Hemi Oil Pump Primer

The Hemi Oil Pump Primer by PROFORM is an essential tool for any serious engine builder or mechanic working with Chrysler Hemi platforms. Whether you're assembling a fresh long-block, performing a complete engine rebuild, or installing a crate motor, this primer ensures proper oil distribution to critical bearing surfaces before initial startup. Without adequate pre-lubrication, metal-to-metal contact during cold cranking can cause catastrophic bearing damage, making this tool indispensable for protecting your investment in high-performance or stock Hemi powerplants.

This Hemi oil pump primer is specifically engineered to match OEM oil pump specifications and flow characteristics of Hemi engines, allowing you to manually cycle pressurized oil through the entire system before engine rotation. The compact design—measuring 3.4 x 3.3 x 6.7 inches and weighing just 0.6 lbs—fits easily into tight engine compartments and storage toolboxes. By priming the oil galleries, filter, and main/rod bearing journals before cranking, you significantly reduce dry-start wear and ensure that critical engine components receive immediate lubrication when the engine first fires, which is especially critical in performance applications where bearing clearances are tighter and oil pressure demands are higher.

Professional engine builders, restoration specialists, and Hemi enthusiasts rely on this primer whenever constructing engines from the ground up or after extended storage periods. It's equally valuable for vintage muscle car restorations, modern crate engine installations, and performance upgrades where you cannot afford bearing failure due to oil starvation. The primer integrates seamlessly with stock and aftermarket oil pump assemblies, making it compatible with first and second-generation Hemi platforms as well as modern 5.7L and 6.2L Hemi variants. Always use this tool as part of your pre-startup protocol—the minimal investment pays for itself by preventing even a single bearing replacement.
