Moroso Oil Pump Primer

The Moroso Oil Pump Primer line gives engine builders and racers a simple way to pre-lubricate an engine before its first start. Each tool, also called an oil pump priming tool or pre-lube tool, spins the oil pump driveshaft with a drill. This builds oil pressure and circulates oil through the passages and bearings before the engine fires. Pre-lubrication helps protect critical components during a fresh build, after an oil change, or after the engine has sat for a long time.

Key Features:

• Engages the oil pump drive so you can prime the system with a standard electric drill
• Helps build oil pressure and fill the oil galleries before startup
• Helps reduce dry-start wear on bearings, cam, lifters and other moving parts
• Durable steel construction built for repeated shop and garage use
• Available in several versions for different engine families and applications

Moroso has been a respected name in racing and performance parts for decades. This line reflects that experience with practical, well-made tools for engine assembly and maintenance. Choose the variant that matches your engine's oil pump drive.
