50ft Roll Black Nylon Braided Flex Hose -12AN

The 50ft Roll Black Nylon Braided Flex Hose -12AN by Vibrant Performance is the professional-grade solution for fuel, oil, coolant, and transmission line runs in serious engine builds and modifications. Whether you're constructing a fuel system for a turbo upgrade, routing lines through a custom engine bay layout, or fabricating a complete fuel cell installation, this bulk roll eliminates the need to splice multiple shorter hose sections. Built for high-flow applications and designed to handle the demands of street and track performance vehicles, the -12AN sizing accommodates systems requiring robust fuel delivery without pressure loss across long runs.

Constructed with black nylon braided outer sleeve over a reinforced inner core, this hose resists abrasion, UV damage, and contact with underhood heat and solvents that degrade standard rubber tubing. The -12AN designation refers to the hose's 12/16-inch nominal diameter and working pressure rating suitable for fuel injection systems, EFI conversions, and pressurized coolant circuits operating up to typical performance system specs. The braided weave provides flexibility for routing around engine components, turbochargers, and intercoolers while maintaining structural integrity under vibration and thermal cycling—critical in modified engines where standard factory routing won't accommodate new hardware. The 50-foot roll format allows fabricators to cut custom lengths and minimize waste on single-hose applications or multi-line installations.

This roll is ideal for engine builders, performance shops, and enthusiasts upgrading fuel systems, installing auxiliary cooling loops, or converting carbureted engines to EFI. Mechanics working on LS swaps, turbo installations, and complete fuel cell builds benefit from bulk inventory to eliminate supply chain delays. The -12AN size integrates seamlessly with common AN fittings and manifold ports on modern fuel rails, headers, and aftermarket intake components. Installation requires standard AN crimpers and fittings (sold separately), and proper hose support clamps prevent chafing and vibration-induced fatigue. Always verify application-specific pressure ratings and fluid compatibility before final assembly.
