6AN Fuel Filter Black

The REDHORSE PERFORMANCE 6AN Fuel Filter Black is a precision in-line fuel filtration component engineered for modified vehicles, turbocharged engines, and high-flow fuel systems where factory filtering falls short. Designed for automotive enthusiasts and performance builders who demand reliable fuel delivery under demanding conditions, this 4651 series filter addresses the critical need for clean fuel supply to fuel injectors, carburetors, and fuel injection systems. Whether upgrading a naturally aspirated engine or managing the increased fuel volume of a forced-induction setup, this inline filter provides the filtration backbone your fuel system requires.

Built with a stainless steel element rated at 40 microns, the 6AN Fuel Filter delivers effective particle separation without excessive restriction—a critical balance in modern fuel systems. The aluminum body with black anodized finish resists corrosion while maintaining a clean aesthetic in engine bays, while dual 6 AN male inlet and outlet ports ensure compatibility with braided stainless steel fuel lines and hose fittings common in custom fuel systems. The 40-micron filtration level captures contaminants small enough to damage fuel injectors while permitting adequate flow volume for both stock and modified fuel pumps.

Performance-focused builders benefit most from this filter when integrating aftermarket fuel systems, upgrading fuel pressure regulators, or installing higher-flow fuel injectors that are intolerant of contamination. Installation fits seamlessly in engine bay fuel line runs between the fuel tank and fuel rail, whether on carbureted classics or modern EFI platforms. The compact 2.9 x 2.6 x 8.9 inch dimensions make routing straightforward on most chassis, while the stainless element design tolerates extended service intervals compared to traditional paper media—particularly valuable when using ethanol-blended fuels or sourcing fuel from varied pump stations.
