The car (most likely) parked in your driveway has some form of a factory vacuum pump. It functions via one of two ways: as a mechanical engine driven or electrically powered pump. It generates additional (supplemental) vacuum that is in addition to what the engine can produce. While new cars are designed with these as part of the integral workings, hot rodders need to take the needs this pump provides into consideration. We have a way for you to manage this dilemma: the Granatelli Motor Sports 12V Electric Vacuum Pump Kit.
