Vacuum for PVC valve and Master Power Booster Brake options.

Post #1 by ray6966 » Sun Mar 29, 2015 11:26 pm

how is everybody getting vacuum for the PVC valve and the Master Power Booster Brake (if any)? I know the intake manifold has a port for vacuum. I need 18Hg for the Power Booster Brake, can I use the same port for the PVC valve?. Meaning, can I use a Y-fitting in order to supply vacuum to the PVC valve and the Master Power Booster Brake from the Aluminum Intake Manifold at the same time? anyone has this set up? The 2100 Autolite Carb (2V) has a nipple port that I'm going to use to supply vacuum to the DUI distributor in my setup. Other than that, I don't see any other choice than creating a new port on the intake manifold or perhaps drilling a hole in the 2V carburetor adapter plate. Thanks.

You could use the same port for both the Power Booster and PVC valve, my preference though would be to drill and tap the carb adapter for the PVC would be better to get the valves vacuum source just below the throttle plates. Good luck :nod:
