Description
This nozzle can be used with other models as well. This style was designed to combat the condition that is sometimes called pump pull-over. That is, as the stream of air rushes past the pump discharge nozzle it has the tendency to pull the fuel from the nozzle. A good selection of accelerator pump discharge nozzle sizes is indespensible to the proper tuning of the accelerator pump system. The nozzle hole size determines the rate of fuel discharge. A larger hole will shoot the fuel at a faster rate, and with less pressure than a smaller hole. Sizes are stamped on each nozzle. For example, the number 31 indicates that the nozzle hole size is .031. Various styles of nozzles are offered by Holley.
