Does the gas pump keep stopping over and over while you're trying to fill up? You know it's not full, so what else could it be? In this video, Andy diagnoses this very problem, and explains how the charcoal filter canister that is part of your car or truck's EVAP system could actually be responsible. Since the fuel tank is a sealed container, when you add more gas, air is pushed out. If the air has nowhere to go, the increase in pressure triggers the safety stop on the fuel pump! Watch this video to see Andy demonstrate how a blocked charcoal canister can cause this problem!

WHAT IS THE PART CALLED??
I’ve replaced the valve, and the canister. It’s still not filling properly. Please advise.
When ever I gas my van up, the fuel starts coming out of a pipe attached to the main fuel pipe that right under the body and tank. It branches out and I guess its a run off valve so when you've put too much fuel it comes out there. I guess. What's the problem?
Also I've needed to replace my blower motor on my van, but I'm not getting the new part in bc it's a very tight squeeze bc if the black metal tube that starts in the side and runs over the battery. I hit the old part out bc I bent the housing fire the old blower but obviously I can't do that to the new part. Any tips?
It's a 2004 Ford Econoline Van 150 5.3L V 8. Just to let you know just in case.
Gas prices have prevented me from filling up my tank.
Don’t drive a big old V-8 then🤷🏼♂️
@@daveerrington5166 i drive a v6... and this also effects me, i got friends that drive 4cyl economy cars that cant afford to fill an 11 gallon tank
Think I burnt my fuel pump cause gas to much to fill up
😂😂🤣😀💯✌🏽.
REAL" TALK 💯✌🏽
Let’s go Brandon!!!
I can just imagine crawling under my 05 mustang to replace this canister 🤣. It won’t fill easily but I’ll live with it. It’s just a slow process.
My 2005 Ford Mustang has always kicked out the pump and I have had to trickle gas into it, since I bought it when it was only 4 years old with 36,000 original miles.
this is happening to my 2019 mustang, it stops so many times but it fixes after I take the hose out and put it in again
Roommate had a car with this problem and we just lived with it ... It's a pricey repair from what I understand. So annoying though.
I have a 22’ Ram 1500 limited Longhorn with the 33 Gal tank. Now with about 50 miles left for range, I only get about 28 gals in the tank. I know at 50 miles left there can’t be 5 gals in the tank remaining. Is this normal?

Navy mechanic here. It's rare for it to actually be the charcoal cannister, usually it's the vent line needing blowing out. But when it is actually the charcoal cannister as the problem...it's because you keep clicking the gas at the end trying to get every drop you can in the vehicle! That causes fuel to reach the vent line and trickle back into the charcoal cannister and stop it up over time. When you're fueling up, stop continuously clicking the fuel trying to get every drop possible! Maybe do it a couple times and stop, and you'll never have charcoal cannister problems.
Wonder how many could read this comment. Thanks
Crayon eating Marine here: What if outside temp is a factor. Cold days nogo
Warm days all good
Words to live by.
@@ghostmost2614 living in northern canada this is my problem also! If I thaw out in the shop overnight I can fill again the next day.
THIS IS MY TRUCK!! I bought this off you guys and it still has a check engine light on for my evap system
May I ask how much the average cost is for this kind of repair at a auto shop? Thank you for the very well detailed video.
God I love you guys! Thanks so much Andy, I have a small (MOM & POP) car lot and have to do 99% of repairs myself as well as be the salesman. Your videos has helped / saved me so many times as well as saved time and money. I have become a 1A auto customer, most my local parts store no longer deliver nor do they seem to carry many parts. they tell me they can order parts needed, so I came to realize that I can order parts ( FROM 1A AUTO ) )as easy as they can for a much cheaper price from 1A. THANK YOU AGAIN AND I REALY APPERICATE THE HOW TO VIDEOS
Watched this video and one thing not mentioned is that this is and remains a common issue for Chevy trucks which is what he's working on. Another design flaw by Chevy was and is the short run of the filler tube and the bend in it. I've seen brand new Chevy trucks do this and obviously there was no blockage in the canister.
2017 chevy Colorado ZR2 owner here. I have the same problem! More GM junk. My last Chevy for sure.
My 2005 Ford Mustang has always kicked out the pump and I have had to trickle gas into it, since I bought it when it was only 4 years old with 36,000 original miles.
I have a Chevy Suburban 2013 1500 LT and I'm facing the same issue. Changed both the canister (OEM Part# 22963841) and the canister vent (OEM Part# 23481275) and still the issue is not resolved. I filled 80 liters yesterday in 27 min 😥.
Any idea what else can be done to fix the issue
Lmk please
What if it only happens at a certain gas station?
Good question. Had it happen once last year and now today at same station. Hate to spend money on service if this is just random. Wonder if desert heat is playing a part.
That's why I'm here, did you ever figure it out, besides just avoiding that station?
I found that my truck only takes gas at certain gas stations, i feel like some gas pumps have to much pressure an some pump smoother
I had this issue with my 2017 Silverado recently. Thanks for the informative video.
Im having issues as well while fueling but mine is spilling out the vent solenoid and it recently started to over flow out the filler tube. I replaced the vent solenoid, charcoal canister, blew out the lines but I'm still having fueling issues. When I replaced the canister it fueled normal for about three fill ups and then started having issues again. I noticed fuel was going into the charcoal canister and also sending it to the purge valve which I also replaced on the engine side which was causing it to run rough and throw a P0300 code. I cleaned out the canister removed al the fuel inside and blew out the lines andit did help it for about a day with the running rough issue but it seems like it starting to push fuel again to the purge valve and causing it to run rough again. This is on a 2007 Silverado 1500 classic. Any suggestion on what I should do next or what it could be?
have a 07 yukon denali with the same problem ive replaced every part even cleared some lines and still can barely pump a gallon of gas before filler neck fills up and wont let me pump gas
@@gabanna9735 did you ever find a fix? My 07 is doing the same thing. I replaced purge solenoid canister and vent valve. And when getting gas it keeps popping every few gallons. Takes forever to get gas.
If you are saying that the pump keeps popping which prevents you from pumping gas in your vehicle. You might want to do a babysitter fill. It when you keep the pumps nose slightly lifted while pumping. This isn't actually a fix, but it does allow you to put fuel in your tank. Becareful not to over fill and it is even better if you know how many gallons your tank is. Good luck!
@@fierceeagle2003 did you ever figure out
Only problem is my vehicle is practically new
My ram keeps stopping at the pumps too when I fill it up every 5-7$ just stops an bugs me.
good stuff, you guys. I'm having this issue with my '14 Silverado as well. but a friendly question to narrow down my issue. when I turn my truck on, it doesn't crank immediately as it maybe should. and when I turn it off, it shakes a little time to time. could these things be because of a fuel blockage? I have changed my fuel pump, but these issues were before even that. I purchased it recently at a used car dealership. I've used the scanner and do have a code for a fuel/oxygen sensor. 🆘
Could be your evap purge valve. Usually under the hood on back top of engines. Not sure if its Left or right side.
Great video and very detailed. Appreciate the time and effort in this. Q: Is the design concept the same in every vehicle? I have an 07 Mercedes’ S550 and this issue is annoying as f*•! when trying to pump gas every time lol excuse the language. Your wisdom is greatly appreciated.
EVAP system is the worst thing ever! Especially on chevy! The whole thing keeps giving me nightmares!
Excellent detailed show and tell! Thank you. Will be using it as a guide for my truck's gas filling issue.
Seems easy enough to take a look at myself but I was wondering if this would be something I could do at home (without any kind of lifting of my truck)?
Warm days fills fine
Cold days blockage
???
Question, before I remove that charcoal filter do I need to take all of the gas out of the tank? And if so how do I go about doing this?
Very well presented video of a common problem in a wide range of vehicles. I also have that problem with an Avalanche and a Hummer H2 including the check engine (MIL) light and a P4520 error code (Evap Code).
I have this issue on a 2012 Chevy Silverado LT 1500 Z71. ok that being said...I replaced the EVAP canister, Purge Solenoid, and Purge Valve and still have this issue. HELP!
cant you just connect the hose from the gas tank straight to the hose going to the engine? That will allow the engine to still burn the fuel vapors without all the unnecessary charcoal canisters and solenoids.
That sounds logical, but I often wonder if all these systems don’t cause our vehicles to get worse fuel economy.
This was a very good video!
I have a 2005 Silverado 2500 hd 6.0 I've removed the canister and the vapor line from the tank to the canister and it still won't accept the gas. then with all that disconnected I blew air into the tank at the fill up end and it blew the air back out at me then I tried the vent neck and had the same affect. i used my camera and nothing is stuck in the filler neck.
How much would this cost for someone like me that has never been under the hood?
What in the fk causes this anmoying !$& problem??
Should the breather tube have gas in it?
When I search for charcoal/EVAP canister /filter I’m getting no hits to price or order said part. What words do I use to find the part for my dodge ram?
We change the charcoal canister and the solenoid. Gas still will not pump without clicking off any other ideas what it could possibly be?
Im having the same problem on my 2018 ram 1500
My car that problem lol
I'm no mechanic
But I'll try it in the spring 2022
Watch your teeth...... 😁
Thanks for the video. My sons truck is having the same issue. Btw. You look like John Malkovich.
Thanks for the video. I have this problem with my 05 murano
Thanks for the video. Good to know for future reference
Help: I've had my fuel tank changed for a brand new aftermarket one because it was 1/4 the price of OEM. The top side valve on the tank is 3mm wide, the OEM one was 10mm. I've had to buy a brass reducer and some new pipes to bridge the gap between the new valve and what I assume is the charcoal box you mentioned (although the mechanic did the work so this is a guess). Now when I fill up the fuel pump clicks and stops every few seconds. Could it be because of the smaller valve on the tank?
Can you offer any advice on what I can ask my mechanic to check or what might need replacing?
Is that vapour valve something that would cause the fuel not to fill up correctly?
Car is a Toyota Celica 2003
Thanks
P.s. good video and well explained although it's not exactly what I was looking for
this happened to my avalanche a few years ago. When I couldnt put any gas in it, the first thing i did was take the hose loose at the purge solenoid at the intake and it was full of little charcoal pellets, so i knew exactly what the problem was. I fixed my a little different than you did. I took my old charcoal canister out, cut an access hole with my dremel, emptied the canister, taped it up with flex tape, and put it back on. Now i can go fill up as fast as NASCAR.
Before you did any of that, did your avalanche run rough ?
cant you just connect the hose from the gas tank straight to the hose going to the engine? That will allow the engine to still burn the fuel vapors without all the unnecessary charcoal canisters and solenoids.
Good day Timmy Timmy So did that work. Pellets were do u buy them from Thanks
Will you pass an inspection?
@@graciegjj where in the world is your vehicle being inspected..??
If I accidentally leave the car running while I’m pumping gas, will vapors, or gas enter where it’s not supposed to go (please excuse my lack of Terminology for the components of a car)… would that activate the check engine light on?
What a palaver. All we used to have was a tank and pipe going to the carburettor with a inline filter.
There must be more Polution making all this junk than the polution it saves
Thank you for sharing by the way thats a lot of rust under that truck
What about gas spewing out at the end of the fill up? Pump does not automatically shut off on its own.
I’m having this problem now. Just had the charcoal canister fix- $335 and still having trouble getting gas in!!!!!
+@sylviamcdade9098 We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
What about diesels ????
what about for f250 2000 diessel thanks
I’m about to look under mine now
Thank you so much for this excellent video.i have the same issue happening so I filled up gas container and then i poured the gas into the car.
Might this affect a diesel. My friend has a vauxhall meriva diesel that has the aame problem
Nice video. This was by far the clearest explanation of the evap system that I've come across. Thank you.
Hi, thanks for the video.
Does it make any difference with drive or consuming more fuel?
Wow look at all of that rest rust under the truck.
Having this issue on my Chevy avalanche 2005 super annoying
what about ford f250 2000 7.3 diesel help please
Ever found the cause ? I have a 1996 f250
This still happens, even after I bought a new vent valve, purge solenoid and vapor canister and fuel cap. I also blew out all evap hoses with compressed air.
I STILL can't put gas in the tank. 2002 suburban. PLEASE HELP!
Love the video!!! Perfect presentation and made swapping my 2005 Sierra parts as easy as it gets. Keep up the great work.
I have a 2010 Ford Fusion. I need to use the slowest setting when filling up. It takes 12 minutes to fill. This car is garbage. It's full of rust and corrosion. Typical Ford product. I can't afford to buy a new car or the repairs.

Everytime I fill up my turk what to die on me
No what you did shouldn't take in Care of the problem
Definitely have to give some of these a try. I have a problem with my 06 Liberty
First thing I will need is a lift in my driveway. Shouldn't cost more than five thousand dollars delivered and installed. Maybe six or seven thousand.
The activated carbon in the canister is sized to the fuel tank. The Marine is correct that pumping the last drop can cause the filter media inside the canister to tear as it’s under spring pressure. This leads to black carbon chunks in the purge line up to the valve & engine.
The A1 Auto tech diagnosed the symptom but not the root cause. The fuel tank solenoid is open all of the time until the PCM runs an EVAP test after 4-6 hours of drive time at temp. Since it’s open, allowing air in, it has a foam filter in it or separate like this one. East to open with pocket screwdriver and dump a pound of dust out. This plugs canister way more often than anything. If the tank solenoid can’t close durning an EVAP test, a code for small or large leak will set. A loose gas cap is common. The filter could be cleaned, but replace it if you can afford it. Two wires, one or two hose and if you see thru it, spray WD-40 and quickly blow compressed air thru it. Installing rubber hoses is easy if WD-40 is sprayed, all hoses. That’s all I use it for! Ever. OBD-2 codes are in 4 categories but concern yourself with “B”. Codes in “A” turn light on now, type “B” detected problem like small leak, if refueling and 2 gallons or more added, time to run test, it shows “Check Gas Cap” this is how & type “B”. If Crooked or loose, drive, park, coolant & air temp within 10F of each, drive to temp, runs test, passes! Now repeat 40 more warm-up cycles, type “B” code disappears, congrats! OBD-2 is complex computer software and once engine is started, it takes 3-6 minutes to check everything. Complete understanding is hard but I learned it in shop, then taught it for almost 7 years in 7 or 8 states for up to 100+ techs!
Best of luck! ASE Master 78 + L1
i have a 1985 that does this do you think it could be that
Im having this issue with my box truck… it’s so frustrating. Takes me 40 minutes to fill up my tank
I get that problem at Costco gas pumps only
Having error code P0441. When taking off the gas cap to fill tank there is pressure it vents. Also when filling it kicks off the pump frequently. This is probably my problem as well?
Thank you so much for this information, it is definitely some useful information when diagnosing.
What about diesel
So i change the evap silinoid ,charco canister ,purge valve and still clicking at the gas pump .pls help me out im so stressed over this issue ....i spent alot of money getting parts and a mechanic and nothing what should i do next ..i basacily change the whole evap sistem and still clicking!!!!!😢😢😢😢😢😢😢😢😢
Why not run the vent hose to the front and add a filter?
i've replaced all those items and still can only fill up 2 gallons at a time, really sucks when it's cold out. and with the pump shutting off constantly you have no idea that it's full.
Did you ever get it repaired?
Same, did you find the problem
I had a half tank gas when I decided to top off prior to entering the Gettysburg battle field for a tour. I only Got about a dollars gas in when the nozzle started shutting off and spilling out gas. I couldn’t get any more gas in. (2019 Jeep Cherokee). Called a Jeep dealership and they recommended bring in the car. Decided Toft to our destination and see what goes. Tank should 3 quarters empty when I pulled into a gas station. Holding my breath, I had no problem topping off the tank. Car ran fine rest of trip. Gonna try again when at half a tank just to see what happens before i take to the shop. 🤞🤞🤞
Alright, I have deleted the charcoal canister (temporarily as a diagnostic), I have installed two completely new vents on the top of the tank (they should move way more air than the OEM vent line), I have replaced the solenoid and also the purge valve. It still won't fill at the station without either clicking off or pouring out the top of the spout. If I fill it slow, I can fill the tank, it just takes a really long time. 2008 Chevy Uplander 3.3
I remember someone in a Ford Explorer was doing this. I thought he was crazy.
Hi how are ..iam s good fan of you lam from iraq..i like your videos .. they're really beneficial..i need your help if you could dhow me how to fix ssme problom of canister and vapor in malibu LT 2019..
Thanks from
Actually it's very common for Chevrolet truck..... charcoal canister brakes inside filling the vent hose with charcoal
I did this same job on our 2002 Suburban. It solved the same issue for about 6 months. Now I can't fill it up with gas again.
New : purge solenoid, vent valve, charcoal canister, and gas tank cap.
Any suggestions?
Very well detailed video thanks for your high quality tutorials I’m constantly learning with you guys
Great informative video,sir. I have a good 2003 Dakota , 4.7 4wd,lottsa miles...Gas pump keeps shutting off and i need to sneak in the fuel gently. I have po440 and po443...Got a new purge valve on a whim and then it threw the 443...Need to get it inspected.......Charcoal canister bad ? LDVP stuck? New gas cap didn't help.....Pllease assist if you will.. Best of regards, Rob in Albany,NY...cheers
I'm having this problem with my 1997 F 250 with duel tanks , didn't have this problem till after a shop replaced the fuel pump. Note: I only use the front tank.
Have a 05 Volvo S60 2.5t my check engine light came on PO456 small EVAP leak. Had a smoke test done found out it was the fuel filler neck vent pipe small leak. This part is discontinued.garage called around and could not find another in my area. So the mechanic said he could try epoxy. Took my car to get gas and the pressure coming out of the fuel filler neck was strong. Could put too much gas in my car. Pump kept shutting off. Taking it back to the garage to see what they can do. It could be the charcoal canister or the line needs to be blown out or when putting the lines back on they are kinked. Possible human error. Will have to see. Very frustrating
I have 2006 Cadillac Escalade I smell gas around the end from my truck do u know what’s the problem can u help me out thanks. I was think I’d the evp valve I was try to do the easy job first.

Hey we have a 2013 Dodge Grand Caravan rt, every time we go to the gas station and start fuelling it stop at $10 and then stop every $0.10 or $0:40 cents. It’s been driving me crazy, we spent a lot of money in it and still couldn’t find the problem. Please help or tell us the best place to go fix it in Springfield IL, thank you so much, please help out.
Hi Sr need help with my Chevrolet Sonic 2014 1.8 brakes front warm. And need to stop.no code or ABS warning. Thenks. Do you know about like this before. Thanks.
I installed a new charcoal cannister and my problem still exists, even installed a new fuel filler neck with it's own small canister....I can't figure out what the issue is on my 2018 Ram 1500
I had this problem on a 2003 Chevy Impala. When I turned the engine off when filling the tank the pump kept shutting off. I then turned the engine on to fill the tank, and the problem was gone. It was the vent solonoid. When the engine was off the solonoid was stuck closed so the fumes in the tank were unable to travel to the canister. When you fill the tank you create vapor. When the engine is on, the solonoid opened and the fumes were able to travel to the canister.
I am having this issue with a 2020 Longhorn I just got. Do you think this is something the dealership should fix? Or is this something I should?
Got this issue with my 2011 ranger its annoying trying to fill it up. Maybe this is what's going on, I don't know
Having this problem with my 07 Chevy Trailblazer. Is this the same process to fix or try to fix my car???
Liked the video. Have a 2006 suburban. Its spraying gas out of the filler tube, while filling. As far as i know its not hard to fill, shutting off the pump. Would it likely be the same thing that you cover in the video, the charcol canister?
Is this the problem that’s happening with my Ram 2020 Rebel ? They said I needed a new filler neck and replaced it but the same problem is happening .
Hi mate ,
I have ford single cad ute with aluminium tray. I just bought it in march. But this is the problem when i go to petrol station to fill the diesel , same problem happens evrty time. What shud i do
Replaced my charcoal canister and it didnt fix my problem.. im assuming the vent hose is clogged
I don't know if that's the problem but you gave me a few ideas I'm having a similar problem on my 5 series BMW
Let me know if this is correct:
At 8:11 you used an air hose to pressurize the evap charcoal canister. It was plugged and the pressure remained in the evap charcoal canister. I am guessing that the fuel gasses from the tank will get stuck in the charcoal canister and the air pressure will exit out the normally open vent. You are right, a balloon on the outlet vent would have been a great idea.
So assuming from the last three videos of yours I viewed on this subject, (car sitting and not running) I am fairly sure that the fuel vapor from the tank exits into the charcoal canister, the fuel vapors get trapped in the charcoal canister while pure fresh clean air (no gas smell) from the pressure in the tank makes it through the charcoal canister (valve open) and exits the tank through the vent valve, causing no pressure to build up in the tank. The fuel vapors are left behind in the charcoal canister.
On the other hand, when the engine is running, the purge valve opens, the vent valve closes, and the resulting low pressure in the charcoal canister releases the fuel gasses trapped in the charcoal into the engine intake manifold. --Zero net loss of gas vapor related to evaporation. No stinky gas smell from cars when wandering through a parking lot.
When you overfill the tank raw gas gets into the charcoal canister and ruins it. This would be the stinky car.
