Charcoal canister removal
 

Pulling the charcoal canister off, what do I do with the lines to minimize fuel odor? can they be capped or must they be allowed to vent to atmosphere?

if you want to minimize the smell of gas you might wanna think about leaving it on.

The tank MUST be kept in a purged condition to avoid the tank blowing up when the sending unit inside the tank arcs (which they all do). If you remove the carbon canister, be sure you know how to provide for a proper tank purge line.

how about i just send the charcoal canister lines into the intake? Would that cause any problems?

Oh crap! How do I do that? Mine was removed when my carb was installed...

I don't want my car to blow up.

Does the cannister make any difference in an se? i want to take mine out... i tried painting it for one and it looks bad, and for two i'm taking out anything unnessary from under my hood.

Leave the canaster in..... I relocated mine to where the cold start assist used to be..... But if you are concered about the looks, swap it with the second gen canaster.

It's plastic and alot better looking! LOL One less rusty part!

If it's a 12A engine, buy a '79 air canister hat, it has the charcoal built into the top of it with a little hose coming out of it for the vent lines.

I did the same as jimmy, put it where the sub zero tank was, looks good IMO. If it weren't so rusty i'd paint it black, but whatever.

Good idea.
Then all you have to do is run a hose from the carbon canister in the lid to one of the nipples on the air/oil seperator tube. Install a reducer tee in the middle of it and connect the tank purge line to it. That will provide enough vacuum to keep the tank purged. Also a good idea to install some sort of a breather filter on the other nipple on the oil tube. I used a little blue anodized filter that I bought at a local auto parts store, but an old fuel filter will work too. That line is the ONLY vacuum line on my motor, other than the brake booster connection.

sounds like a possiblility to me... anyone?

:confused: :confused:
WG, how sure are you on this? If you have a vacuum in the tank, then the pump will have to work super hard to pump fuel. On one of my cars the tanks sucks air when I open the cap to fill it, on the other it doesnt. :confused: :confused: And what causes the vacuum to build?:confused: :confused:

yeah, my tank goes "psssshhht" every time I take off the gas cap... all the other rex's I've had did the same... hmm.

LOL, I'm REAL sure, Carl.
There isn't a whole bunch of vacuum, remember that it only needs to be kept in an air-starved condition. The tank gets it's little bit of vacuum via the charcoal canister. When the motor is running, the charcoal canister gets purged by a vacuum line that connects to the charcoal canister. When the motor is turned off, the charcoal absorbs the fumes from the tank. If you check out a vacuum diagram, you'll see how needlessly complicated it is.

Damn, you ARE ignorant, aren't you?;) -WG

Ok smartass, now I know your misleading me. :) There is NO vacuum line to the cannister. :p:
