Engine Primer Oil Filter Mount 12an Chevy L to R

The Engine Primer Oil Filter Mount 12AN Chevy L to R from Peterson Fluid is a precision-engineered oil filter adapter designed for custom engine builds, high-performance modifications, and street/race vehicle setups where remote oil filtration or priming pump integration is critical. This aluminum-constructed mount serves as the backbone of a pre-oiling system, allowing builders to pressurize the engine's oil galleries before startup—a practice that reduces bearing wear during initial engine rotation and protects newly rebuilt or modified powerplants. Whether you're finishing a Chevy small-block rebuild or integrating a primer pump into your LS platform, this adapter bridges the gap between your lubrication system and traditional filter housing.

The Engine Primer Oil Filter Mount 12AN Chevy L to R features dual 12 AN (AN12) male ports positioned for left-to-right (L to R) flow, accommodating standard -12 braided hoses or hard-line AN fittings commonly used in performance applications. The center-threaded design accepts a 13/16-16 inch thread pattern, compatible with most spin-on filter adapters and remote mounting configurations. Its natural aluminum finish resists corrosion while remaining lightweight at 2.55 pounds, and the compact 6.3 x 4.7 x 6.4 inch footprint allows flexible engine bay installation. The direct-port design eliminates flow restrictions, ensuring consistent oil delivery during priming cycles and normal circulation—essential when working with tight power budgets or turbocharged engines where oil pressure response time matters.

This mount suits engine builders, performance shops, and weekend enthusiasts upgrading Chevrolet small-block, LS, and compatible platforms where factory oil distribution is modified or supplemented. Installation pairs naturally with primer pump systems, remote filter canisters, and auxiliary cooling loops—setups common in circle-track racing, street rods, and custom engine swaps. The universal mounting footprint and standard 13/16-16 thread compatibility make it adaptable across multiple Chevy generations, though fitment verification for your specific application and exhaust/header layout is advised before purchase. Consult your engine manual or performance builder to confirm port orientation and hose routing that align with your intake manifold, block ports, and filter housing location.
