To the left of the skirt access door is a high pressure sphere which I believe supplies the jet nozzles.

I believe I've traced the tubing which joins the supply sphere and the pressure regulator.

Picture 1 of 4.

This is the back of the sphere. I believe that the large-diameter tube going straight up runs to the regulator. The mesh desiccant bags and desiccant which spilled out of the bags partially obscure this shot.
