My car only pulls 9Hg of vaccum and my power brakes arent working for shit. I was wondering if anyone has used a vacuum canister before? Does it work? Waste of $?

Also heres my other dilemma, the Edelbrock RPM manifold has only 1 port for PCV on the back of the manifold, only problem is you cant fit anything in the port with a holley carb:

What would be the best way to go around that? I was thinking of tapping the sidewall of the manifold going into the plenum and just putting a 3/8" fitting in there. to connect my PCV properly as thats also effecting my brakes.

Yes vacuum canisters work. Factory cars use them to keep the A/C doors under the dash working when the car is at WOT, but they use a smaller can. PCV in front, brakes in rear. I forget, doesnt the carb have a nipple in the rear for vacuum?

Yes I had to T mine because theres no place for manifold vaccum. So it's T'ed into the back port.
