What's up Jeep fam! Today I talk about a major issue for those of us who love our jeep TJs! This is the issue of the rollover valve aka the fuel tank vent valve. The purpose of this valve is to prevent fuel from spilling when the jeep rolls over. It is also connected to the vehicles emission system through the evap lines. If the system detects a leak in the system, it will throw engine codes such as p0456, p0455, p0454, etc, depending the size of the leak. Now the issue lies right here - that the original rollover valves are now becoming old and brittle on the tjs, and with one wrong bump or sudden jolt, the elbow can break thus leading to an evap leak. This is unfortunate for 2 reasons, 1 because now it will not pass emissions testing, and 2 because these valves are not replaceable, you must replace the entire gas tank, but they don't make replacement gas tanks anymore.
So what must you do? You have to replace your tank with another used tank and hope the rollover valves are intact, and then basically hope they stay strong for a while longer. This is an awful situation and I just wanted to make you all aware of it. In my case, I tried fending off the problem using ball point pen internals, epoxy, jb weld, and while each of them worked for a little while, they all eventually stopped working. After doing this repair, the issue has stopped and I am completely happy. Let me know if you have any questions and as always, thank you so much for watching!

I've had the exact same code and evap leak for over 2 years now. I could NEVER find the leak, but I'm sure it's the rollover valve now. Thanks so much for this video. Extremely helpful. Just dropped the tank to install a new skid plate...grrr...gonna have to drop it again. Thanks!
Best of luck! Reach out if you have any questions!
FYI later model TJs have the evap canister in the rear so there are more connections on the passenger side than what you show, just in case folks with a 04 try to do this, they need to be aware. Thanks for posting!
Got it! Thanks for that!
Great video! Just subbed. Glad to see another TJ channel out there.
Cheers 🍻 🍺
GREAT video! Thanks for sharing this info!
Thanks for watching!
OMG I'm dealing with trying to find and clear that same check engine code so I can get it inspected! I changed the gas cap, put in a fuel cleaner and kept driving with new gas hoping it would clear. Going through my 2nd tank of fuel now, hoping it would clear. 😂
Thanks for making this video. I never would have thought to check this.
Bes of luck! Let us know what happens!
This video literally gave me the confidence to do this now!
Awesome, I am glad! Thank you for the support!
@@Garagecouple Hey good video on the e vac leak. A couple of questions. First how did you make a smoke machine to test the lines . How did you find out it was the roll over value. Was it with the smoke machine. And did you drop your tank when you checked your lines with the smoke machine. Thanks your your videos
I just bought my first TJ (1997) and I look forward to tips and any advice you have.
Question around the 13:42 mark you make mention of finding a broken plastic T evap piece, and I have to wonder if that was the source of the leak and not the rollover valve?
Nice Job! Thanks
Thank you too!
Great video as always!
Glad you enjoyed!
i've been pulling out my hair trying to figure this exact problem out. I'm going to give this a try. Thanks.
Its a terrible terrible problem to have lol but fortunately there is a solution
I drive an old Cherokee but I found this interesting. Subbed as well.
Cheers! All the best! Happy jeepin
This may be the problem on mine. Im popping the 0456, 0455 codes for Gross large leak and small leak. Great Video. Only one thing I would have done differently......siphon the gas into the newer tank AFTER I had it mounted up....make it easier to lift an empty tank vs a full one.
I was also looking at possibly trying to replace those rollover valves with ones from a 99-2006 dodge ran 15/25/3500 as alot of Dodge parts interchange with our TJs
Did that ever work for you
I just bought an 01 TJ yesterday with 155k on it. Did my best to make sure it was as. Good as a 20 yr old vehicle could be. Have you done a rebuild on the engine yet? Fingers crossed that I got a good one
Great info, I just picked up a 98 Jeep TJ and cant believe how much I am falling in love with it already. I did just post a video on my channel about it if your interested in having a look.
Don't you LOVE waiting to see if that CEL light comes on?! On my 06 Rubi Unlimited 6 speed the filler neck cracked AND the valve on the passenger side too! I did an insert on the valve and built a new neck while removing the ball and cage piece in the fill neck. Then I bought a ''Flex style'' rad hose to use as the filler hose and it lets the body flex without cracking the neck at the tank. I put a new Bosch pump in while I was in there only to have it fail and light the CEL 200 miles later?! Pulled it out and found the regulator O ring was cut when they built it so I dug one out of my ''collection'' and it has been good for a few thousand now. I NEVER want to drop the tank again!
I was about to hit the Subscribe button until I watched you playing with your bird on camera... That's when you lost me
Thanks buddy
Had this issue. Did the same thing, bought a used tank. Rollover valve on that one broke as well.
If you're creative, you can actually replace the rollover valves in the tank with the current ones for RAM trucks. I need to make a video on it. It's takes a bit to do it tho.
I might just drop 1700 and get a Gen right tank
I've seen that done but it's a lot of qork and I wouldn't want to tamper with the safety system
Thank you for the information . I had no clue there is a problem with finding a vent valve for the fuel tank. Can you tell me the brand name of the OB2 Bluetooth reader? I would like to purchase one for my 2006 Jeep Wrangler TJ. Thanks for taking the time to educate us through your videos!
Really appreciate the kind words! Here is the exact one we use! Cheers! amzn.to/2JWGIsL
Great step by step. I don't have a TJ but I watched the whole video. Cheers!
Thanks for the support as always! Hopefully this video helps others out of the cel cycle lol!
Excellent vid, and many thanks for taking the time to share your experience. VERY helpful for my '01 TJ! New subber.
Cheers! Thanks for the suppprt!
my tank had a busted filler so i found a tank but it had a busted roll over valve , like you said they dont make tj gas tanks so luckily my tj is registered on the reservation so no emissions for it,so i just blocked off the valve and line .wish there was a way to remake tj gas tank it would help alot of people.
Yes absolutely! Lucky you! Thanks for the support!
Great video I have a few questions. 1 how did you make the smoke machine. 2 did you find the leak with the smoke machine. Thanks for your help
Using a sauter iron and mineral oil!
Solder iron?
And then what? Did you make a video about it?
Hello ,great video, i have 1 question i have a 97 tj and coming off the gas tank i have a tee that comes from the roll over valves and a metal and rubber line that is at the front of the engine on drivers side that it appears to be on a bracket with the main fuel line ,does the metal end plug into that tee on the roll over valves or the opposite end thats just rubber??? i started a frame off restoration last june and i am now reasembling stuff,the jeep was basically a yard rig with no fenders, i know one end plugs into the evap canister on the drivers side fender just dont know if its the metal end or the rubber,ps i just got the motor installed with the trani and i watched your pinion angle video and gained some knowledge thank you so much with out people like you were or what would one do! thank you!, Mark!.
Wow, that sounds like a ton of fun! I hope you enjoy every second of the build. Im not really sure about your vehicle, I know they are different on different model years. Good luck!
They sell roll over valves on eBay. Just look it up you'll see.
Not for this model year jeep wrangler. The ones for this gas tank are non-serviceable - trust me - we searched everywhere, spoke with dealer - spoke with countless people. It doesn't exist for the 01 19 gallon tank
I had a 2001 TJ and it would leak around the fuel filter at screw in point top of the gas tank. Just replaced seal an no more leaks.
Nice!!!
Which years are those valves replaceable? I have an 02 with the same problem. The whole top of that valve is somehow melted! I’m having a hard time finding a replacement tank that’s not crazy expensive. Even the dealer can’t order them. But that valve is like $20. How do I know which years are replaceable without needing to find a whole tank?
Just checked the error codes on my tj and P0455 and p0456 showed up. thanks for the video!
Awesome! Good luck! Keep us posted!
If it's leaking why not just glue it closed? or does it need to leak sometime?
Hey Greg, I have an 01 Wrangler, standard Transmission, and the transfer case is dry throughout! I just discovered transmission fluid around the fuel tank vent hose, and it is dripping! Where could it be coming from? No check engine light! I'm stumped!
Thanks!
Wow so strange, I dont know how it could have gotten there! Good luck with the repair!
Thanks for posting. Do you have the link to that code scanner?
Sorry about that! Here it is! amzn.to/2UjNRJu
@@Garagecouple Thank you! Maybe your video will inspire someone to make an aftermarket tank!
@@sa1126 instead of buying a code scanner watch this video to see error codes- th-cam.com/video/IhCJ5knYFwo/w-d-xo.html
I have a Jeep Wrangler 2004 and I went online and found the fuel valve for 20$ .
If the pump works why wouldn’t you just connect 12v to the pump leads. Jumper cables some 10gauge wire and female blade terminals ends
Its the connection thats the issue
They are cross corner from each other. And the sensor leads are in opposite cross corner. Using the female blade connectors crimped to the 10 gauge wire and then attach to the pins And use the jumper cables to get power from the battery to the pigtails attach to the proper polarity. I’ve never dropped a tank with more than a 1/4 tank of fuel. Because I’ve always transferred my fuel to another receptacle The plug has nothing to do with simply supplying power. Even a drill battery will work
Ahh just understood the comment. Good point!
Have you ever had a P0123 code come on the TJ?
Yep! Time to replace the TPS
There are no aftermarket fuel tanks with the rollover value attached? I’m shopping for a tj and I thought it had enough aftermarket support that tanks would be available...
Not to our knowledge! But grab one from a junkyard and hang onto it!
@@Garagecouple crazy! Thank you for the videos and reply, subscribed 👍🏼👍🏼
Appreciate your support! We have a backup gas tank as well! Worth keeping in the garage! Lol! All the best
Out of the literal hundreds of Jeep TJ owners I know, I've never heard of this issue lol... Pro tips for those reading this: Those "rollover valves" are just fuel tank vent valves. You can remove the factory ones (or plug them off) and install generic universal ones for less than $50 a pair. Also, I'm not sure where you looked but, there's replacement fuel tanks all over the web and often found locally through 4x4 shops. Very easily obtained. I would've replaced those hard plastic lines (and any tees etc.) before resorting to a full tank swap. And you didn't let us see it actually fix the problem. No offense man but, I would've trouble shot that more before doing all that work and spending all that money. Hope you got it fixed though!
Unfortunately not true for this model year. It is a non serviceable valve. Look it up on the forums!
Why would you put the gas in the new tank before you install you just have lift it up full of gas?
Hi looking for help. I have 2000 TJ 4.0 130k miles with a Check engine light p0301. I replaced the spark plugs and coil packs with oem ones. I believe the fuel pump regulator is going bad because it takes a few try’s to start but after it does it runs perfectly fine. Could this be the reason I have a code?
Thank you 🙏🏼
Sorry we werent able to help, hope you got this sorted out!
Great video! Thank you and keep Jerry in the vids, he's entertaining.
Haha! Thank you for the kind words! We've gotten mixed comments so we just keep him out :)
Where did you get the tops to your doors?
We ordered them on Amazon. Check out our video on our channel walking through the sliding upper windows :)
in Australia its not an issue at all , never reported as a problem to the dealer network by a customer , must be cold weather related , after market no one has come across this problem either that i know off after 30 years in parts and service
Not cold weather related. A design flaw for a few specific model years.
@@Garagecouple us Aussies must have got the updated versions
I mean..its only on a few years of the tj. Like 99 to 01. It's possible you got a different version
@@Garagecouple possible I had a 99, an 01 and a 2000 and now a 2005
Nice! Have you ever dropped the tank to look at the rollover valves?
My das just traded his dirt bike for one of those but the rear is super shaky when you drive up t
Traded for what?
Where did you get those turn signal lights
We made them ourselves! Full video on our channel!
Hey do you by chance have 2 old shocks? I dont really care what brand..?
We don't, sorry!
How many inches is that Jeep lifted. ?
2.5
Jeep's are made for after market mods, meaning a new after market tank almost same size with after market roll over valve if it did not come with one ,,,or outside roll of over valve,,,, custom made fittings,,
This is true!
I have a 2005 jeep wrangler 4.0 and its throwing the P0340 code. It won't go past 2400 rpms. What do i do ?!?!
I would take it to a mechanic!
id replace the hoses and pump at that point chit! Use the old as a backup...i get it $
good call!
How do u know it just wasnt that “t” line all along ?
Because the vent tubes at the gas tank were clearly leaking and this fixed it
My 01 Jeep tj check engine light goes on and off constantly I was told it was my O2 censor? Anybody else has or have had this problem?
Interesting.. it would be worth changing to see if it fixes. Have you checked what code its throwing ?
Mine comes on and goes off as well, have also been told it’s the O2 censor. Mine also won’t hardly take gas and will sputter when climbing in RPMs everyone and then while making a knocking noise from the gas tank area. Have not replaced censor yet
I would have just hooked 12vdc to the pump. It’ll do the work for you
That's a good option, butwanted to do it manually
Lol. I guess it’s the technician side of me
Is that your therapy bird ? or are you just interpreting what the bird is tell you ? lol
im glad i dont live in a state with smog test or any test for that matter
SOOOO LCUKY!
Put that bird in the house for krists's sake.
the parrot knew it - all the time ;-)
LOL! He was grumpy because I took him out of his warm cage and brought him to the COLD garage at 7am, LOL, not having it!
Ummm my check engine light doesn't work on my 1997 sahara
Time to replace the bulb!
Is that the original motor
Yes
You forgot to record how to install the new hoses on the roll over valve🤦♂️
Can we make a 3D re print?
The issue is its not removable
so all that over a broken t connector.
Non serviceable
just put a newer tank in the spot something that will fit from any car maker on the planet, or a fuel cell like if u race.
Nothing fits directly without a lot of fabrication. Fuel cells are thousands
Dude…. Get Rid of the bird. Jeezzzz
I also have a bottle opener on my license plate. Doesnt work well. I installed a old school coca cola bottle opener near the tail light
Lol thats super cool!
You need to invest in an electric ratchet lol
We have an air ratchet and air tools but choose not to use them because most viewers dont have em
Tip, strangle parrot.
This guy might be wrong pressure test and spray soapy water maybe around the pump
Done and done
lose the bird!
Noted!
Way too many commercials
Eeek
Audio is not good especially with the patriot squawking
.
Appreciate the feedback. We will work on it!
The bird is super annoying. Takes away from whatever message your trying to get across.
Autozone will read your codes and reset your check engine light for free, or lend you an OBD reader for free.
$10 isn't a big investment to have your own, but it's not necessary.
We use one from Amazon, was 5 dollars shipped, link in our shop just search garage couple on amazon
The bird was annoying as I tried to watch and listen. I couldn't watch past the first couple minutes
Sorry about that
Get rid of the friggin’ bird. It’s very annoying and distracting.
I stopped at the annoying parrot.
His name is Jerry
Get rid of that bird! It's like scratching fingernails on a blackboard. Dislike.
Noted
your bird is annoying AF
I'm sure some people think that squawking bird is cute but it's so distracting I stopped watching
Sorry to hear that..The bird goes way before the important stuff :)
Garage Couple watches video second time around that is a super bummer they dont make tanks no more, wonder if you can buy an aftermarket replacement or a plug and play fuel cell ?
You could buy those, but they coat over 1500 and may not pass state inspection. Brutal.
Garage Couple did you ever think of putting your own brass valve into the tank, sandwiched with washers & rubber gasket like drill out the plastic fitting reach into the tank put a 90 degree air fitting that will attach to the rubber return hose but seal the hole with large washers and rubber gasket very similar design on steel wheels and the metal valve stem air fittings
Yeah, I did think about it. It seemed like a lot of work and there were no guarantees that it would work. These systems detect tiny little leaks and to be honest I didn't want to see the check engine light on anymore so I replaced it with this tank.
Get rid of the effing parrot!! Dislike!
Booooo
Those birds can really be characters, I always wonder what's going thru their head?
They're like having an adult human around. They're so incredibly intelligent.
why the bird dude seriously
