Vacuum Pump Rebuild Kit - Enhanced Design

The MOROSO Vacuum Pump Rebuild Kit – Enhanced Design (Part #97181) is essential maintenance for any serious performance or street engine builder running mechanical vacuum pump systems. This precision rebuild kit restores pump functionality when internal wear, seal degradation, or performance loss occurs, making it ideal for hot rod builders, engine shop professionals, and weekend mechanics who demand reliability from their brake and ignition vacuum circuits. Whether you're refreshing a tired small-block or prepping a competition engine, this kit delivers OEM-quality restoration without the cost of a complete pump replacement.

The enhanced design incorporates precision-machined components and durable elastomer seals engineered to withstand sustained vacuum draw and thermal cycling common in high-performance applications. MOROSO's rebuild kit approach preserves your existing pump housing while replacing wear-critical internal elements—rotors, vanes, bearings, and gasket sets—that degrade under continuous operation. The compact 3.9 x 2.7 x 5.1 inch package contains all necessary components for complete reassembly, allowing you to perform the rebuild in your own shop and maintain tight tolerances that factory pumps demand for consistent brake assist and carburetor porting vacuum.

This kit is best suited for carbureted engines, classic muscle cars, street rods, and vintage race applications where mechanical pumps remain the standard. Technicians and builders benefit from the detailed rebuild process, which typically requires only basic hand tools and mechanical skill—no special equipment needed. Compatibility spans most bolt-on mechanical vacuum pumps from the 1960s onward; verify your pump's mounting flange and displacement specifications against the kit's design before ordering. At 0.7 lbs, the lightweight package ships easily and integrates seamlessly into any restoration or performance build timeline.
