SO you see it is not easy to know exactly what you have there. I would hesitate to have you put the wrong oil in a system or follow the wrong procedure and cause damage.. For example the oil filter is filled with oil right to the top before you install it. There is a reason to do this. the engine can possibly be ruined if the filter is installed empty. (my Saturn oil filter is horizontal so you cannot fill it prior to installation and with such a small filter the engine picks up and works fine). Fuel filters need to be filled and the system purged of air before the engine will start . If you run out of fuel and allow air in the system it gets interesting . .......if you have no idea what you are doing; get help.. Sorry to be a damper.. your enthusiasm is great. happy bussin mike
The power steering filler on my MC9 is just a screw (thermos) plug. No dipstick. The sight glass is the level indicator. That gizmo on the tag fender well was also a drain. It should be plumbed so that it can be drained. The disconnect can be swapped for a male fitting and a small ball valve installed. The ability to air up the coach from there with shop air is handy.
