Why does the gas pump hose keep clicking off while pumping gas?

My gas gauge works properly, for example it shows full tank, and it does go down as time passes. So i don’t think the problem is with the gauge. But whenever I start pumping gas, it keeps clicking off, in other words, when I begin fueling, the nozzle keeps shutting off over and over again. I heard that there is a “float” in the tank that acts as a “sensor” causing the pump to shut off thinking that it’s already full. Could there be a problem with the float?

I find that only happens to me at certain places when i get gas. Especially Sam’s Club. Might have nothing to do with your car and is a problem of the pump itself.

they cut off because of a vapour lock

The design of your ”filler tube” is a little restrictive. Try inserting the nozzle as usual and them pulling it out about 2 inches. This may reduce the ”back pressure” that triggers the shutoff.

No its called back pressure….when the pressure of the fluid is being pumped is somehow hindered by the narrowness of the fill tube and gas splashes back up and causes the nozzel to shut off….try pulling the pump nozzle out just a tad so the gas can go down easier….also, if you have to be told this I hope your driving with a license?

try repositioning the nozzle, maybe by putting it in further, or pulling it out slightly more before pumping. the gas pump has a pressure sensor, that senses the pressure buildup coming from the filler tube. it’s supposed to shut off the pump to prevent overflow but sometimes it just goes off easier on some cars.

it’s not the car, it’s in the pump. there is a shut off in the handle of the pump. when fuel starts to back up from your tank it shuts off. if you pump to fast this will happen because fuel does’t have enought time to get to tank, put nozzel on slowest possible fuel delivery this should help…

If pull back a bit on the nozzel in order to let some of the air escape while gas is going in. Back pressue is what causes the “clicking off” the pump. Be cautious not to pull it ouy to far or it may not stop and splash out.

To cure your problem don’t stick the nozzle all the way in the tank, put it in and then pull it back just a little so there is some air getting in and you won’t have that problem, it happens to everyone once in awhile so don’t worry about it.

the vent on youre tank is stoped up a small hose going from gas tank to filler neck you can get a new one from any auto parts house or you can disconnect youres and blow air through it or carb cleaner
