AR Pump RMV2.5G24-PKG Pressure Washer Package 2400 PSI

I had to call Customer Service and asked how to add or change the pump oil. They told me that the RMV's were a sealed unit and that the oil did not need to be changed. With that being the case, you should remove the section that specifies the oil. It is mentioned in two places in the owners manual.

It worked as expected. I needed to change the output fittings, but all went well.
