Moroso Chevrolet Big Block/Small Block/90 Degree V6 Oil Pump Primer w/Bushing

When you're building a Chevrolet engine, whether it's a big block, small block, or a 90-degree V6, priming the oil pump before the first start is a critical step. This tool from Moroso makes that job straightforward. It ensures that oil is circulated throughout the engine's lubrication system, coating all the moving parts with oil before the engine even turns over. This prevents dry starts, which can cause significant wear and tear on bearings, camshafts, and other vital components.

This primer is designed to fit directly into the distributor hole, allowing you to use a drill to spin the oil pump. It includes a bushing for a secure fit, ensuring it stays in place while you work. Using this tool helps you confirm oil pressure and that oil is reaching all the necessary passages, giving you peace of mind before you fire up your freshly built engine.
