Problems with filling up gas
 

Hey guys, my wife's 2002 Hyundai Accent is having some issues at the gas station.

Whenever we try to fill gas, the pump stops after about 5 seconds of pumping - no matter how empty the tank is. The pump only keeps going if there's very little pressure on the pump lever, just enough to get the gas flowing.

So, it would take about 15 min to fill up an empty tank like this.

Has anybody had this problem? Is there a solution?

Thanks in advance.

Found this reply from a previous post concerning gas fill-ups.
"Depending on the filler tube design, the flow from the pumps can be too fast to fill up cars. A standard pump runs 11-13gpm providing the pump filter is in good order. Some pumps can run at 15-16gpm. When the fuel exits the tip of the nozzle and is forced to go into the cars filler neck (which has a quick bend downwards toward the tank) the fuel will backspash a bit and the nozzle will think that the tank is full and shut off the flow.

Next time the nozzle shuts off after you've started fueling, pull the nozzle out 0.5-1.5" and then fuel the car. You shouldn't have any problems after that!"

Sorry Frozeh2o,

I have the same issue as "vchengap" with my 1999 Hyundai Accent and it didn't start until about November of 2006 (I have had my car since it was new). All of a sudden? What is that about. It was actually accepting gas from about March until mid-April when the problem started again. I go to all different gas stations and the problem was pretty consistent irrespective of the gas station I went to. I don't know what is up. I am definitely too cheap to take it in to get looked at, especially since my car is worth less than a pair of new Nike Jordan's at this point. Sucks, especially when you have NY winters.

I guess it is called: Buy a car that is worth more than $10,000 and you won't have that problem.

i had to register to this site when i saw this, anyways here goes my first post. I had this same exact problem with my girlfriends 99 accent and the problem was charcoal clogging up the vapor tubes going into the charcoal canister. Its a pretty easy fix all you need are a 10mm socket and a pair of pliers. On the car i worked on the canister is on drivers side rear corner. Just take the tubes off there should be two of them a fat and a skinny tube. Just blow all the charcoal crap out of there and you are done. It kept happening to me so i had to get a new charcoal canister. I was lucky and found one at a junkyard. I'm afraid to know how much a new one at the dealer is. Your car should still be under warranty so they will change it free of charge.
Hope this helps,
Chris

I have the same problem with my 2001. I have talked with the parts dept at the dealer and the canaster is about 180 bucks. Just putting off replacing. I'm going to go to the junk yard first.

ive seen this problem before ive been in the car business for 12 years and it happens when the fuel vapor system fills up with fuel ive seen this happen to all makes of cars over the years i have worked under 10 different auto makes and it is more recent that this problem has started. emissions laws require the manufacturer to recapture the vapor from the fuel tank instead of releasing it into the atmosphere. it is very common with people who we called (clickers) they keep clicking the gas pump until it wont pump anymore gas in the tank the problem is if this is done it fills up the fuel vapor system with fuel then its like trying to pour gas out of a gas can with out opening the vent you can do it but the air in the tank has to fight against fluid to escape.its the same idea with pumping fuel into the tank the air has to beable to escape somehow. you may have to replace the fuel vapor purge solenoid (sometimes called a canister close valve) and canister to get this fixed a used one might be plugged up too .i hope this info helps

Moodude, how does that apply to those of us who do not overfill the gas tank and who have the problem as soon as the gas is pumped? I have a 2005 Accent that is new to me and previously was a rental. Thanks.

If the vehicle was topped off, the vent lines can be plugged. If it is a 2005 and has less than 60,000 miles (and you are in the U.S.), the car is still under warranty. Take it to the dealer and see if they will help you. I had some problems with that system early on when I bought my car new. They never fessed up, but I think the dealer over-filled the tank when they delivered the car. Driveability was never an issue, but I kept getting a Check Engine Light. It took a few visits to the dealer but eventually they fixed it under warranty.

Because of the car's history (rental), a dealer may try to say this is not a warranty repair, and that may even be correct. But try to sweet-talk them a little. I've never had a problem with local dealers, but I try to make a point of being congenial and not confrontational.

I'm having the same problem. The gas pumps for about 3 seconds before it shuts off. Takes about 10 minutes to fill the tank. I see that people have fixed it by removing charcol from the vent tubes. Can anyone tell me where I can find the vent tubes and charcol canister in order to try to fix this?

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?

Charcoal canister was leaking pellets
 

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

Still
 

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.

Gas filling
 

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

It will trigger a C/E light because the evap system cannot work properly. Knowing how temporary fixes go, best to do the job right.
