What you have is a generic pump from china more than likely. Its built along the line of a FAIP pump. They arent supposed to have the oil changed in them at all. Most are sealed pumps but may have a plastic plug in it. If you must replace the oil then I would suggest Pressure washer parts catalog quick links Pressure Washers High Pressure... and get this item 4.5 OZ. AR64545 OIL FOR AXIAL PUMPS. It is recommended for pumps built similarly but not for your specific pump. But it should work. Good luck. W
