#12 XR-31 Nylon Braided Hose 20ft

The #12 XR-31 Nylon Braided Hose 20ft is a professional-grade fuel and fluid line designed for high-performance automotive applications, from street-built engines to full competition setups. Whether you're tuning a carbureted classic, upgrading a fuel-injected platform, or fabricating a custom hot rod, this hose delivers the reliability and durability that serious mechanics and enthusiasts demand. The 20-foot length provides flexibility for complex engine bay layouts, custom fuel cells, and remote-mounted fuel systems without requiring multiple splice points or compromising flow integrity.

Constructed with nylon braiding and engineered to XRP-XTREME RACING PRODUCTS standards, the #12 hose features a reinforced outer layer that resists abrasion, oil degradation, and UV exposure—critical factors in underhood environments where hoses run alongside headers, intake manifolds, and hot engine blocks. The braided design provides superior kink resistance compared to rubber hose alone, ensuring consistent fuel delivery under pressure cycling and vibration loads common in high-RPM and forced-induction engines. The -12 AN designation indicates a 3/4-inch outer diameter, accommodating substantial fuel flow rates while maintaining compact routing through tight engine compartments.

This hose excels in fuel system upgrades, EFI conversions, nitrous oxide systems, and carburetor fuel line replacements where stock rubber hoses fail or restrict flow. Mechanics and fabricators also use extended lengths for custom fuel cell installations, cross-frame fuel routing, and applications requiring feed and return lines separated by distance. Pair the #12 XR-31 with compatible AN fittings and fuel system components for a professional-grade installation that handles both daily driving and track use with confidence.
