Billet HP Fuel Filter - 3/8NPT 100-Micron 175GPH

The Holley Billet HP Fuel Filter with 3/8 NPT ports and 100-micron stainless steel element delivers precision fuel delivery for high-performance applications demanding reliable filtration at elevated flow rates. Built from billet aluminum with black and clear anodized finish, this in-line fuel filter combines durability with the corrosion resistance required in demanding engine environments, whether in performance street applications, marine duty, or motorsport contexts where fuel purity directly impacts injector longevity and engine reliability.

The 100-micron stainless element provides intermediate filtration that removes suspended particulates without restricting flow—critical at 175 GPH capacity where pressure drop becomes a tuning variable. The 3/8 inch NPT female inlet and outlet ports accommodate standard fuel line sizing across most carburetor and fuel injection setups. Billet aluminum construction resists vibration-induced fatigue better than cast housings, and the clear sight bowl allows quick visual verification of element condition without disassembly. The black and clear anodized finish protects against corrosion from ethanol-blended fuels and condensation accumulation in seasonal storage.

This filter suits builders and enthusiasts optimizing carburetor fuel delivery, manifold injection conversions, or replacement of factory filtration on performance builds where flow capacity and element serviceability matter. The compact 5.35 x 2.15 x 7.65 inch footprint fits engine bays with space constraints while maintaining sufficient surface area for extended service intervals between changes. Operators running ethanol or E85 fuel benefit from the stainless element's resistance to alcohol-induced degradation that affects traditional paper media.
