interesting mr. b.

i have a jan 74 build car.
plastic cannister.
and rear firewall mount.
i don't know if that helps as i am not sure when plastic cannister kicks in.

when it comes to the other lines of vw cars, they seem to plumb them the same, regardless of whether its earlier metal or later plastic from what i can tell.

you have greater insight into the cannister itself, i've never seen inside one physically.
just photos such as yours.

i think your theory is probably pretty sound on how the airflow works.
i'd have to think further about that and give it some thought.

but.....

the 1.8s are consistent with VW practice from 70 on with the introduction of the system.
to discount the 1.8 plumbing would be to discount the plumbing arrangement on a vast no. of vws also produced during that time period and a decade of vw emissions tech literature? because they all work the way the 1.8 is plumbed. all of them. and they all have cannisters located near the engine bay. i think that is the key to understanding this. the shift to the engine bay.

i don't think we have an answer yet.
