3/4 Aluminum Scalloped Tube - 36in.

The 3/4 Aluminum Scalloped Tube - 36in. from QUICKCAR RACING PRODUCTS is a precision-engineered fuel line or coolant conduit designed for serious race car builders and high-performance automotive fabricators. Built for durability and reliability in demanding engine compartments, this scalloped aluminum tube serves as a critical plumbing component in custom vehicle builds, fuel system upgrades, and race-spec cooling systems. Whether you're assembling a dedicated track car or retrofitting a street machine with competition-grade components, this tube delivers the structural integrity and corrosion resistance that separates amateur work from professional results.

Machined from aircraft-grade aluminum alloy, the 3/4 Aluminum Scalloped Tube features a 1.5 x 1.5 inch square cross-section with scalloped edges—a design choice that reduces weight while maintaining rigidity under pressure and vibration stress. The scalloped profile also improves airflow around the tube in tight engine bays, critical for thermal management in forced-induction or naturally aspirated builds where every degree of coolant temperature matters. At 2.3 pounds for the full 36-inch length, this component minimizes rotational mass and unsprung weight without sacrificing wall thickness or burst strength. Aluminum's superior thermal conductivity compared to steel makes it the preferred material for modern fuel delivery and coolant circuits in high-revving engines.

This tube is ideal for fabricators building custom intake manifolds, fuel rails, bypass lines, or heater hose assemblies on street rods, drag cars, circuit racers, and engine swap projects. Its 36-inch length accommodates routing through standard engine compartments with room for bends and fittings, while the aluminum construction eliminates rust concerns in wet climates or long-term storage. Professional mechanics and weekend builders alike rely on QUICKCAR RACING PRODUCTS components for consistency and fitment; this tube pairs seamlessly with standard -8, -10, or -12 AN fittings and compression adapters commonly found in race-spec fuel systems. Proper deburring and cleaning before final assembly ensures optimal flow and prevents contamination in sensitive fuel injectors or cooling circuits.
