#4 Blk Nylon Race Hose 6ft

The FRAGOLA #4 Black Nylon Race Hose 6ft is a lightweight, high-pressure fuel and fluid transfer line engineered for performance-oriented vehicles and engine builds. This hose is designed for racers, engine builders, and serious enthusiasts who demand reliability under extreme conditions. Whether you're running a turbocharged street car, a dedicated track machine, or a custom fuel system, this reinforced nylon construction delivers consistent flow and durability in demanding applications.

Constructed from reinforced nylon material, the FRAGOLA #4 hose features a robust design that resists kinking, abrasion, and fuel degradation even under sustained high pressure. The size designation (#4) refers to a dash-4 SAE fitting standard, enabling compatibility with industry-standard fuel system components and fittings found in modern race fuel systems. Nylon construction offers weight savings over braided stainless alternatives—critical for competitive motorsports applications—while maintaining excellent burst strength and chemical resistance to gasoline, nitromethane, and methanol-based fuels commonly used in racing.

This 6-foot section is ideal for fuel rail-to-fuel cell plumbing, carburetor fuel supply lines, or modular fuel system routing in street rods, circle track vehicles, and drag racing platforms. Installation is straightforward with standard dash-4 AN-style adapters and fittings; ensure proper hose clamp positioning and route away from exhaust headers to prevent heat damage. The FRAGOLA #4 hose is an essential component for anyone looking to enhance the performance and reliability of their fuel system.
