Yes my wife's elantra has the same problem

 

The little spring that holds the flap closed may have broken or the flap may have fallen off If you notice the filler pipe is quite small in a Hyundai and it could be stuck in there causing a restriction Good luck

 

Read the WHOLE thread. You missed this post:

 

Okay if the canister is shot what is the answer!
Can the charcoal be dried out or does one have to purchase a new one.
Apart from cutting the canister open is there a quick fix.

 

First is to disconnect the hoses from the canister and clear them out. If they are clear and it's still a problem then yes, you need to replace the canister.

 

Thanks for the input.

 

I got under the car today at around 10:00 and crawled out at about 16:00 .
Took the Charcoal Canister, fuel line assembly from filler port to petrol tank out, cleaned all the pesky charcoal chips from the lines was tempted to drop the fuel tank but thought better of it..
Refitted it all back together with a new $160 Canister took it to the garage and filled her up.
And it worked by heck.
It was only 86F in SW Florida today so not too hot.

 

Thanks to james92se for his posts above.

My recently purchased 2003 Sonata had the slow fuel fill problem discussed in this thread. I took out the charcoal canister - mine was a little bit different than james92se's - 4 hoses rather than 3. A fair amount of charcoal pellets were clogging the hoses (mainly the "To Neck" hose). I cut open the canister and sure enough, the filter material had disintegrated and was allowing the charcoal pellets to exit the canister through the hoses. I replaced the filter material, glued the canister back together, and re-installed it after the epoxy had cured. Was able to fuel-up at full speed on my first subsequent fill-up. I'm convinced I won't have any more charcoal pellets leaking from the canister. I'm hoping this has it fixed without having to pull the 'Fill Vent Valve (ORVR)' as discussed by BobQhy.

Again, thanks for james92se for taking the time to post such a detailed and informative write-up.

 

Glad to hear you took care of it


I'm happy to report that two years and 26k miles later my mom's Elantra is still trouble-free from this issue after my repair

 

Hi all. New here and the info has been great to read. I own a 2005 Sante Fe. I recently replaced the gas tank due to a leak (it rusted out).

Prior to the tank replacement I had no issues with filling the tank. I would set the nozzle to fill automatically and it would cut off when it was full. I wouldn't try to top up the tank more. Ok, maybe to round it up to the next dollar

After the tank was replaced, (August 2014) I have not been able to fill my tank to the top. It goes well no problem when I start to fill it. The issue is when the nozzle cuts off the fuel flow from the pump, about 1 second later fuels spits out.

Even if I control the pump myself, this happens. When filling up a tank, you stop once the pump cuts off. Simple. Except my tank now spits out once it stops.

I replaced the tank again in December 2014, and replaced the vent valve at the same time. No cure. Has anyone experienced this?

How does a new gas tank cause an over flow problem???

Thanks!


James
