Billet HP Fuel Filter - -8an 40-Micron 175GPH

The Billet HP Fuel Filter - -8an 40-Micron 175GPH from Holley is purpose-built for high-performance fuel systems where filtration quality and flow rate are non-negotiable. This in-line fuel filter is engineered for street and race applications where fuel purity directly impacts injector longevity, combustion efficiency, and engine reliability. Whether you're running a carbureted classic, a modern EFI swap, or a turbocharged build, this billet aluminum housing delivers the robust construction and precision filtration required to protect your fuel system from contamination.

The 40-micron stainless steel element captures particulates while maintaining a 175 GPH flow capacity, ensuring adequate fuel delivery even at high fuel pump volumes without creating unnecessary back-pressure. The billet aluminum construction with black and clear anodized finish resists corrosion and provides visual fuel level monitoring—critical for diagnosing fuel system issues in real time. Dual -8 AN female O-ring inlets and outlets offer secure, leak-free connections compatible with braided stainless or rubber fuel lines, while the compact 5.3 x 2.15 x 7.6-inch footprint allows flexible mounting in engine bays with space constraints.

Mechanics and performance builders rely on the Billet HP Fuel Filter for EFI conversions, fuel injection retrofits, and forced-induction builds where fuel system reliability cannot be compromised. The 175 GPH rating accommodates most aftermarket fuel pumps without restriction, while the 40-micron filtration standard protects fuel injectors from varnish buildup and debris that accelerates wear. Installation is straightforward with standard -8 AN adapters and O-ring fittings; simply position the filter in your fuel line between the pump and fuel rail, ensuring the inlet feeds from the tank and outlet routes to your fuel system.
