    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.
