#3 St. Hose End

The #3 St. Hose End by EARLS is a precision-engineered hose fitting designed for custom fuel, coolant, and hydraulic systems in modified vehicles and high-performance applications. As a mechanic, you'll recognize this as an essential component for building clean, leak-free line assemblies in engine bays where stock routing won't suffice. Whether you're upgrading fuel delivery on a carbureted build, installing aftermarket cooling loops, or plumbing a custom fuel injection setup, a quality straight hose end is crucial for reliability and safety.

EARLS hose ends are manufactured from aerospace-grade aluminum alloy, ensuring consistent sealing and durability under pressure cycling and vibration—critical factors in engine compartments where thermal stress is constant. The straight configuration (#3 designation) provides a direct, low-restriction flow path without elbows or bends, reducing turbulence and pressure loss in fuel and coolant circuits. This lightweight design adds negligible mass to your system, making it ideal for performance applications.

This hose end excels in street rods, restomod builds, fuel-injected conversions, and any custom application where OEM hose routing isn't feasible. Installation is straightforward, allowing for compatibility with standard automotive hose sizes and acceptance of both crimped and reusable hose assemblies. This flexibility makes it a valuable addition to any custom engine build.
