Very interesting! Thumbs up for insisting on a roll over valve and not just for rolling over. As a dealer tech for decades, the roll over valve is part of the vent system because , filling the tank, fuel rich air exists the tank to allow liquid fuel in. Most OEM, like GM & others, use a liquid floating type. When liquid fuel reaches it, it lifts and spring assisted but seals. This action pushes raw fuel fuel up the filler neck and shuts off the pumping action when it reaches the aspirator tube inside the nozzle. There are wires from the pumps nozzle for ground and shut off inside the rubber hose. If the “Ball” does not float or goes to a simple gas line up the roll cage, makes a “U” turn then terminates, the smell of gas will fill the garage as it expands and contracts. Using an activated carbon canister will capture these organic hydrocarbons. It creates a mild exothermic reaction. Once using or pulling the fuel level down, it will allow air in, endothermic reaction, and keeps the tank for collapsing in a vacuum. Canister are sized by the fuel tank. Get a used one from a GM truck in the bone yard and glue some cube of foam (Seat Upholstery Foam) to the canisters “Vent” pipe. Or, attach a hose and place a lawnmower fuel filter on the end. Purge fitting can be plugged unless you program the PCM to purge. No purge cold, idle or upon deceleration as injectors shut off. The roll over valve is connected to “Tank” fitting. The only time “Vent” & “Purge” is closed during “EVAP” testing for leaks. We don’t want hydrocarbons escaping and running off to have fun by the pool or watching the game! Hell No! Hide the canister? Run roll over valve line up high, loop down, go under the bed or somewhere to mount. The return line (If used) but returns normally to the bucket where the pump is. The bucket type are call modular resivour assembly or MRA. To avoid aerating the fuel, dropping volume which in turn drop volume and misfire. That is a no, no in the car world. They actually had the misfire counter less sensitive in 1997. On many models, the output high pressure side had a “Tee” in this line. They placed a Venturi valve made of brass, cast into the plastic. It had a 0.030” hole and bell shaped. It creates a low pressure in a passage to the bottom filter. This pulled fuel into the bucket, cooled the pump and kept a supply of fuel at the ready. They had a float that lifted to open a dump to maintain the the level of fuel inside the bucket. Fuel pumps are designed with two rotors where the first one pump fuel in and had bleed holes to allow air out. The second rotor creates the volume. Without volume, you have low pressure. It passes thru the center of the pump, out the top, pass a check valve to hold fuel in the lines while the regulator blocks off return when pressure drops as shut off. Just some info.

Matt, you should also include that in case someone was to build/design their own fuel cell to keep in mind as to what type of sending system they are going to use. as it is not uncommon for someone to use the stock unit. however on some vehicles the return line us not only used to return fuel and displace pressure, it is also used to cool the electric fuel pump.
I found a ring but it’s not the same exact one that they used in the video. Instead of being welded on this one is bolted on with a gasket. www.anyprices.com/genright-fuel-pump-adapter-117225/price-comparison.html
that is not true, the fuel cell foam last way longer then a year, all the technology came from the aircraft industry , and small aircraft fuel cells and foam last a very long time the idea is that a real fuel cell has the bladder that will bend and squish in the event of a serious accident. the foam is used to stop sloshing and to slow down leakage in the event of a rip in the cell. anything else with out a bladder or foam is just a gas tank not a fuel cell. this is from fuel safe... Fuel Safe Fuel Cell Guidelines Here at Fuel Safe Systems, we work tirelessly to provide the highest level of quality, performance and durability. Everything we manufacture is built to withstand the extreme demands our customers place on our products. Safety fuel cells are out of sight so they tend to be forgotten. Fuel cells have a finite life span. The environment can greatly affect the cell’s longevity. The typical lifespan of a fuel cell is between 8 and 10 years, although all sanctioning bodies limit use to 5 years from the date of manufacture. By following a few simple guidelines and inspecting your fuel cell on a regular basis, you can ensure that the performance and safety of your vehicle will remain intact. •Avoid fuel additives •Do not store fuel in the cell for long periods •Do not expose the cell to harsh chemicals •Do not use solvents on the cell •Store your bladder in a cool dry place, out of direct sunlight •Inspect the interior and exterior of your cell once a year
+keith wilson you just proved my point with your own comment! You claim foam last longer than a year but in the last paragraph you say not to store fuel in the cell, and to inspect the interior once a year. Now why would they have those guidelines if the foam isn't breaking down?? It may last for more than a year, but only if you pulled fuel after every ride and clean the foam once a year. Which isn't going to happen for most people.
+BleepinJeep well i know from my 1st hand.. i have raced in the desert for 20 plus yrs and the foam has never broke down but the bladder does need replaced after 8 to ten yrs, but you are calling something that is just a custom gas tank a fuel cell, its just a gas tank is my point.. a custom one but still just a gas tank not a cell.. and i really like your channel and all the stuff you do, but this one you are calling something that it is not its a gas tank not a fuel cell period
+BleepinJeep also those were not my words but the words of fuelsafe.. but i have never drained a tank and we race ever 6-8 weeks and some time 6 months.. my guess would be the storage thing would because of the fuels can break down over time and with so much eythenol now days its not the best for the bladder... once again my whole point is that that is not a fuel cell, its a custom gas tank.. a very sweet looking one though..
+keith wilson Technically by definition, you're just running a custom gas tank on your rigs as well. An actual fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction of positively charged hydrogen ions with oxygen or another oxidizing agent. As far as your estimates on the life span of the bladder and foam, ATL racing says bladders last 5 years. They also say the foam should be inspected several times a year and replaced every 2 years. Oxygen bearing fuels does effect safety foam more. There is a lot of cases where the foam has broken down and clogged up fuel pumps and filters also. A lot of it is having to buy premium foam vs budget foam, one will last longer than the other but both is a lot more work having to check it over the lifespan of the vehicle. Really with this rig being a crawler and a full cage around the vehicle, it should be completely fine.
+TheAmericanUhate well fuel safe says other wise and i would say they are the pioneer in the market, maybe they just have a better product i dont know but the the fuel cell we are talking about have been around way before the kind you are refering to.. but tomato .... so i was just saying what he has is a gas tank, zero safty involved and not a fuel cell, and in life somethings share names but are not related what so ever..
Just came across some vids about running engines on gasoline vapour, it may be something you would be interested in looking into further for this project or on a future one. Would greatly increase your MPG and allow you to run for hours on just a small amount of gasoline. 2 videos here of engines running : ruclips.net/video/RNUfryhT4H8/видео.html ruclips.net/video/MsFRaV4zKEQ/видео.html Great videos buddy, keep them coming!

I can really appreciate how much time that took tig welding. definitely worth it, turned out awesome?
!*
All the Bleepin Jeep guys need their own minion thumbnail to show who is gonna be in the video. I lost my shit when I first saw yours
That thumbnail!!!! So good. Thanks for the info too, looking to install a fuel cell soon.
Wow! I didn't know anything about fuel cells before watching this. Your videos are gold! Keep them coming!
Definitely helpful feel more confident putting an aftermarket cell in my wj
thanks for the update and informative post. Crawler is coming together nicely. Cant wait to see it in action, hell of a job thanks for sharing.
Skill n patient..skill n soul...how awesome??!??

Where did you get the attachment so you can use the stock fuel pump?
I been following this build pretty good. It's pretty interesting.
That cover pic is killer LOL
God I love tig welding, one of my favorite things to do. Awesome fuel cell man!
Could you help me out with sourcing the aluminum ring with threads to mount the pump? I can't find one to save my life
I found a ring but it’s not the same exact one that they used in the video. Instead of being welded on this one is bolted on with a gasket.
www.anyprices.com/genright-fuel-pump-adapter-117225/price-comparison.html
I don't know why but the minion yous creep me the hell out haha
I agree lmao
best intro ever!!!! actually laughed out loud
awesome video
thats great! plus you wont be using the gas as much going down hill, i need too practice some aluminum welding
he makes welding tig look so easy!
Good information. Thanks!!!
Man that's badass! That's fukkn cool that you made that!!
you should check out the holley hydra mat... that will eliminate the need for the sump in the tank
Wow that hydra mat is a game changer for sure
Matt, the minion thumbnail is the BEST. I spit my drink out when I saw it...hahaha.
Anyone know where I can find one of those weld on jeep tj fuel pump rings?
Amazing video
A lot of information. Thanks
awsome job mat godbless
weld it when the fuel is in, that is the real chalange
;-)
my dad's jeep had foam in the tank and it took up so much of the tank it only held a few gallons
Great video!
What brand and model mig welder and plasma do you have?
Also, keep the xj blue!
+mike e millermatic 185 and hypertherm 45
Ever heard of an hho welding rig?
Hey Matt where did you get that weld on ring for your fuel pump at
Nate WJ genright is the only place I can find them.
Where can I find that ball valve?
Aluminum is definitely my favorite metal to tig
Where did you get your threaded aftermarket ring for the fuel cell?
+Mathieu Genest genright
@@bleepinjeep do you happen to remember the p/n for that ring. looks like what they have now is different bolt-in style
If there is no bladder,foam or baffles it is a gas tank.
Where did you get the ring for the fuel pump ?
+Norman Murray its from Genright

You have a gas tank, not a fuel cell

Totally a fuel cell, it has baffles and is for off-road use.
It's a giant motorcycle gas tank, so sorta yeah.
