Accelerator Discharge Nozzle - Hollow

The Accelerator Discharge Nozzle - Hollow by HOLLEY is a precision fuel system component engineered for carburetor optimization and engine performance tuning. Designed for high-performance and racing applications, this hollow discharge nozzle serves as a critical internal passage component that regulates fuel atomization and delivery during acceleration events. Carburetor enthusiasts and engine builders rely on discharge nozzles to fine-tune throttle response and fuel mixture consistency across varying engine speeds and load conditions.

Manufactured from durable steel, the Accelerator Discharge Nozzle - Hollow features a hollow bore design rated for 0.040-inch and larger nozzle applications, allowing precise control over fuel flow during the acceleration pump cycle. The hollow construction enables engineers to match fuel delivery characteristics to specific engine requirements, improving cold-start performance, transition response, and overall drivability. HOLLEY's reputation for fuel system precision ensures this component meets exacting tolerances necessary for consistent carburetor operation across temperature and altitude variations.

This nozzle is ideal for carburetor rebuilds, performance upgrades, and engine restoration projects where original equipment replacement or tuning optimization is required. Installation requires carburetor disassembly and proper bore sizing verification to ensure compatibility with your specific HOLLEY carburetor model. Engine builders and carburetor specialists commonly specify this component when addressing acceleration hesitation or fuel delivery inconsistencies in street, strip, and vintage racing applications.
