6AN 303 Series SS PTFE Hose 10ft SS

The 6AN 303 Series SS PTFE Hose 10ft SS from REDHORSE PERFORMANCE represents a critical upgrade for any serious automotive enthusiast tackling fuel system modifications, turbo plumbing, or high-performance cooling lines. This 10-foot stainless steel PTFE hose assembly is engineered for vehicles requiring reliable, corrosion-resistant fuel and fluid transfer in extreme under-hood environments. Whether you're building a turbocharged street car, fuel-injected classic, or competition vehicle, this hose accommodates the demanding pressures and temperatures of modern performance engines without compromise.

Built with a 6AN port size, this hose features a 303-series stainless steel outer braid combined with a PTFE (polytetrafluoroethylene) inner core, delivering superior chemical resistance and temperature stability across the full operating range of fuel systems and coolant circuits. The PTFE core eliminates permeation issues common in rubber hoses, ensuring no fuel vapor loss over extended service life. Stainless braid construction resists corrosion from salt spray, road chemicals, and engine bay moisture while providing mechanical protection against abrasion and impact. The 10-foot length offers flexibility for complex routing in engine bays with custom layouts, turbo manifolds, or relocated fuel cells.

This hose is ideal for fuel system builders, turbo installers, and mechanics upgrading OEM rubber lines on fuel-injected engines. The 6AN fitting size is standard for high-flow fuel systems, carbureted fuel supply lines, and boosted engine coolant bypass circuits. Installation requires compatible AN-style fittings at both ends; verify your existing or planned fittings match the 6AN specification before ordering. REDHORSE PERFORMANCE hose assemblies are recognized across the industry for consistent quality and reliable pressure ratings, making this 10-foot section a trusted choice for street, strip, and track applications.
