The 3AN Female to 4AN Male Expander Black by REDHORSE PERFORMANCE is a precision hose adapter designed for fuel and fluid system modifications where line sizing needs to step up safely. This adapter is ideal for those upgrading fuel delivery systems on modified engines, integrating aftermarket fuel pumps, or reconfiguring brake lines during suspension overhauls.
Manufactured from hardened aluminum with a black anodized finish, this expander fitting ensures a leak-free transition between 3AN and 4AN port sizes. Its concentric design maintains a consistent bore diameter across the transition, minimizing turbulence and pressure drop that can affect system performance.
Mechanics and fabricators rely on this adapter for various applications, including fuel system turnovers, EFI retrofits on carbureted platforms, and custom fuel cell installations. The female 3AN connection is compatible with standard hose ends, while the male 4AN outlet fits larger ports, making it critical for high-volume brake conversions and dual-pump fuel systems.
