An update on the saga. See for the backstory.
My 2000 EVC with the GM retrofitted vapor canister was due for a smog check. I took it to the local guy who is friendly and has seen the van before, and asked him "will this pass"? He said that it would not pass visual inspection, but there is a referee process one could use to try to get approval. However, he's mostly seen people trying to get non OEM catalytic converters approved, and has never heard of anybody getting a non-OEM vapor canister approved. His opinion was that it would be difficult, because (A) it's a GM part and (B) it's in a different location than stock.
In any case, I told him that I had the original canister which was in (somewhat) working condition. He said that if I brought the van in with no OBD II faults and all readiness codes set, with the OEM canister installed, it would pass.
So that's what I did. I left the GM canister in place, zip tied the hoses up out of the way, and re-installed the WV canister. It took about 30 minutes to swap it and pass smog.
I have 2 years till the next smog check, so that gives some time to decide what to do next - perhaps some third party will start making these parts again? Perhaps I'll try the referee process?
