HELIX High-Pressure Fuel Line - Green - 5/16" - 10' 516-0206

If you're running fuel system pressures at or above 100 PSI, OEM fuel lines simply won't cut it. The HELIX High-Pressure Fuel Line is engineered to handle demanding fuel delivery systems without degradation, kinking, or leaks—critical for forced induction setups, custom fuel injection tuning, and high-flow applications. Built with 85-durometer polyurethane and reinforced with a nylon inner band, this line delivers the reliability your engine demands.

Whether you're assembling a street performance build or fine-tuning a race fuel system, this U.S.A.-made component resists abrasion, chemicals, and temperature extremes that destroy lesser tubing. At 10 feet, you have enough length to route cleanly through engine bays while maintaining consistent pressure delivery.
