Gas Tank Won’t Fill? Cant Pump Gas without Clicking? Free Fix Charcoal EVAP solenoid purge valve DIY 

is the vent line and vent valve on the part that he was messing with?

@@jjgarcia6833 it does not appear to be but it’s hard to tell. On that vehicle the vent valve may be mounted separate from the charcoal canister. The vent valve will have a vent line going to it and also an electrical connector.

Heads up man. I got a 04 chevy express van. Same issue. It was a bear pulling that canister off and it not fix my issue. There’s also a small purge sensor that regulates the air flow right next to the canister. It’s like 4” tall lil can th at goes bad and stops the flow. U can just unplug it and try to fill the tank first. If that works it’s not the big canister. I’m gonna try that next.

Any issues after doing it?

Did you notice poor fuel economy before flushing?

Could you elaborate on this a bit further? You pulled off the charcoal canister, flushed it with a old fashioned house (water) and then dried it out with a tire pump? How's it working now after 5 years?🤣

​@@kyleg3725He said he used a tire pump. He must have pushed air through it in the direction of the tank. Good idea actually.

Glad it helped! Still going strong 💪

@@BobHGarage That's awesome!

​@BobHGarage any updates brotha?

Which is due to the mesh deterioration within the canister, as told to me by the mechanic. He said if we would put the line back on that it would just plug up again. I can’t verify that, but so far leaving the line off, after blowing out all of the debris, has worked wonders.

Agreed, if you’re in an emissions testing state this is probably not the move for you if they test your gas tank emissions. Otherwise you’ll be good to go, all the charcoal canister does is reduce the gas vapor smell before routing the vented vapor to the intake manifold vs letting it vent to atmosphere. This will have zero effect on tail pipe emissions 👍

So mine is stopping to I want to get this fixed what was the problem and how much you were charged?

Or you can just pay for inspection sticker...😂😂😂

Well they probably shouldn’t look underneath mine…removed catalytic converters too. Yea, if China can burn coal like crazy…I am not the problem.

Done with emissions and all the ridiculous crap we have to put up with.

I own a brown leather jacket which is 99% because of his influence

Good to go no issues. It’s all there for government emissions nonsense. You don’t need it

It will not pass state inspections and if the state policeman especially here in Texas catches you it’s a $10,000 fine just replace it it’s not worth going through the heartache later when your truck is not running properly and then at the mechanic finds what you did he can report it’s his obligation To report any Pollution control devices modified . Do not take advice from people that are not technicians. ✝️✝️✝️

@@loveofchrist5808 You’re honestly a joke. How bout you pay for everyone’s repair then.

@@loveofchrist5808 I see your point of view but everyone is already getting fisted by Uncle Sam you really think they will go through all the extra effort to report you rather then maybe upcharge?

Lol mechanics ain’t snitches. They’ll charge more only

🤦‍♂️ of course they did.

If it’s the purge solenoid that failed, it could damage your gas tank.

Where the h2 2007 canister located? Thank you

Dealership service departments would rather climb a telephone pole and tell you a lie than to stand on the ground and tell you the truth.

Forgot to mention this was an 07 durango. If the charcoal had been clumpy I had planned to heat it in a pan over outdoor stove to dry it and reuse it. Why spend money to replace when it's more fun to try to fix it yourself. Always learn something whether it works or not

Nope. Found a better solution on my wife’s truck though. If you have access to HPTuners you can just remove the vent line that goes to the charcoal canister. Then when it throws a code for an emissions leak, just delete the CEL code from the ecu.

If you disconnect the big vent line going before going to canister it should fill up with no problem it would seem ( nothing but vent hose coming from tank) but still want take gas. i only have 4 gallons in it though? (Basically tank, filler hose and push in pressure switch) all lines off pump except fuel line???

In front of the spare. Super easy to get to

@@BobHGarage I’m gonna look, because the canister did nothing.

Give it a shot, you can always plug it back in. But you may end up with a CEL. No reason not to try

Did that work? I cleaned out my canister and I still have the not flowing problem.

@@rolandvillarreal2687 Pulled off the hose, NO did not work. Then blew an amazing amount of charcoal out of the line. Continue to blow the charcoal out until you hear air rushing back at you with the odor of fuel. Then I left the hose hanging. Took five gallons without clicking off once. Would of put more fuel in it, but that would call for a bank loan.

@@BobHGarage I did this fix today. I went to the shell and went to pump gas and the first time It did click but the second time it seemed like something let loose and I pumped 8 gallons without stopping.I was also hearing something underneath like the pellets going through a line or something. So far so good.Thanks.

If the filter that contains the charcoal fails (& they basically disintegrate over time) it allows the charcoal into the evap lines causing an obstruction there so it's a good idea to blow out the lines w air.

The better fix is to just clip the lines leading into the charcoal cannister and let the gas tank vent to atmosphere. Unfortunately though you will need HpTuners in order to remove the check engine light if you go this route.

@@BobHGarage I don’t necessarily care about the CEL. My friend is concerned that the evap is a saftey issue not environmental one. Keeping the vapors in the system. One cigarette lit next to my car will cause a potential explosion he said. Thoughts?

Up under near the spare tire

Every 100k miles

You ever figure it out? I did this and replaced the evap solenoid and still have the issue

No.

Thanks, I changed the charcoal canister, purge valve solenoid and charcoal canister solenoid valve. Same issue

@@robertsestate6421same with me. I am guessing one of the lines are still clogged up. I just haven’t had time to take it all apart again and blow everything out. Again.

$130

No codes this way. Better way is to just clip the vent lines to the tank and eliminate this whole charcoal system all together… but then you will get codes. But $200 for HPTuners and you won’t have codes

If you do that you will get a check engine light. But yes, the better way to do this is to just clip the line and vent to atmosphere. But then you will need to purchase HP Tuners in order to delete the check engine light. So about $300. What’s in the video is how to do it for free. 👍

@@BobHGarage I’ve already got emissions tuned out of the computer. I won’t get a check engine light. It’s just that when I had the vehicle tuned I wasn’t having this problem.

Just clip the lines and let the tank vent to atmosphere.

Which lines?

@@martinchacon6666 the lines from the gas tank to the charcoal canister. Clip them closer to the canister. You’ll get a check engine light which you can erase with hptuners but you’ll never have the filling problem again.

Thanks a lot brother was very helpful. Never thought of that 🙏🏻

A few months later and I still haven’t gotten one. If you’re gonna keep the truck for a while it makes sense to spend the $200 for HPTuners, even if you’re not going to do any tuning you can turn off check engine lights

Thank you sir

Correct. But it doesn’t happen often.

Is this dangerous??

@@kyleg3725 It's most dangerous point would be during refueling as you're causing a big surge of air volume (empty tank) to be displaced by fluid (gas), sending all the fuel vapor out the breather tube. It's about as dangerous as filling an ordinary gas can.

@@cup_and_cone but on a bigger scale, but thank you!! That puts it into perspective for me!

Check your purge valve and blow your lines, maybe your solenoid too

There’s a vent valve up on the engine next to the fuel rail. Try that

@@BobHGarage the line to the charcoal canister (the center one on the fuel pump) was clogged on my 05 tahoe and that middle line is what lets the air out of the tank, into the charcoal canister. You have to get an air compressor and blow out that dirty line while it’s disconnected from BOTH sides, and then your problems are fixed!! My vent solenoid was already bad and it fixrd a code replacing it, but these fixes, even blowin out the charcoal canister itself did nothing to help the fuel filling issue. Only cleaning that middle air/pressure line will help with the fuel delivery. Hope this helps!! Nobody ever posted about this on YT or anything so i hope you get a video out about it. It would help a lot of people who already tried to fix the problem like me. Luckily i don’t have an exhaust still so i can always go back in and fix it. Soon.

@@BobHGarage figured i’d say that since you still reply to comments. It would be a great fix for you to come out with.

your purge lines are prob clogged with charcoal pellets, disconnect purge line from canister and check for pellets

my h2 has been doing this for months but i just now got a p0455 evap leak, any suggestions?

Don’t replace the tank. Just clip the lines from the tank to the charcoal canister. It will completely solve the problem. The downside is you’ll need to spend $250 on HPTuners to go in and remove the check engine light. But absolutely do not replace the gas tanks. That’s insane and the shops are trying to take advantage of your lack of knowledge.

@@BobHGarage I figured there was a way to bypass the damn issue. They wanted $2400 and I just laughed. Wonder if there is a video on that? Would the light continuously come on once done, or just once?

@@Optimization_Coach yes it’s an easy solution. I did it to my wife’s Escalade years ago. Just never made a video and we don’t own those trucks anymore. But you will get a CEL that will stay on. If you reset it, it will always come back. You’ll need HPTuners to completely delete the code from the computer.

U did it wrong 😑

Last resort, but HPTuners for $200 and then disconnect the tank vent line to the cannister. Leave it disconnected. After a day or so you’ll get a CEL for an evap system leak. Open HPTuners and select that CEL code and turn it off permanently. You’ll never have a problem again

I can absolutely guarantee you 100% that there are no charcoal pellets in the evap lines.

@@BobHGarage that's good for you and as I said you got lucky.

The truck caught fire and burned to the ground two years ago…

Did it burn down because you took all charcoal out or something else happened and is ok to run it without the charcoal in the canister? Thanks

@@BobHGarage Is this legitimate? Or are you trolling? I am looking to fix mine and hoping this solution did not cause your car to burn 😬😭

Definitely an intermittent problem. You’ll either need to fix it how I showed here or you can just cut the vent line off the tank but you’ll need HPTuners in order to delete the CEL. I can make a video for this as well if you guys would like.

yes please@@BobHGarage

Next to the gas tank

Right above the rear end

So you don’t have a bunch of lines dangling around lol

Crawl under your Tahoe/etc, driver side, look for the gas tank, then look for a car battery size black box with hoses connecting it to the gas tank.

Did you know that charcoal is just burnt wood?

@@BobHGarage yes, but not after used as a filter for fuel.

Haha. So, that is your take-away from this video?

PETAs in da houusseee 😆

@@BobHGarageman drive a gas guzzling suv but worried about the planet 😂

Lol warranty on a 15 year old truck!? 😂
