Description
A properly functioning accelerator pump discharge nozzle is critical for consistent fuel delivery and throttle response in Holley carburetors. Without precision tuning at this component level, you’ll experience flat spots off the line or erratic fuel atomization that compounds performance losses across the RPM range. The Holley 121-150 ensures your pump circuit delivers fuel exactly where it needs to go, when it needs to get there.
