#12 XR-31 Nylon Braided Hose 3ft

The #12 XR-31 Nylon Braided Hose 3ft from XRP-XTREME RACING PROD. is engineered for high-performance fuel, oil, and coolant delivery systems in modified and race vehicles. Built to withstand the demands of turbocharged engines, nitrous systems, and aggressive fuel mapping, this hose assembly serves as a critical component in any serious automotive build. Whether you're upgrading fuel lines on a street performance car or plumbing a full custom engine bay, this hose delivers the reliability and durability required when stock plumbing won't cut it.

Constructed with tightly woven nylon braiding over a reinforced inner core, the #12 XR-31 hose resists abrasion, heat cycling, and vibration—three primary failure points in underhood environments. The braided exterior protects against chafing against engine bay edges and sharp fasteners while providing superior pressure containment compared to bare rubber lines. The #12 sizing indicates a nominal inner diameter suitable for mid-flow applications, making it ideal for fuel systems on engines producing moderate to high horsepower without excessive line restriction. At 3 feet in length, this hose cut allows builders flexibility in routing through tight engine compartments or along frame rails.

Mechanics and engine builders favor XRP-XTREME RACING PROD. hose assemblies for their proven track record in competition and street applications. Installation requires proper fittings at each end—confirm your specific AN or NPT connection type before ordering. This hose works across fuel, coolant, and oil circulation roles, though always verify fluid compatibility and temperature ratings against your system specifications. Weighing just over 1 pound, the compact 3-foot section minimizes excess hose weight while maintaining clean routing through modern engine bay layouts.
