I've had this problem and no matter where I took my 2000 Hyundai Accent, the fuel would click off on max setting. I took it to a shop and told me to remove the lines on either side of the fuel intake. I removed the one on the right and it filled like new. Replaced the line and the fill went to a crawl again. I removed it again and it filled like new again. So I kept that line off, but wonder if something on the fuel neck is blocking ventilation out. How would I go test this theory?

 

As you look at the fill neck, remove the right most vent line. If it fills like normal, that's the line with trouble at the neck. Not sure about the other line though.

I wish I knew how to figure out what is causing my 00 Accent to keep clicking off when pumping fuel into it. Replaced the charcoal canister, but it still fills slowly and someone saw the filler neck is cracked. It had a nice puddle for the car sitting from 4:30 pm to 7:30 pm. How easy is it to replace the filler neck and do I have to drop the tank?

 

Any idea where the fuel filter is, if it has one?

 

I had the same issue of the gas nozzle shutting off frequently when pumping gas in one of my three Elantras. I pulled the charcoal canister and, like others have reported, found charcoal pellets clogging the larger evap hose. Looking into the canister through the openings for the hoses I could see that remnants of a foam filter that was falling apart and letting the pellets migrate into the hoses and clog them. Once I removed the wayward pellets, the fix was simple - I found some light foam that passed air easily and stuffed it in the canister openings to keep the pellets contained in the canister. Now the car gasses up fine.

 

a little presure is the best way to get must of the pure fuel.... less bubles and air and more fuel

 

I just got a 2015 Hyundai Accent with only 40,000 miles on it, and it’s also having this issue pretty severely. 😒 sounds like maybe I can take care of it though

 

There is one thing that has a lot to do with filling the fuel tank.
That is ,,,,,,,,,not stopping putting fuel into the tank when the nozzle has shut down. This starts out when the topping off until the tank will not take any more fuel.

The Evap system is designed to collect "Vapor" only. When over filled liquid gets into the vapor system and destroys the canister and clogs the lines.

If the present or previous owner did this , the system is on it's way to trouble. This is how it starts and then progresses , it never gets better once the damage is done.
Cleaning lines and canister replacement are the fixes. There are vent valves that can malfunction due to internal function and filter clogging and those need to be checked out also.

 

I watch the u tube videos about this problem. And it seems the canister and valve are the problem. I was wondering if i just disconnected the vent tubes if that will work for now. Also wondering if that will trigger a check engine light. Anyone who could give me advice would be appreciated. Thanks
