Is this the intake manifold vacuum?

Fitz68 said

Another dumb question for all you pro's out there. I'm changing out my manual drum brakes on my 68 dart (318ci) and converting to power and disc in the front. I'm trying to figure out where the booster vacuum hose would connect to on the intake manifold. Is what I have circled where I would connect it? It seems like it's a valve that has like 5 outlets and two of them are just capped. Could I use one of them?

Yes, that's intake manifold vacuum from that "port", but the brakes need a larger diameter hoses (I can't remember the exact size, but I want to say like 5/16" diameter, most of the little "arms" coming off of that port are closer to 1/8" diameter.

You can find other vacuum fittings with the larger nipple in the center and a few smaller ones coming off the side. That way you can get the proper diameter and volume of vacuum to the booster and also connect any of the other accessories back up to the smaller ones.

You can also get the smaller diameter manifold vacuum ports from the bottom base plate in the carb. Make sure that it is on the base plate for intake vacuum.

The one above the base plate is ported vacuum that is used for the vacuum advance for the distributor...
