I did a search on this and i am rather confused, which line do i need to let vent and which do i cap off? how do i let one vent without the risk of explosion? How do i cap the line off?

not sure why you would want to do that.... It's there for a very good reason.

I want to take out everything i can from the engine bay.

Edit: i have one other question, there's a container that is below where the washer fluid bottle was, under where the cruise was, and beside the charcoal cannister in a corner. What is this? it has a motor on the bottle and two lines. It appears to be full of coolant, i don't know where the exiting line went (i didn't label anything before pulling my motor, huge mistake).

It's an EFI motor. Unless you go with some sort of carb setup, you'll always have ugly hoses and other crap such as sensors in your engine bay. I'd leave it alone if I were you unless you like water mixing in with your oil.

That bottle is the subzero bottle and motor to help the car start when the weather is really cold (under zero). If you are not in alaska, u don't need it.

One more thing, are the two vacuum switches with the vacuum lines that ran to my cruise control and acv removable? obviously i will cap off the ends.

Yeah the resivoir full of coolant under the washer resivoir is for the "sub zero fluid" which is (according to the Heynes I think) 90% etheline-glycol based coolant, 10% distilled water. Very few people drive their FBs in winter, so it's not used. I plan to keep mine in there, but convert it to a two-stroke resivoir using the adapter that attaches to the OMP. I figure it's much better than trying to fab a resivoir, and keeping the useless sub-zero fluid thingy. Hell, I can't even figure out where my sub-zero hose is supposed to go! I looked at Eric's car and it goes into the carb.. but I've got an '82 carb on there now, and I don't think it has spot for it.

Anyone know if '82s had sub-zero ?

My '82 had it...

Back to the charcoal cannister for another question. I find no maintenence recommendation for when it needs replacement. Any idea of if its useful life and if so the cost? I pulled it out of the metal container but being black and charcoal it is hard to tell what condition it is in. Is its purpose to remove gas vapors from the underhood area? Mine is probably original on the '85 SE. Thanks.

The charcoal filter is there for safety... gets rid of fuel vapors to keep stuff from potentially blowing up.

No it traps fuel vapor for emissions purposes. You could route the vent to a safe place (like the air cleaner housing) so the fumes dont build up.

Crap I meant to edit, not quote, why wont it let me delete this post?

On the SA models the carbon canister is in the aircleaner lid. This is to absorb fuel vapors from both the tank purge line and the carb after the engine is shut off. This also helps keep your garage and the car's interior from reeking of gas. While the engine is running, the vapors are drawn into the intake and the carbon doesn't really absorb the vapors. I don't really see how this effects emissions, myself, but maybe I'm missing something in the later models... Regardless of the year, it's important to maintain the tank purge line as it keeps the fuel tank in an overrich condition, keeping it from blowing up when the wiper on the sending unit arcs (which is normal).

The charcoal cannister should be fine unless you have already observed leakage or problems with it.

It's considered an emission component because it is not letting raw gas fumes (HCs) get into the atmosphere. The carbon mesh lightly bonds the fuel vapors which are pulled into the carb upon start-up or the doghouse in his case.

Wankelguy

Makes sense (in an EPA kind of way). Kinda like the rubber fume sucking thingies on the gas nozzles in Kalifornia, eh?

Exactly WG, you got it.
