This configuration also guarantees an incredibly quick vacuum recovery time, ensuring 17 in. to 23 in. Hg vacuum all the time. The pumps come in four standard configurations: Bare (no outer shell), Black, Chrome, or Gunmetal Gray ABS plastic outer shell. Each kit comes complete with 5 ft. of 3/8 in. supporting vacuum hose, proper wiring harnesses for an easy install, and vibration dampeners—all while maintaining a common mounting hole configuration.
