Definitely trying to connect these vacuum lines BEFORE bolting the upper intake back on. Got that little tidbit of info off YouTube yesterday… AFTER putting it on without the vacuum lines on. Forehead slapped, doh!!Yeah, that hose goes to the long metal tube under the manifold curve. Bitch to get to so put that on prior to the upper plenum. Oopps! Too late, no you have to go fishing. If you forgot and left it wide open, you'll have one hell of a vacuum leak.
