank then a gauze is fitted. To unblock it you will have to take the filler neck off and back flush it/blow it out.

I don't know what it's like to do this on your model, I've never tried, but if you're fairly handy with a spanner and a screwdriver, I shouldn't think it's too difficult.

Best of luck,

Chris.

PS. Alternative is just to continue your slow fill!!

 

Depending on the filler tube design, the flow from the pumps can be too fast to fill up cars. A standard pump runs 11-13gpm providing the pump filter is in good order. Some pumps can run at 15-16gpm. When the fuel exits the tip of the nozzle and is forced to go into the cars filler neck (which has a quick bend downwards toward the tank) the fuel will backspash a bit and the nozzle will think that the tank is full and shut off the flow.

Next time the nozzle shuts off after you've started fueling, pull the nozzle out 0.5-1.5" and then fuel the car. You shouldn't have any problems after that!

 

Just an update.

I checked out the gas vent tubes and found them to be free, dry and clear. I moved on to the charcoal canister itself and once I removed it found an electrical connector disconnected. I'm assuming this is some kind of assist for ventilation. The car was pretty well on empty when I was monkeying around so I headed to the gas station and threw $20 in it the the pump going full tilt and it didn't choke out once.

I drove the car back and forth to work today and didn't notice any difference in gas mileage or performance and decided to fill the tank the rest of the way. It filled without a hitch.

I have to get a manual for the car one of these days.

Thanks everyone.
