[Although this isn't my Buick, it's a very similar setup]
I have a pretty aggressive cam in my turbo Camaro. Most of the time, the manifold draws enough vacuum to give me power brakes, but most isn't good enough! So I installed an electric vacuum pump instead and blocked off the manifold line.
I'd like to T the two of them together, so that the pump has to work far less. Is there some way to assemble this so that
1. Boost isn't blown into the brake booster
2. The electric pump isn't forever trying to draw vacuum from the manifold.
