Pro Mod 4-Vane Vacuum Pump w/Brkts. & Hdwr

The MOROSO Pro Mod 4-Vane Vacuum Pump with Brackets and Hardware is a mechanical vacuum pump engineered specifically for pro mod–style engine builds that require dependable vacuum generation for brake booster systems and accessory functions. Built from anodized aluminum construction, this compact 4-vane pump delivers consistent vacuum output while resisting corrosion in high-heat engine compartments. The pump is supplied complete with all necessary brackets and mounting hardware, eliminating the need for sourcing additional components.

The 4-vane design provides smooth, pulse-free vacuum generation across the RPM range typical of modified engines, translating to reliable brake booster performance and consistent operation of vacuum-dependent systems. The anodized aluminum construction balances weight savings with durability—critical considerations in performance applications where engine bay real estate and component weight both matter. At 7.35 lbs, the pump adds minimal mass while maintaining the structural integrity needed for sustained high-RPM operation. The compact footprint (7.8 x 7.3 x 8.1 inches) allows installation in tight modern engine compartments without requiring extensive custom fabrication.

This pump targets builders of pro mod engines, bracket racers, and street performance applications where OEM vacuum pump packaging conflicts with forced induction or custom intake manifold designs. It serves as a direct solution for applications that have eliminated the factory serpentine-driven pump or where engine displacement and aspiration changes require a standalone vacuum source. The included brackets simplify installation, reducing build time and ensuring the pump integrates cleanly into the final engine package.

MOROSO has established credibility in the performance engine community through precision component design and materials selection. For pro mod builders and serious enthusiasts evaluating standalone vacuum pump options, the Pro Mod 4-Vane delivers the engineering detail and complete mounting solution expected in this competitive segment. Verify belt drive compatibility and vacuum line sizing against your specific engine platform before installation.
