Summit Racing™ 12 V electric vacuum pumps utilize a rotary vane style pump with an enlarged diaphragm to ensure maximum suction while remaining nearly dead-quiet and vibration-free. Utilizing a Manifold Absolute Vacuum/Pressure (MAVP) sensor eliminates the need for old-school vacuum switches and relays. 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.

Built for racers and engine builders who craved the performance, Moroso racing vacuum pumps are manufactured from billet aluminum and feature a precision-machined shaft, rotor, and bearings that will withstand the rigors of racing. They work by producing high crankcase vacuum, which increases power by improving ring seal, preventing blowby, and detonation. Allowing the use of lower-tension piston rings for less friction. These positive pumps are much more consistent and effective than header-mounted evacuation systems.
