Aeroflow Billet Oil Pump Primer Tool Suits Chevrolet Small Block, Big Block & 90° V6

The first seconds an engine starts prior to building oil pressure are when damage can easily occur. Aeroflow Oil Pump Primer lets you spin the oil pump with a 3/8" drill and bring oil pressure prior to firing the engine. Aeroflow Oil Pump Primer offers a fantastic design. It includes a special billet aluminium sleeve that precisely positions the shaft and keeps it from wobbling.
