10AN Premium 235 Series E85 Nylon Hose 15ft BLK

The 10AN Premium 235 Series E85 Nylon Hose in black, 15 feet long, is engineered for high-performance fuel system applications where reliability and chemical resistance are non-negotiable. Built by REDHORSE PERFORMANCE, this hose assembly serves ethanol-blended (E85) fuel systems commonly found in modern turbo builds, naturally aspirated performance engines, and flex-fuel vehicles running aggressive tune maps. Whether you're upgrading from OEM rubber lines or fabricating a complete fuel delivery system, this 10AN hose delivers the durability and compatibility required for sustained power output without leaks or degradation.

The 235 Series construction features premium nylon inner tubing specifically formulated to resist E85's aggressive solvency—ethanol corrodes standard rubber and inferior synthetic blends over time, causing fuel weeping and system failure under boost or load. REDHORSE's nylon formulation maintains structural integrity across temperature swings and ethanol saturation, while the outer cover provides abrasion and UV protection in engine bay environments. The 10AN fitting size (5/8-inch diameter) offers substantial flow capacity suitable for fuel injection systems ranging from 600 to 1000+ horsepower applications, with a 15-foot length providing routing flexibility through custom frame rails, firewall passages, or remote fuel cell installations without mid-line couplers that introduce leak points.

Mechanics and engine builders favor this hose for turbocharged LS swaps, Coyote crate engine installs, and standalone fuel systems where OEM routing is impossible. The black finish resists heat discoloration in high-temperature underhood zones, and the 15-foot length eliminates the need for adapters or shorter segments that complicate leak diagnosis. Installation pairs seamlessly with 10AN male/female fittings, fuel pressure regulators rated for E85, and quality fuel pumps—verify your system's AN size and fuel pump outlet diameter before ordering. This hose is not suitable for nitromethane or other exotic fuels; E85 and gasoline blends only.
