Yes, it does but I don't remember exactly where it attaches.

If you need, I might be able to dig up some pics or diagrams to post.

Thanks for the offer but I'm just curious. Seeing that check valve over there vs where it is on my gen 1 got my attention.

didnt need any tools, got the line from amazon and it is a high temp silicone hose. Flexible like rubber and easy to work with. Just a question, does that check valve ever need replaced? Thanks

Possibly, they are not hard to find so someone's buying them. I was working on my vac system and can tell you that sucking more than 20 lbs with a MightyVac will ruin it. They're easy to test with your mouth and should only let air through towards the manifold. I bought a Dorman to replace mine and it was bad from the start so I got one like is shown in that picture that is supposed to be genuine GM and it works.
