Charcoal Canister Necessary?

I just installed a custom cold air intake, and I had to re-locate the charcoal canister so that I could fit the new K&N filter into that area. The charcoal canister right now is sitting by the A/C condensor on the passenger side. I bought new vacumn lines so it could reach that far. There are markings on the canister for pcv and the fuel pump/tank.....so I'm concerned about this gadget....thats why I'd like to know if its really necessary to keep this canister hooked up and under the hood? What would happen if I was to take it out completely, and plug up those vacumn lines that goes to it? I dont want the car to run rich/lean etc....could anyone advise me on this? I still have the AIR system hooked up to the manifolds too, if that has anything to do with it.

It's necessary if you have emissions testing. If your not concerned with that then no you do not.

The fuel vapor hose does need to be placed somewhere the fuel vapors can exit the car. Like underneath it. Then you can plug the rest of the hoses and put them where you like.

If you do this be prepared for a gas smell. Also wouldnt be a good idea to plug the line as you need a vent there. A trick I heard works well is get a crappy plastic import fuel filter and put it on the end and works great. See imports are good for something.

Thanks for the quick replies everyone. I may just keep the canister, or vent it with those import filters....but which filters should I use if I was going to do that? Would those APC filters be good enough or should I go for the actual fuel filter off a Honda or something?

Any filter will do. I just said import filter because their common and cheap.

Cool. Just making sure the r*ce stuff would work for this. I might decide to keep the canister on though....not sure yet. I'm worried about seeing tons of smoke comming out of my exhaust if i remove this for some reason. I should only be driving the car another year anyway, at which time I plan to take her off the road and start working on it as a project car. Thanks again.
