3/8 Aluminum Scalloped Tube - 28.0in.

The 3/8 Aluminum Scalloped Tube by QUICKCAR Racing Products is a precision-engineered component designed for custom vehicle builds, fuel system routing, and performance engine modifications. Built for automotive enthusiasts and professional fabricators, this 28-inch tube serves as a critical conduit in high-performance fuel delivery systems, transmission coolers, and custom plumbing applications where reliability and durability matter. The scalloped design reduces weight while maintaining structural integrity, making it ideal for both street and competition vehicles where every ounce counts.

Fabricated from lightweight aluminum, this tube features a 3/8-inch nominal diameter with internal scalloping that reduces overall mass to just 0.58 pounds without compromising flow characteristics or burst strength. The scalloped exterior profile enhances aesthetics in visible engine bay installations while the smooth interior walls minimize turbulence and pressure drop—critical factors in fuel systems operating at elevated pressures. At 28 inches in length, this tube spans typical engine compartment distances, eliminating the need for multiple connectors that introduce failure points and restrict flow rates in high-demand racing applications.

Mechanics and fabricators building turbo systems, supercharger installations, and custom fuel rails will appreciate the lightweight construction and clean appearance this tube delivers. Compatible with standard 3/8-inch barbed and compression fittings, it integrates seamlessly into existing fuel delivery, coolant, or pneumatic systems. The 28-inch length accommodates mid-engine, front-engine, and rear-mounted configurations, making it a versatile solution for everything from drag racing fuel systems to street rod restorations where form and function must align.
