Enhanced Racing Vacuum Pumps

Moroso has taken their popular 3-Vane Vacuum Pump and added tricks that they learned when designing the "Enhanced Design" 4-Vane Vacuum Pump and through continual development of their Vacuum Pump line. The end result is:

The "Enhanced Design" features allow the pump to pull more vacuum than the "original" style 3-Vane pump

Achieves greater vacuum sooner

3-Vane Design weighs less than "original" style pumps

Virtually maintenance free

Designed with maintenance-free precision sealed roller bearings

Includes -12AN Fittings

Does not include a mounting bracket, see Moroso mounting bracket options

Extra vacuum boosts power by: improving ring seal; preventing blow-by, intake charge contamination, and detonation; allowing the use of low-tension piston rings for less friction. These purpose-built vacuum pumps offer such power advantages in three designs to accommodate any engine combination and requirement. Use Moroso replacement pump fittings only.
