HELIX Fuel Line - Transparent Purple - 5/16" x 3' 516-7165

A fuel line is only as good as its ability to withstand heat, pressure, and chemical degradation—and this HELIX line delivers on all fronts. Whether you're running a carbureted setup, EFI system, or fuel cell, you need tubing that won't crack, harden, or fail under demanding conditions. This transparent purple hose gives you visibility to monitor fuel flow while maintaining the durability required for track use or high-performance street applications.

Built for reliability across extreme temperature swings and resistant to the corrosive effects of modern fuel blends, this 3-foot section is ready for custom routing in tight engine bays. Pair it with quality clamps (which we recommend regardless of system type) and you've got a fuel delivery component that won't let you down.
