-8AN 150ft PTFE Stainles Steel Braided Flex Hose

The -8AN 150ft PTFE Stainless Steel Braided Flex Hose is a critical component for high-performance fuel, oil, and coolant systems in custom and modified vehicles. Purpose-built for serious mechanics and enthusiasts running turbocharged engines, nitrous systems, and complex fuel management setups, this hose assembly eliminates the guesswork of routing fluid lines through tight engine bays. At 150 feet, this roll provides enough length to handle multiple system runs or allows custom-length segments to be fabricated for specific vehicle architectures without mid-line connections that compromise pressure integrity.

The -8AN sizing—representing a nominal 1/2-inch inner diameter—is the industry standard for fuel delivery in turbocharged applications and forced-induction engine builds. PTFE (polytetrafluoroethylene) inner core resists fuel degradation, maintains flexibility across temperature extremes, and never swells or becomes brittle like rubber compounds. The stainless steel braided exterior provides abrasion resistance, pressure containment up to 3000 PSI, and radiant heat protection in engine compartments where underhood temperatures exceed 200°F. This construction is rated for ethanol-blend fuels, methanol, and synthetic oils—essential for tuned vehicles running pump gas or alternative fuels without risk of hose failure or internal contamination.

Mechanics designing fuel systems for LS swaps, modern 5.0 Coyote builds, and turbo four-cylinder platforms will find this hose indispensable for pre-filter, post-filter, and carbureted applications where OEM rubber hose fails under boost or modified fuel pressure schedules. The 150-foot bulk roll reduces cost per foot versus pre-made assemblies and allows routing flexibility around custom engine bay layouts, transmission tunnel modifications, and rear-mounted fuel cell configurations. Pair with -8AN fittings and clamps rated for your system's maximum pressure to ensure safety and reliability at the track or on the street.
