5/16 Aluminum Scalloped Tube - 6.5in

The 5/16 Aluminum Scalloped Tube – 6.5in from QUICKCAR RACING PRODUCTS is a precision-engineered fuel line and hydraulic tubing component built for high-performance automotive applications. Designed by and for racers and serious performance enthusiasts, this aluminum tube serves as a core building block in custom fuel systems, brake lines, and transmission cooler setups where weight savings and reliable flow characteristics are non-negotiable. Whether you're fabricating a custom drag car fuel cell system, upgrading a street machine's brake circuit, or designing a competition-grade engine bay, this scalloped tube delivers the lightweight construction and consistent bore geometry that separates amateur builds from championship-level work.

Manufactured from aerospace-grade aluminum alloy, the 5/16 Aluminum Scalloped Tube features a scalloped (grooved) exterior profile that reduces weight without sacrificing strength or flow capacity. The 5/16-inch diameter accommodates mid-range fuel delivery volumes common in small-block and LS-based engine swaps, while the 6.5-inch length provides a versatile segment for custom plumbing runs between fuel cells, carburetors, regulators, and hard-line connections. The scallop design enhances visual appeal in engine bays visible through carbon fiber or polycarbonate covers, while the lightweight construction contributes meaningfully to overall vehicle weight reduction—critical in bracket racing and autocross competition where every tenth counts. At just 0.13 pounds, this segment adds minimal mass while maintaining structural integrity under pressure and vibration.

This tube is ideal for fabricators, engine builders, and racers who demand components that match the precision of their builds. It pairs seamlessly with QUICKCAR Racing Products' full line of aluminum fittings, bulkhead connectors, and fuel system manifolds, allowing you to construct complete custom circuits without mixing materials or tolerances. Installation requires standard aluminum-compatible tools and techniques; tig welding is recommended for permanent junctions, while compression fittings and AN adapters work perfectly for modular configurations. Compatible with standard -6 AN hose and fitting sizes, this tube integrates effortlessly into street rods, circle-track cars, marine performance engines, and any application where aluminum fuel systems are preferred for corrosion resistance and weight optimization.
