Nozzle Jet .073 Brass

The Nozzle Jet .073 Brass by ENDERLE is a precision fuel system component engineered for high-performance carbureted engines, particularly in racing and custom automotive applications. This small but critical brass jet controls fuel atomization and metering through your carburetor's idle and transition circuits. Whether you're fine-tuning a street machine, competition drag car, or vintage hot rod, proper jet sizing is essential to dial in the ideal air-fuel ratio and eliminate flat spots or hesitation during acceleration.

Manufactured from brass for durability and thermal stability, the .073 orifice diameter is a mid-range size suited to mild to moderate engine builds and fuel pump pressure combinations. ENDERLE's precision machining ensures consistent bore tolerances, allowing fuel to flow at the exact rate your engine demands. The compact 0.5 x 0.5 x 1-inch profile and minimal 0.1 lb weight make installation straightforward, yet this component's influence on engine response and driveability is disproportionately significant. Brass construction resists corrosion and maintains dimensional integrity across repeated heat cycles, critical for reliability in both street and track environments.

Carburetor builders, engine tuners, and enthusiasts restoring or modifying classic muscle cars and performance vehicles will find the Nozzle Jet .073 Brass indispensable when optimizing fuel delivery. Installation requires removal of your carburetor's fuel bowl or nozzle body—a straightforward task for anyone with basic mechanical skills. Keep multiple sizes on hand during tuning sessions to experiment and achieve peak idle quality, transition response, and cruising efficiency. This ENDERLE component meets OEM specifications and is compatible with most four-barrel carburetors and many two-barrel designs; verify your carburetor's nozzle bore diameter before ordering to ensure correct fit.
