I have a Vac Manifold I am installing to clean things up a bit .... Whats the best spot to get vacuum from. I see the brake booster line is a common choice, I wanted to run the vac manifold in line but the 2nd end has a cap on it? Anyone know that thread pitch or done that?

^^^ Its a little manifold you hook one source of vacuum up to and it gives you 6 sources of vacuum so all your vacuum lines are connected to one spot instead of all over.

well, while this thread is back from the dead, here's where my thread of my vacuum manifold setup. i dont have pics of where i newly tapped it, but if you look at the last engine bay pic where the brake booster line goes down, i tapped it right at after that [top] bend.
actually if its a golden eagle its not NPT on the ends of it. It requires a special o-ring seal nipple as i recall. I got mine from a company that builds /repairs hoses of ALL sorts shapes and sizes. Was only a coupel dollars. I could take a picture if someone wants it?

I had a golden eagle, the actual thread pitch is 3/8 NPT. That has nothing to do with the hose size. You can have a 3/8 NPT (large) thread pitched fitting with any sized barb for almost any sized hose, just depends on your needs. The reason it uses o-rings is because the NPT fittings aren't self sealing the same way that AN fittings are.
