Compact 6AN Inlet/Outlet High Flow Fuel Filter

The Compact 6AN Inlet/Outlet High Flow Fuel Filter by REDHORSE PERFORMANCE is engineered for builders and enthusiasts who demand reliable fuel system protection without sacrificing flow capacity. Whether you're upgrading a carbureted hot rod, turbocharged street engine, or fuel-injected performance build, this filter bridges the gap between effective filtration and minimal restriction—critical when you've invested in quality fuel pumps and injectors. Its compact footprint makes it ideal for tight engine bays where space is at a premium, yet it maintains the flow characteristics needed for modern high-output fuel systems.

Built with high-flow internals, the 6AN inlet and outlet ports accommodate proper hose sizing for optimized fuel delivery at elevation and under load. The compact design doesn't compromise on element surface area; Redhorse engineered this unit to trap contaminants and moisture while maintaining the pressure stability your fuel system requires during acceleration and sustained boost. Its lightweight construction at just 0.2 lbs minimizes underhood clutter, and the small footprint (2.8 x 1.4 x 3.75 inches) permits flexible mounting options—whether inline on the fuel rail, mounted to the frame, or integrated into a custom fuel cell setup. The 6AN port sizing is industry standard for serious performance work, ensuring compatibility with quality braided hose and fitting ecosystems.

This filter excels in applications ranging from street machines and weekend track cars to dedicated drag builds where fuel consistency is non-negotiable. Install it upstream of your fuel rail for maximum protection of injectors and regulators, or position it at the tank output to protect the entire fuel system. Mechanics and tuners favor REDHORSE PERFORMANCE components for their durability and ease of integration; the 6AN connections accept standard AN fittings and -6 hose without adapters. Whether you're diagnosing fuel starvation issues on a modified engine or building a fuel system from scratch, this compact high-flow filter delivers the reliability and flow you need without compromise.
