Default Pressure nipple for OS 120 AX

Bill,

I plan to use a Perry pump with an OS 120 AX. Can you install the 140ei pressure nipple in the 120 AX backplate bolt hole as you can with the 160FX? If not, can the raised center boss on the 120 AX backplate be drilled and tapped to accept a 6-32 pressure fitting?

Thanks in advance for your response.

Tony M.

You will have to drill and tap the rear cover for a pressure fitting. Just make sure that you file the inside of the cover nice and smooth so that no metal will project inside.
