[Chevelle-list] Manifold vacuum fitting?

[Pelle Andersson]

I've got a few Q:s about the vacuum sources on my Chevelle -71 402 BB!   1. Where is the vacuum source to the TH350 located originally? 2. Where is the vacuum source to the Power Brakes located originally?   Right now they're both connected to a fitting on top of the manifold which can support two vacuum hoses, I guess it should be that way?   How on earth am I supposed to get any hoses to connect properly to those two flimsy little fittings without having a vacuum leak? The hose fittings are approx 8mm long and Ø4mm!!!     Pelle
