fuel vapor canister

[slickxman]

Fuel vapor canister can i do away with this when i change 2 a barrel weber carb on 84 ranger 2.3. Without losing fuel economy or anything. i have removed all emission stuff. just wasny sure if that was something you actually needed.

a small search revealed some answers, this canister is for emissions and looks like it wont hurt your economy if removed, but since its dealing with vapors that get reintroduced to the air intake i wouldn't know how to proceed.

I would say leave it connected if the carb you are using has an inlet for it. The canister gets vapours from the gas tank that are then drawn into the carb to be burned (usually at startup). If the vapours have no place to go you gas tank will blow up...lol

Well, actually, on a carbed vehicle this can work backwards if your float is not set correctly...I put a clear plastic tube on mine and when my needle slipped out of the float some of the excess gas drained down to the canister...but that doesn't make its way back to the gas tank (as I'd first thought was happening)...

Removing the evap system (of which the carbon canister is a part) is the automotive equivalent of cutting off your nose to spite your face. It doesn't hurt a darn thing in terms of power or performace, but it does capture evaporating fuel and store it for use instead of letting it go out into the atmosphere, wasted.

In my experience only two people genuinely suggest it. The first are the kind who wear tin-foil hats and swear that fuel injection is a ploy by the government and CIA to spy on us. The other kind are people who know so little about cars that they shouldn't even be allowed in the tool department at Sears.

Note to the OP, you fall into neither category since you just asked what it did, instead of going and ripping it off without thinking.

Thanks to all the replies. i think I'm gonna leave it. not sure if the weber carb will have a place for it. Can't get the carb and conversion kit till next week. . if the carb doesn't what do i just put a filter on the line going to the gas tank or would there be any harm in tapping into the
breather to suck theh fuel vapor?

Any ported vacuum source would be good enough on an EFI setup. I'm not sure exactly how it goes with a carb.

Most of the ones I've seen do have an opening for that purpose...what carb are you getting? If you see a nozzle on one side near the fuel inlet (usually 90* angle between the two) and near the top then that's what it would be for. No other inlets on the top of the carb for anything else...from what I've seen anyway.

The hose on mine is 1/2" approximately, and I'm pretty sure it is that size all the way to the canister...

JUST BE CAREFUL THAT YOU DON'T TURN YOUR GAS TANK INTO A FLAMETHROWER....find a carb/diagram that uses an evap. canister so you can run the hoses safely.
