I have a 2000 Hyundai Accent. Whenever I go to fill up my gas tank, the pump clicks every minute or so (like it does when your tank is full). Is my float stuck at full? How do I get it unstuck?

Kaylie, try letting off on the gas pump trigger a little and pull nozzle out of fill port approx. 1/2", this will normally slow the flow rate of pump down and let air behind gas and stop shutting off. Some pumps are just set to pump too fast/ too much volume. If this does not work for you, have a Tech. check and see if there is some other restriction,plugged vent or problem with the vapor canister. Check the attached links,instruction and guides, Good luck

My 04 Avalanche will not let me fill the gas tank as the fill nozel keeps shutting off as I have now tried to fill at 4 differant pumps. Yes the tank is near empty but I can hear the gas coming up the fill...

Is there a check engine light on? The first thing I would do is look at the vent solenoid. GM has had issues with these either sticking closed or the filter getting plugged.

Find the charcoal canister. It will be mounted near the fuel tank. There should be a large hose attached to it. On the other end of that is is the vent solenoid. Remove it and see if you can fill the tank.

If you can than see if you can blow through the vent solenoid. With it unplugged you should be able to blow through it easily. If you can't than it is broken and needs to be replaced.

I beleive GM has updated the part and routing for that year. You can check with the dealer to see if that is the case.

Is it because of the configuration of the fuel pipe that the auto shutoff doesn't work at the gas station?

Auto shut off on gasoline pump works on back pressure. If the nozzle itself is "kicking off" early, it could either be a bad nozzle or that the vent system in your vehicle isn't working properly. if the pump itself isn't shutting off, that is a problem with the pump, not your car. Some nozzles will work if held at a different angle or if they are not shoved down too deep into the vehicles fill neck. Problem in the vehicle is usually associated with a bad evap system valve as generally nothing happens to the vent line on the tank to the fill unless you had an accident.

Gas pump keeps shutting off when fueling

you have a vapor vent issue. The fuel filler pipe has a vent inside of it to let out air as you pump gas in. If no air comes out, it will kick of the nozzle
The other possbility is that it is a poor design and others are having issues too. Cal your dealer service manager, not a service writer and ask him if there is an issue. Write or email Chrysler and ask them too. If the fuel filler pipe has a sharp bend and goes up hill at all, that will back up the fuel fill. Try putting the nozzle in upside down & see what happens. Also, try inserting the nozzle just a couple of inches. Report back please.

Fuel Fill Problem-Lexus RX300


Yes....this does sound like a kinked or restricted vent pipe.

Has it been like this, since you bought the car ?

Did you mention this whilst still under warranty ?

Have you ever had any accident damage or repairs in this vicinity of the vehicle ?

I suggest you go back to your main dealer and try to get this rectified under warranty, as this is a potentially hazardous, and dangerous fire problem.

Due to the temptation not to fit the pump nozzle fully in to the tank spout, to speed up the filling procedure.
And possibly then a blow-back of fuel, over yourself, and then the fire risk.

Lexus normally have a very high standard to maintain, especially where safety is concerned.

Get an appointment with the service manager, and do not be fobbed off.

$2OOO. sounds a ridiculous cost to rectify this problem.

Let me know your thoughts?

A FixYa rating would be appreciated.... Thank you !

Good Luck !

you have a vapor vent tube problem. When fuel goes in, the iar must come out. The filler pipe has a vent pipe inside it. Try putting the nozzle in upside down & see what happens. Try putting the nozzle all the way in & see what happens? Try putting the nozzle in just a little way & see what happens.
Otherwise, you may need a new filler pipe.
