Removing Charcoal canister on 87 Iroc
Car is registered as a street rod so I don't have to worry about it passing emissions. My main goal is to clean up the engine bay of some of the excessive wiring & hoses and create some more space under the hood as I have a supercharger and a vacuum reservoir. There are multiple lines going to and from the canister, what can I remove, what will need to be rerouted and where, without screwing anything up? I have also removed the smog pump. The A.I.R. system was removed when I got the car & it has non-A.I.R. SLP headers w/ a gutted cat.

It helps keep the gas fume smell away and the gas take pressure correct.
My advice is to keep it but move it to behind the front bumper support.
Granted my car has more room than most but it used to have the correct bumper support in there.

I've got an intercooler there so that wouldn't work. It's just an awful lot of hoses & crap vs. the older 70's cars...although they were more basic in all aspects too.

Get rid of all of it. You don't need it. I don't have it on my car and lots of other people on here has done the same!
