OK...in the process of replacing my charcoal canister, as all my hoses, the Y and the tank itself was shot. Using PorKen's post as a Guide.

A few facts about my '82:
- Has a SC with all air intake lines replaced.
- Is an AC delete.
- Has an Euro TB.

What I've found when I trace the hoses from the existing canister:
- The larger hose from the Y goes to a vacuum pod sitting within the engine compartment. It's not connected to anything else.
- The smaller hose from the Y goes into the engine compartment, but right now I can't trace it as I don't have my lift bars high enough ()
- The final hose terminates to atmosphere inside the engine compartment. It was sitting up against the firewall without being connected to anything.

If I'm following Ken's post correctly, this basically means that the original canister (assuming it was functional) would take vapors from the tank and route them back to the atmosphere. Correct?

that hose should have been connected to the intake tract.

Which one? The one against the firewall?

If so, where does it connect? I've been going through the PET and some of the other posts on the topic (of which there are many), but can't seem to find the terminating end.

(and thank you!)

If you have a new replacement charcoal canister, it may (mine did) have 3 connections. MOTOR, LUFT and TANK. If it is a newer version you won't need the plastic Y connector I believe. One connection goes to the engine intake connection (MOTOR), one connects to the gas tank expansion tank (TANK) and the last one (LUFT) goes to the fresh air supply hardline. The TANK and LUFT (air) hoses connect to the hardline on the firewall (should be 4 total, the other two are fuel supply and return). Your car may have a plumbing diagram label inside the hood I believe? Someone please check my info as I am away from car and WSM.

Yup. I've got the newer one, so was planning on deleting the Y.

What you write is consistent with the research I've done here on RL, but what I'm trying to decipher/undo is some of the prior work that was done on the car.

The only line that appears to be connected according to the PET is the one going to the tank. The other two terminate to a pod and to atmosphere.

OK. I'm at a bit of a loss here and hoping that the wonderful community here can help.

I've done a ton of reading / searching since my last post, and here's what I've been able to determine (or at least I think I've been able to determine):

- I don't think there's a hardline vent line that goes to my rear bumper. It appears that might be on later models, as those show 4 hard lines going to the rear, whereas mine has 3.
- One of the lines that was coming off the original Y was going to the overflow tank. This is expected.
- One of the lines that was coming off the original Y was going to a vacuum pod which would go to the TB and the A/C. The PO has basically tapped this line off since there's no A/C and he replaced the TB.
- The one remaining line that was open to the atmosphere in the engine compartment is supposed to go to the Airbox, as shown in the pic on the thread here. However, since he replaced all air intake lines due to the SC, no such inlet exists.

I'm really not liking the vapor venting to the engine compartment (maybe unfounded), which I think leaves me with two options:

1. Create an inlet on the replacement air intake to allow the canister to connect to it. Not sure if I really want to mess with the aftermarket setup.
2. Route the atmosphere port on the Charcoal Canister to the rear of the car. This would require me running a new hard line parallel to the existing 3 that go along the passenger side.

Is either option better than another? Am I making a mountain out of a molehill out of my concern of having it vent to the engine compartment?

Thanks for the input, as always.
