I think the charcoal cansiter needs to be replace on my 2003 sonota. I have a diffcult time pumping gas onto it it the gas nozzle clicks off as if the tank is full. Can it get it from a part store, How much does the part cost and how much will it be to replace it. Also will it require me to take it to a repair shop?
If your ck engine light isn't throwing a e-vap code don't mess with your canister unless you pull the vac line off an gas poors out of it.Reposition your nozzle an pump slower this is common with many cars.Save your money.

The vent valve is stuck closed or you have a pinched hose . It has to do with the Evaporative emission's system ! There is a charcoal canister under the vehicle that stores gas fumes and a vent valve that allows the air in the tank to escape while fueling the vehicle, an during use fuel expands an the fuel vapors get stored in the charcoal canister an at times the engine control module turns on a purge solenoid that is connected to a engine vacuum supply allowing the fuel vapors to drawn into the engine to be burned !

If its running o.k. Than I would bet the check engine light is on because there are codes for system too lean.
Burn off the tank of e-85 as soon as you can, than fill with regular unleaded. The light should go out after several drive cycles after everything has gone back to normal or you can swing by ou local parts store and see if they can clear the codes
Sally, the problem is the charcoal vent system. A new one will cost about $150.00 but......... the total fix will require the cleaning of the vent valve on the gas tank. You will find small pieces of the charcoal (pellet size) in the valve. You must look close to see them. Think pencil lead size. Remove them and exercise the valve some. The valve is a push in and out type. I don't understand the reason the charcoal pellets make their way to the vent valve at the tank but they do because I found them in mine. They must travel out of the canister and up and over a dry loop in the vent line to get to the vent valve at the gas tank. This would take some vacuum to cause the pellets to travel. It also requires the poor construction of the factory instaledl canister vent outlet because there is a filter at the canister that is supposed to contain the pellets. This will verify you have gotten all the charcoal pellets out. The charcoal canister (located up under the fender is easy to replace). You can make a cheep fix by installing some scaring pad material in the vent connection line at the canister but that doesn't address the charcoal being plugged. This will keep the charcoal pellets in the canister. You will have to drop the gas tank partially to remove and clean the vent valve. Keep in mind you are working on a gas system that is very dangerous. i.e. it doesn't like spark's. Only begin this job with a tank that is all but empty. You can find diagrams of the vent system on the internet. So you can identify the parts I have referred to here. I have done this work. It is not easy. It is an under the car and also through the car trunk operation. You will have to remove the gas pump via the trunk from the gas tank. Remember about the spark issue when you do this part of the job. This problem is very common with Hyundai's and several other cars. It is because the manufacture has reduced the gas fill piping to roughly a 3/4" pipe and installed a government requied venting system that you have this problem. You will see that at the tank the opening is as fill lines used to be about 2" and at the gas nozzle area also about 2'" but the rest of the line is no larger in diameter than the gas pump nozzle. That is not to place the blame all on the car manufacture. You see it is always the government that is behind our frustrations in life. The EPA has told the car companies that the gas vapors we used to smell when the car was being fueled are no longer aloud. So the need for the charcoal vent system to capture the vapors of the gas as fueling is being done. Some car people have said that if you never overfill your tank these fueling problems never happen. i.e. the charcoal in the canister never gets wet with liquid gas only vapors. Note the warning stickers and owners manual cautions to stop the filling process when the gas nozzle clicks off the first time. Sally you will know if you have not followed this advise and fueled your car clicking the nozzle several times after the first nozzle stop. That is the way we used to fuel the cars in the good old days. However, I do almost all of the gassing of my car and I had the problem. So I say the car manufacture is responsible for the issue with poor designs in the system. Lastly I can't stress enough the importance of not doing this job as a back yard mechanic operation because of the volatility of the gas. It can and will blow up if not handled correctly. Good luck!!!!
SOUND LIKE EVAP CONTROL SYSTEM NOT WORKING.COULD HAVE STOPPED UP FUEL SOAK EVAP CHARCOAL CANISTER.OR THE PURGE SOLENOID NOT WORKING ALSO GAS CAP COULD BE FAULTY.HAVE THE EVAP SYSTEM CODE SCANNED.WHEN PUMPING GAS EASE THE GAS SPOUT OUT JUST A LITTLE SO YOU CAN PUMP GAS IN TAKE.REASON CAR WONT ACCEPT GAS BECAUSE EXCESS GAS VAPORS CAUSES PRESSURE TO BUILD UP IN FUEL TANK IN WHICH WILL KEEP GAS FROM BEING PUMPED IN FUEL TANK.
Hello! Do you have a Check Engine Light on? The charcoal vapor canister filter needs to be replaced...If the filter inside breaks charcoal particles will end up in the gas tank and foul the fuel pump...The filter cost under $10 the canister is $100
After change fuel pumps per diagnostics still had problem with starting after fueling. Researched on-line and kept seeing purge control valve as solution. Mechanic didn't think it would do anything but filled up three times now and so far so good. part was $49 and he was nice enough not to charge for labor
I would replace your fuel filter. It is cheap and should be easy to
replace if I was going to guess. A clogged fuel filter will cause poor
fuel flow and can cause stalling. If that doesn't help I would get to a
repair shop because cars are difficult to diagnose without a computer
