Info

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 one nozzle and two nozzle gaskets. 

The three styles offered are Tube Type, Straight Type, and Center Type.
