Details
A good selection of pump discharge nozzle sizes is indispensable 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 with less pressure than a smaller hole. Sizes are stamped on each nozzle. For example the number "31" indicates the nozzle hole size is .031".
Includes two nozzles and four nozzle gaskets.
