Billet HP Fuel Filter - 3/8NPT 10-Micron 175GPH

The Holley Billet HP Fuel Filter with 3/8 NPT ports is a high-flow in-line fuel filter engineered for carbureted and fuel-injected engine systems demanding reliable contamination control without pressure drop penalties. With a 10-micron paper element and 175 GPH flow capacity, this filter combines precision aluminum construction with anodized durability to maintain fuel system integrity across a wide range of engine configurations and operating conditions.

The 10-micron filtration rating captures particulates and water contamination while the 175 GPH rating ensures adequate fuel delivery to high-performance carburetors and fuel-injection systems without starving the engine under sustained demand. The billet aluminum housing with black and clear anodized finish resists corrosion and provides visual fuel level monitoring through the transparent body. Female 3/8 NPT inlet and outlet ports accommodate standard fuel line adapters and allow straightforward integration into existing fuel systems. The paper element design offers effective dirt capacity while maintaining consistent flow characteristics throughout the filter's service life.

This filter is suited for builders and operators maintaining vintage hot rods, classic cars, custom trucks, and carbureted performance engines where fuel quality directly impacts carburetor tuning stability and engine reliability. It serves equally well in fuel-injected systems where contamination control prevents injector clogging and fuel pump wear. The compact, lightweight design (0.81 lbs) fits easily in engine bays with limited space, and the industry-standard NPT threaded connections eliminate custom fabrication requirements during installation.

The Holley Billet HP represents the brand's heritage in high-performance fuel system components. This filter addresses a fundamental requirement in engine tuning: consistent, clean fuel supply. By filtering to 10 microns while maintaining 175 GPH capacity, the unit balances protection against sediment and water ingress with the flow demands of modern and classic carburetors, making it a proven choice for serious engine builders and weekend enthusiasts alike.
