Rollover Valve Install 

I hope you guys are having a great weekend, have a great week!

I would be using a carbon canister & enable purge if your running a “LS” an PCM. This set up will fill the garage with gas fumes. A true roll-over valve is misunderstood and sold for racing only. The valve you need seals the tank when liquid fuel hits it. The aftermarket tanks don’t have a bump on top to trap fuel rich air inside as refueling. The vent side goes into the vent inlet of a carbon canister and holds raw hydrocarbons inside the canister as you paid for it. Most tanks will have a hose connector that can go high inside the bed, make connection to the filler neck. This roll over valve shuts off when liquid gas hits it, forces raw gas to backup into the filler neck and hit the aspirator tube in the pumps nozzle to shut off refueling. Purge goes to engine intakes purge valve. Tank vent inlet is open all of the time until PCM testing, then shut off and close. This feature is disabled for EVAP testing if PCM controller. Best of luck as even changes in the air temp in the garage will cause gas fumes. If you have a gas water heater or gas forced air furnace in the garage, the chance of combustion is there.

Great vidio and damb good tunes,thank you sir and have a blessed day América

My concern is water getting in. I was just looking at this same vent today for my 84/78 squarebody.

Dave that is a great safety feature that a lot of people forget about. I was planning on adding one to mine and was just going to run it up the frame rail similar to what you have done but hide it in the tail light socket on the Jimmy on the right side and run the axle vent up to the other side!

Getting close to 10k subs!! CONGRATS

My buddy had one of these installed when he went to moab... he managed to trigger it coming down dragons tongue... killed His Jeep in the middle of it 😂

noice I got a k10

Great video, i was looking for something like this 👍🏻👍🏻👍🏻 , info on the valve ? Ty

2005 Chevy Blazer rollover dial I can't get the stupid big hugs off does anybody know there's a special tool to be used AutoZone and O'Reilly's have no idea what I'm talking about

Did your tank have an existing line exiting the tank to use for the vent or did you add a line?

What did you use for a fuel door/gas cap through the bed I’m in the process of putting a blazer tank in my 1984 k2500 gmc ?

does this help with a fuel tank that constantly burps when filling up? when the pump cuts off the fuel flow and takes forever to fill your tank?

nice stuff. What you wheeling in Moab?

So does that valve let air in and out?
