The 6AN 303 Series SS PTFE Hose 6ft SS from REDHORSE PERFORMANCE is a premium braided stainless steel fuel line designed for high-performance automotive and motorsport applications where reliability and corrosion resistance are non-negotiable. This hose assembly serves fuel systems, coolant lines, and other critical fluid transfer applications in race cars, hot rods, and modified vehicles where factory rubber hoses cannot withstand extreme temperatures, pressure spikes, or aggressive chemical exposure. Its compact 6-foot length makes it ideal for custom engine bay layouts and point-to-point fuel line routing.
This hose features a stainless steel braided outer jacket combined with a PTFE (polytetrafluoroethylene) inner core, delivering superior heat dissipation and chemical inertness compared to conventional rubber or nylon hoses. The 6 AN (5/8-inch) bore size accommodates moderate to high fuel flow rates without excessive pressure drop, while the stainless steel braiding protects against abrasion, UV degradation, and mechanical damage in engine compartments. PTFE inner tubing resists fuel permeation, maintains flexibility across a wide temperature range, and eliminates the swelling or degradation issues common with rubber hoses exposed to modern ethanol-blended fuels and high-octane racing fuels.
Buyers seeking the 6AN 303 Series SS PTFE Hose 6ft SS for sale typically include engine builders, fuel system integrators, and performance enthusiasts upgrading or rebuilding custom fuel systems. This hose pairs seamlessly with AN fittings and -6 fuel line standards, making it a direct replacement or upgrade for carbureted engines, EFI conversions, and turbo fuel systems operating under elevated pressure. Installation requires standard AN hose routing practices—avoid sharp bends, secure with P-clamps every 12–18 inches, and keep away from exhaust manifolds. The natural stainless finish resists corrosion in engine bays exposed to salt air, humidity, or washdowns, ensuring years of dependable service.
