vacuum question

My holley carb only came with one small vacuum port. Do I need to tee off of it to run vacuum advance and charcoal canister and or the pcv? My intake manifold has one huge nipple coming out of it that was used for the brake booster. Do I even have to run a line to the canister to carb?

Re: vacuum question

I'm running a T for both the PCV and vapor canister without any problems.
