  8. EZ3040 replacement pump

    can I use this Model# NSZW3540 pump to replace my ez3040 pump.

    I have a need to reduce water volume.

    Roy

    1 answer

    1. This NorthStar Pressure Washer Pump will attach to any 11 horsepower engine with a 1 inch diameter shaft that is 3 -31/64 inches long. The bolt circle on this pump is 6-1/2 inches. These attachment specs are the same as the EZ3040 pump so it is a suitable replacement as long as the other components of your pressure washer(hose, gun, etc.) are rated for the higher psi of 4000.
