i would like to add one to my car. the brakes are sometimes very hard to push, other times theres sufficient vacuum to assist. hvac is holding up on its own. how would i route the hose to do it? does it go from the manifold to the reservoir, then the booster?

 

Yep, that's about it. My C3 Vette came with a vacuum reservoir from the factory, there's a load of vacuum driven stuff on that car.
