HVAC check valve

[Bunky]

I have a 1986 Pontiac Grand prix 3.8 that I need a check valve for. It's in the 3/8 vac line that runs from the carb to the vapor cannister. Dorman shows one but it isn't the same. GM part # 25518739 shows discontinued. Can't seem to find one anywhere, even junk yards. Is there an alternative. Any help would be appreciated. Thanks.

Found one here;

Doesn't state 'not in stock'.

If you mean canister purge valve. Rock auto has them for $7 to $12 bucks.
