i only know our cars starbear.
i don't know anything in detail about the earlier cars.

i believe mr. b is correct in his assertion, but that applies to the earlier cars is what i think.

i am as interested as mr. b in getting these technically right and mr. b has a wealth of information on his website and in his head.

i've dug out more of my material that i had filed away from last year.

i've now got a hunch about what goes on.

2 things.

1. VW has always been consistent in its plumbing and approach to the charcoal cannister.
what is important to notice is that the cannister in all vws, beetles, kombis(buses) type 3s, 412s, things etc is always at the rear of the car with the engine.

2. porsche did do the cannisters plumbed the way mr. b says they are plumbed.
i think the early 914s up to around the start of the 74 model is the porsche designed system that was in the 911s as well, that system is characterised by the cannister being in the front of the car near the gas tank.

i think in the 74 914s, the 1.8s at least, when they shift the cannister to the engine bay they go over to the vw system.

i will post some more material now from both vw and from porsche.
these are technical manuals from vw which i think i got off the samba site a year ago when i was looking into this. the porsche diagrams i may have found on pelican parts forums and are from the factory manual, i dug these up a year ago too.
