Very helpful responses folks and thanks for the pmails. I will inspect the
vent hose from bottom of canister. It indeed vents to atmosphere. I may
also try removing the hose at canister inlet.
Dennis: ill google up that part number. Much thanks. Is the lack of venting
at new canister a potential problem in that there is no fail safe? (Then
again, some vanagons already have EVAP "venting" in the form of poor
maintenance. ;). Ha ha. )
The engine is running ok now but I'd like to address this issue soon. The
forestry roads are tempting..... Given the noisy state parks I'm
encountering. ;)
Heat, engine load (long grade), small tank outlet not withstanding,
my Jetta engine management operates the purge valve in a series
of short pulses at idle and possibly at other RPMs but if I'm not
mistaken, the stock WBX purge valve allows air to be constantly pulled soon
after idle. Maybe there's subtle differences between the Mk 3 Jetta and
vanagon fuel tank and EVAP ?
I don't recall seeing a purge valve on my vanagon while it was still in OEM
air cooled form. I'll read my Bentley.
Neil.
