5/16 Aluminum Scalloped Tube - 13.5in.

The 5/16 Aluminum Scalloped Tube – 13.5in from QUICKCAR RACING PRODUCTS is purpose-built for high-performance racing fuel systems and custom automotive plumbing applications. Designed for mechanics and enthusiasts tackling fuel line routing in race cars, street rods, and modified vehicles, this aluminum tube delivers the lightweight construction and precision fit demanded by serious engine builders. Whether you're assembling a fuel manifold, building a custom fuel rail, or routing feed lines through tight engine bays, this component addresses the need for durable, corrosion-resistant tubing that won't add unnecessary weight to your build.

Constructed from aluminum alloy, the 5/16 Aluminum Scalloped Tube features a scalloped interior design that optimizes flow characteristics while maintaining structural integrity under pressure cycling. The 5/16-inch diameter provides ideal sizing for fuel distribution in mid-range performance applications, balancing flow rate with fuel velocity to prevent cavitation and vapor lock issues common in carbureted and EFI race platforms. The 13.5-inch length accommodates typical fuel system distances from tank or pump to carburetor or fuel rail, and the lightweight 0.29 lbs construction keeps parasitic weight off your vehicle without compromising durability or reliability under continuous high-RPM operation.

Racers, engine builders, and fuel system specialists benefit most from this tube's proven QUICKCAR RACING PRODUCTS pedigree—a brand trusted across drag racing, circle track, and road racing communities. Installation works seamlessly with standard fuel line adapters and fittings sized for 5/16-inch tubing; the scalloped design reduces dead spots in fuel lines, improving response in carbureted fuel bowls and modern EFI systems alike. Compatibility spans bracket-mount configurations, frame rails, and firewall tunnels where compact routing and lightweight construction are non-negotiable. Perfect for fuel log assemblies, inline manifold sections, and custom fuel delivery plumbing on any engine platform.
