Power Brake Booster Vacuum Pump

The Power Brake Booster Vacuum Pump (EVP21) by RIGHT STUFF DETAILING is an essential auxiliary vacuum source for vehicles with modified or custom brake systems. Whether you're running a carbureted engine swap, building a street rod, or installing an aftermarket brake booster on a classic car, maintaining consistent vacuum supply is critical to reliable brake operation. This pump solves a common problem faced by enthusiasts: stock engine configurations often provide insufficient vacuum for high-performance applications, vacuum-assisted steering, or when relocating brake components away from the intake manifold.

This vacuum pump operates independently of engine intake vacuum, generating consistent pressure on demand rather than relying on manifold depression. The compact design measures 9.15 x 9 x 9.15 inches and weighs just 7.24 lbs, making it ideal for tight engine bay installations common in custom builds and restorations. The self-contained operation ensures brake booster function remains unaffected by throttle transitions, idle quality, or fuel mixture tuning—critical for vehicles where engine modifications have compromised traditional vacuum availability. Its robust construction handles the continuous duty cycle typical of street-driven custom vehicles.

Street rodders, classic car restorers, and performance engine builders rely on this pump when converting to disc brakes, upgrading brake systems, or running non-OEM engine combinations. Installation involves securing the pump to the frame or engine block and connecting vacuum lines to your brake booster and reserve tank. Mechanics frequently specify this pump for crate engine swaps, turbo builds where intake vacuum is compromised, and any application where brake feel and responsiveness depend on stable vacuum pressure. The EVP21 has become an industry standard for these applications.
