3in Aluminum Filter #6 x 3/8in Polished

The 3in Aluminum Filter #6 x 3/8in Polished is a competition-grade in-line fuel filter designed for serious enthusiasts who demand precision fuel delivery in high-performance engine builds. As a dedicated inline filter system, this Russell component protects fuel injection systems and carburetors from contamination while maintaining clean flow under demanding driving conditions. Whether you're running a street-strip build, drag racing platform, or turbocharged daily driver, this filter bridges the gap between stock reliability and race-proven performance.

Built from polished aluminum construction, the 3in Aluminum Filter features a 40-micron stainless steel element that captures fuel contaminants without restricting flow—critical for high-volume fuel systems and fuel injection setups where pressure consistency directly affects tune stability. The 6 AN male inlet and 3/8 inch NPT male outlet configuration provides flexible plumbing integration with both braided line systems and threaded port connections common in modified fuel systems. The compact 3in diameter design fits tight engine bays while the polished finish complements performance aesthetics and resists corrosion in harsh underhood environments. At 0.25 lbs, it adds negligible weight while delivering the filtering reliability race teams depend on.

This filter excels in fuel-injected engines where micron rating and pressure stability prevent injector clogging and fuel system component wear. Mechanics installing custom fuel systems, upgrading carbureted platforms to EFI, or building competition engines should specify this Russell unit for dependable mid-system filtration. The AN and NPT dual outlet design accommodates pressure gauges, regulators, and secondary fuel line branches—making it ideal for complex fuel systems where monitoring and control are essential. Installation requires standard hose clamps and adapters; verify ANP sizing against your existing fuel system layout before ordering to ensure seamless integration.
