LS Oil Pump Primer

The PROFORM LS Oil Pump Primer is a specialized pre-oiling tool designed for LS engine builders and performance enthusiasts who require proper lubrication before the first startup. This tool is essential for those assembling an LS block, rebuilding after a major refresh, or swapping in a stroker, as it helps prevent the risk of running the engine dry during critical startup moments.

The primer operates by mechanically rotating the LS oil pump, allowing fresh oil to circulate through the engine's galleries, bearings, and valve train components before ignition. This mimics normal pump operation without needing to rotate the engine, ensuring that lubrication is established throughout the system. Its compact design makes it easy to maneuver in tight engine bays, and its durable construction allows for repeated use across multiple builds.

LS engine builders, whether working on carbureted race motors, turbo street builds, or naturally aspirated performance platforms, will find this tool invaluable for maintaining engine health. PROFORM's engineering guarantees compatibility with LS pump drives, providing consistent pre-oiling regardless of ambient temperature or oil viscosity.
