8AN Fuel Filter- Blue

The 8AN Fuel Filter – Blue from REDHORSE PERFORMANCE is a purpose-built inline fuel filtration system engineered for high-flow automotive applications where reliability and clean fuel delivery are non-negotiable. This compact yet robust filter serves serious mechanics and performance enthusiasts who demand consistent fuel quality in turbocharged, supercharged, or heavily modified engine builds. Whether you're upgrading a street performance car, race vehicle, or engine swap project, this stainless steel element design eliminates the guesswork and potential fuel contamination that can compromise fuel injector longevity and overall engine performance.

The 8AN Fuel Filter features a 100-micron stainless steel element that traps particulate, rust, and debris while maintaining high flow rates critical for fuel-injected and carbureted systems alike. Its aluminum construction with blue anodized finish resists corrosion and provides visual durability—essential when mounted in engine bays subject to heat cycling and moisture exposure. The 8 AN male inlet and outlet ports deliver seamless integration into custom fuel systems using standard -8 braided hose or hard-line configurations, eliminating the need for adapter fittings and reducing potential leak points. The compact 3.8 x 1.55 x 5.25-inch footprint makes it ideal for tight underhood installations where space is limited but performance cannot be compromised.

Mechanics and fabricators consistently choose the 4151 Series for engine swaps, fuel system rebuilds, and boost upgrades where OEM fuel filters fall short of flow demands. The stainless element's 100-micron rating strikes the ideal balance between protecting fuel injectors and avoiding excessive backpressure that can stress fuel pumps or cause lean-out conditions. Installation is straightforward—position the filter in-line between your fuel pump and fuel rail, secure the AN fittings hand-tight, and verify flow direction via the integral inlet/outlet marking. This filter works with carbureted engines, port fuel injection, and direct injection setups, making it a versatile choice for any serious automotive project.
