Holley Accelerator Pump Discharge Nozzles


Holley
Holley Accelerator Pump Discharge Nozzles

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
