Vapor/Charcoal Cannister

Yeah, I suppose the vacuum-activated purge isn't necessary, right? Though I think I read that it helps with hot start issues, or starting issues in general.

The purge port (to the PCV) on my canister is small, but the out you have is large, and it says in one of the manuals it should be large. I'm wondering if I have an aftermarket part in there... I bought a small hose and was going to T it into the PCV hose anyway and see what happens.
Look closely on the right hand side of the picture, you can see I put a vacuum activated purge valve in line since the can did not come with one

My purge line is about 7/16th BUT the port on the cannister was smaller, maybe 3/16?

I just put a vacuum cap on there, cut the end off and used it as a bushing to get the line to match my PCV line
