20AN ProSeries 230 SS Core Hose 20ft Black

The 20AN ProSeries 230 SS Core Hose 20ft Black from REDHORSE PERFORMANCE is a professional-grade fuel and fluid line solution engineered for high-performance automotive builds, track cars, and custom engine swaps. If you're running a fuel system overhaul, upgrading to braided stainless steel hose, or building a competition vehicle, this hose delivers the durability and reliability that separates serious modifications from amateur installations. The 20-foot length provides flexibility for complex engine bay layouts without requiring mid-run fittings that introduce weak points.

The ProSeries 230 SS core utilizes stainless steel braiding over a reinforced synthetic inner tube, offering superior resistance to ethanol fuels, methanol blends, and modern pump gasoline while maintaining structural integrity under pressure cycling. The 20AN (AN20) fitting size accommodates mid-to-high flow fuel delivery systems typical in turbocharged, supercharged, and naturally aspirated performance engines operating above 400 horsepower. Stainless steel braiding minimizes heat transfer to fuel and provides abrasion protection in tight engine bays, while the black outer cover shields against UV degradation and road contamination—critical factors for long-term reliability in custom applications.

Performance shops and experienced DIY builders prefer AN-braided hose for fuel systems because it eliminates the failure modes associated with rubber lines—cracking, permeation, and pressure loss at high RPM. The 20-foot spool accommodates fuel cell installations, remote mounted fuel pumps, and complex custom frame routes without bulk ordering. Verify your fuel system fittings match AN20 (20 JIC or -20 equivalent) before ordering, and confirm hose routing clears moving engine components and exhaust systems to prevent contact wear or heat damage during operation.
