6AN 401 Series Push Lock Hose 20ft Blue

The 6AN 401 Series Push Lock Hose 20ft Blue by REDHORSE PERFORMANCE is the fuel system upgrade serious engine builders and performance mechanics rely on for high-flow applications. Whether you're running a forced induction build, carbureted stroker, or modern fuel-injected platform, this push lock hose handles fuel delivery with reliability and simplicity. The 20-foot length accommodates flexible routing from tank to carb or fuel rail, eliminating the rigid steel line constraints that plague factory fuel systems and aftermarket engine swaps.

Engineered with a 6AN nominal bore diameter, this hose delivers consistent flow rates required for engines producing elevated fuel demand without pressure drops or restriction. The 401 Series designation indicates REDHORSE PERFORMANCE's push lock fitting system—a field-proven crimped connection that eliminates the need for external hose clamps, reducing leak points and keeping your engine bay clean. The blue outer cover resists UV degradation and identifies your fuel system at a glance, while the inner core maintains integrity under sustained pressure cycling, vibration, and thermal stress typical of performance and competition environments.

Mechanics installing carb conversions, turbocharged setups, or fuel system relocations benefit most from the 6AN 401 Series Push Lock Hose because its pre-cut 20-foot length minimizes waste and the push lock design cuts installation time versus traditional crimped or clamped alternatives. Compatible with any 6AN push lock fitting—including fuel regulators, filters, distribution blocks, and fuel pump outlets—this hose integrates seamlessly into OEM or custom fuel system architectures. Ensure your fuel pump and regulator outlet match 6AN specifications for optimal fitment and pressure handling.
