Questions: Will this take the place of part of the vac system and does it mount in the fuel pump?

It really doesn't involve the vacuum per se. If your engine needs additional air flow for the fuel/air mixture - it allows it in but not out. Ensures a proper fuel delivery system. It screws into your original pump.
