You're going to think i'm mad but i've only just noticed this thing, remember only got my truck in Jan and never owned one before plus i've not had cause to look down there before now

looks like there should be two vacuum hoses comming off the top or something...any ideas?

Andy4639 · 03-27-2008, 07:03 PM

I can't answer where the hoses go but the canister is a charcol for the gas tank vent.

I think that started in 71. More emissions stuff.

Thanks you guys...now all I need to know is how do I find out if it's working or not or if I even need it.

If your using the engine described in your signature in the truck, it probably does not have the emissions provisions to hook up to the canister (aftermarket carb.)

Thanks streetstar that makes sense...maybe I should just leave it alone and forget about it.

airdale94 · 03-27-2008, 09:15 PM

The big hose goes to the gas tank (vent) the other hoses goes to a vaccum switch and the carburator.

Any one know where to get a new filter for it?

hvychve · 03-27-2008, 10:20 PM

The way gas prices are today, I think I would capture all I could , even the vapors, that is what that thing does, it stores vapors into the charcoal, and than once started , your ported vacuum pulls the vapors from the canister to reburn, This is emission related and has no affect on performance, it actuallly can benefit you some........ one line to tank and the other line to a ported supply port on carb....

eightbanger · 03-27-2008, 10:44 PM

Those vapors would come in handy

maybe i'll use it to keep beer in and run that hose up to the dash.

Everybody knows it hard alcohol in the washer bottle, right? You run the squirter hose into the cab just push the button to dispense it. Beer would be nice, but the carbonation and bouncing would cause problems.

I knew a guy in high school that tried beer in his washer bottle. Only thing was it was still in his engine compartment. By the time he drove down the block the beer was a little warm. And it took him forever to fill up his cup. We tried to tell him to use vodka, but he liked his beer.... Oh and it tasted like rubber btw....
