Reusable Hose End Black Straight -4

The Reusable Hose End Black Straight -4 from ALLSTAR PERFORMANCE is an essential hydraulic line component for fuel, oil, coolant, and brake system applications in custom and high-performance vehicles. Built for mechanics and enthusiasts who demand reliability in their fuel injection systems, engine modifications, and turbo setups, this straight fitting eliminates the frustration of permanent crimped hose connections that cannot be reused or repositioned during engine builds or system upgrades. When you're fabricating custom fuel rails, rerouting brake lines, or building a modified engine compartment, the ability to disconnect and reconfigure your hydraulic lines without waste becomes invaluable.

This -4 AN (Anderson) sized hose end features a straight configuration that connects flush to your hose without any bend, making it ideal for tight engine bay layouts where space is at a premium. The black anodized aluminum construction resists corrosion in harsh underhood environments while maintaining a clean, professional appearance in show-quality builds. The reusable design means you can install, inspect, and adjust your fuel or fluid lines multiple times without degradation—critical when tuning fuel delivery systems or diagnosing pressure issues during dyno testing. The straight geometry provides direct flow path efficiency without turbulence, an important consideration for precision fuel systems where consistent pressure is necessary for proper engine management.

Street rodders, EFI retrofit specialists, and performance builders rely on these fittings for custom fuel system assemblies where OEM hose configurations don't accommodate modified engine positions or turbocharger placements. Whether you're installing a carbureted engine in a modern chassis, upgrading to port fuel injection, or recirculating coolant through auxiliary cooling systems, the -4 AN size accommodates moderate to high-flow applications without the pressure drop of undersized lines. Installation requires a standard hose with -4 AN internal bore; simply slide the hose onto the male end and tighten the collar—no special tools or crimping equipment needed, making field adjustments and rebuilds straightforward for both professional shops and home garage mechanics.
