    A wide selection of discharge nozzle sizes is invaluable to properly tune an accelerator pump system. The hole size determines the rate of discharge. A larger hole will shoot fuel at a faster rate with less pressure than a smaller hole. Nozzle sizes are stamped on each shooter (for example, a 31 stamp indicates a hole size of .031'').

    *2 gaskets included unless otherwise noted

    121-147 - Holley Accelerator Pump Discharge Nozzles is rated 5.0 out of 5 by 1.
