My 2003 Hyundai Elantra is very difficult to fill the gas tank. Keeps shutting off the pump filler nozzle & spitting gas back at you! DEaler replaced valve assy. in the filler pipe (first time) had to take it back then replaced canister in filler pipe- said it was froze-up (clogged ??). So far spent over $ 1,000. Still not right!! Help!

The fill tube for the fuel tank is either clogged with something or the anti-siphon feature (what stops people from stealing your gas) is fouled up. The tank and fill tube have to be inspected.

There is an emissions unit underneath the car by where your gas cap is. It's job is too collect the fumes when you fill up the tank and once the car is started and certain parameters have been satisfied it sends the fumes up to the engine to be recycled. If it is worn or plugged up or the hoses are kinked the fumes cannot escape the filler neck and will cause the fuel not to flow into the tank properly. Air bubbles are coming up the filler tube while the gas is trying to go down.
This item is covered by warranty mandated by federal govt.(if you are in the USA). If they are unwilling to fix this under warranty you will have to contact Hyundai first :
Hyundai Motor America
Consumer Assistance Center
10550 Talbert Avenue
P.O. Box 20850
Fountain Valley, CA, 92728-0850
(800)-633-5151
If they cannot help you, then Contact someone at the FEDERAL CLEAN AIR ACT. which states that certain emission parts have to have an 8 year/80,000 mile warranty no matter what the manufacturer claims.

hold filler nozzle back a bit and hold trigger halfway in

When a gas pump does this it is because there is alot of pressure in the gas tank. This is a good thing for you because it means all your seals in the fule system are working good.Next time you fill up open you fule cap and let the car vent for a little bit then try to fill.

I have a 2005 Hyundai Accent, It is not possible to fill the tank if you are letting the petrol pump run at full speed.Trying to fill up quickly it will only build up pressure and cut off. Next time you fill up just pull the petrol pump handle half way, it will take longer to fill but you wont get the blow back. Modern petrol pumps are getting quicker all the time.Hope this helps you.
