Description
A worn or undersized accelerator pump discharge nozzle will rob your carburetor of crisp throttle response and consistent fuel delivery off the line. The Holley 121-25 is a precision-engineered replacement that restores proper atomization and tuning stability in your carb circuit. Running the correct nozzle diameter ensures your acceleration enrichment system works as designed—critical whether you’re fine-tuning on the dyno or demanding full power at the track.
