You guys know what this is, it's the plastic bottle beneath a metal cover on the inside of the driver’s side quarter panel.

My rig was missing this and as a result, my tanks pressureize during the summer and exspell gas so I'm trying to get this hooked up. Bought a tank and cover now trying to figure out what I'm mising?

My vapor separator has 4 tubes that exit the bottom but I read there should be a 5th hooked up somewhere and maybe a valve but where dones it run to/from? I know I need a charcoal canister but the 5th line has me stumped. Do I have the wrong vapor separator for two tanks?


My rig a a collection of parts off many different years so I'm not sure what I should have vs. do have. I have two fuel tanks the aux tank only had a hookup for one hose from the vapor separator and the main tank don't have any. Should be two lines to each tank correct?

Bought mine out of the "parts for sale" section on this board. I'm going to pull the charcoal canister (from an F150 or full size Bronco) att he pick and pull.

The 76 and 77 bronco s had it outside the cab so you won't get the fumes inside one spot is in the engine compartment on the passenger side of the fire wall and the other spot is on the frame behind the inner fender on the passenger side. Like 390 says. Get one from any ford car or truck they are real similar might save you a little hassle

Yeah, I would think no one would want any gasoline in the cab with them. I got rid of mine that was leaking and used a large reversed fuel filter and kept the charcoal cannister to accomplish a similar thing. Works great, no gas smell.
