5/16 Aluminum Scalloped Tube - 22in.

The 5/16 Aluminum Scalloped Tube - 22in. from QuickCar Racing Products is a lightweight fuel or coolant line component engineered for high-performance automotive builds where every ounce counts. Precision-machined from aluminum alloy, this 22-inch tube is purpose-built for custom engine bays, race cars, and modified street vehicles where rigid, corrosion-resistant tubing runs are essential. Whether routing fuel from a relocated tank, plumbing coolant bypass circuits, or managing custom intake manifold passages, this scalloped design delivers both form and function in a compact footprint.

The scalloped profile reduces weight compared to solid tubing while maintaining structural rigidity, a critical advantage in competition and performance applications where mass reduction directly impacts acceleration and fuel economy. At 5/16-inch outer diameter with a 22-inch straight length, this tube accommodates standard 5/16 hose barbs and fittings commonly used in fuel systems and cooling circuits on modified LS, small-block, and vintage engines. The aluminum construction resists oxidation and provides superior thermal conductivity, helping dissipate heat in high-flow cooling systems while remaining compatible with ethanol fuel blends and standard engine coolants.

This tube excels in custom engine bay layouts where space constraints demand compact routing and weight savings are non-negotiable—drag racing, road course cars, and turbocharged street builds benefit most from its lightweight aluminum construction. The 22-inch length provides flexible run routing between engine compartment boundaries, making it ideal for fuel return lines, coolant bypass tubes, and intercooler plumbing. Installation requires standard hose clamps or compression fittings at 5/16-inch barbed connections; ensure all fuel system work complies with local codes and use appropriate fuel-rated hose for compatibility with modern gasoline and alternative fuels.
