You are probably going to want to use one of those double action fuel pumps and/or a vacuum canister of some kind. When you've got your foot on the throttle, the advance sucks up most of the available vacuum, leaving little for your booster.

(The lead foot effect is very evident when it rains and you try to use your stock wipers.)

I'm not sure where the best place to tap would be. You could probably get a T connector and either do it at the hose for the wipers or the metal line for the advance. Those are the only two places that I can think of that would be convenient to the booster once it's installed.
