Description
The accelerator pump discharge nozzle is a critical component that directly affects throttle response and fuel delivery precision in Holley carburetors. A worn or damaged nozzle causes inconsistent fuel atomization, leading to hesitation during acceleration and poor drivability across the RPM range. This genuine Holley replacement pair ensures crisp throttle response and reliable cold-start performance by delivering fuel at the exact flow rate your carburetor was engineered to use.
