140 B20 Heavy duty oil pump

Looking at using IPD heavy duty up grade. Anyone used the spring and the speeve, may not be as big in diam but certainly is longer. What difference did it make8ptXPyxh.jpg Interesting observation that every std spring I have has significant wear makes that would weaken the spring.

    The reason I asked is that I work in fire hydrant industry and have come a cross springs that don't hold oil pressure after 30-90 minutes and need replaceing.
    There's a company in Sydney that makes them.
