Racing vacuum pump for competition engines

The Moroso 22640 is a three-vane vacuum pump built with a billet aluminium housing for motorsport use. It creates negative crankcase pressure to improve ring seal and reduce windage losses on high-output engines. The unit mounts directly to the engine or chassis and uses 12AN inlet and outlet fittings for secure plumbing.

Replaces belt-driven pumps on dry-sump

This pump upgrades from conventional belt-driven vacuum pumps that cannot maintain consistent vacuum at high RPM. The three-vane design delivers steadier vacuum levels through the rev range, making the jump worthwhile for teams chasing maximum power on alcohol or race fuel. Builders who need a simpler single-vane unit or who run street-driven cars with emissions equipment should look elsewhere.

Questions about this item

What size fittings does the Moroso 22640 pump use for its 12AN inlet and outlet?

The pump has 12AN inlet and outlet fittings, so you need matching 12AN hose ends or adapters for the vacuum lines.

What is the correct mounting orientation for the 3 vane billet aluminum housing?

Mount the pump with the housing level and the vane rotor turning in the direction shown on the body; reversing rotation will not build vacuum.
