Description

The accelerator pump discharge nozzle is a critical component for consistent fuel atomization and precise throttle response in Holley carburetors. A worn or incorrect nozzle directly impacts cold-start performance, transition off-idle, and overall drivability—making this a high-priority maintenance item for any serious Holley setup. This OEM Holley unit delivers reliable, repeatable performance at a fraction of the cost of a full carburetor rebuild.
