Inline Fuel Filter - #12 Billet - Black

The SYSTEM ONE Inline Fuel Filter – #12 Billet in Black (SKU SYS202-202412B) is a high-flow fuel filtration solution designed for high-performance fuel systems that demand both reliability and superior flow capacity. This inline fuel filter features a stainless steel 35-micron element housed in a durable black anodized aluminum body, delivering contamination control without sacrificing the fuel delivery rates required by turbocharged, supercharged, and naturally aspirated performance engines.

The 35-micron filtration rating represents an ideal balance in fuel system protection. This micron rating captures suspended particles and debris that can damage fuel injectors and pump components while maintaining low restriction for engines requiring substantial fuel flow at peak demand. Dual 12 AN male ports provide secure, leak-free connections to compatible fuel lines and components, ensuring compatibility with custom fuel system builds and aftermarket fuel management setups. The compact billet construction—measuring 2.25 x 2.25 x 10.75 inches and weighing just 0.9 lbs—facilitates installation in tight engine bay spaces without requiring extensive rework.

This filter suits builders and owners of performance fuel systems, motorsports applications, custom marine powerplants, and fuel-injected engine conversions where factory filtration is inadequate or incompatible. The stainless element resists corrosion and maintains filtration integrity across extended service intervals. Black anodized aluminum construction provides durability and heat dissipation in underhood environments while maintaining a finished appearance in visible installations.

Fuel filtration quality directly affects engine longevity and performance consistency. Undersized or low-efficiency filters compromise injector spray patterns and fuel pump reliability. The SYSTEM ONE #12 Billet delivers professional-grade filtration for serious performance builds where fuel system integrity cannot be compromised.
