Hey pfcjal, it seems to me that you are referring to the charcoal cannister and not a vacuum can. If you had two lines attached to a vacuum canister plus the brakes, you would have no brakes, as in nada, zippo, zilsch!

My guess is that you are looking at a charcoal cannister and it's purpose is to take the fumes from the gas tank and send them into the carb. This is achieved via venturi vaccum and not manifold vacuum, sort of like a venting pipe off of a valve cover which goes to the air cleaner.

Manifld vacuum runs 11 to 17 inches whereas the air cleaner has no real measurable vacuum.
