lol, thanx for calling it my "style"
I've never seen one... enclosed... quite like that. Have you looked under the car and inspected for easy access there? You can actually loop the lines TO the rack FROM the rotary valve, if that makes it any easier. I edited your pic for a basic idea of what I'm talking about.
The looping serves 2 major functions: to keep out the crud and to (very mildly) reduce the effort to turn. If you leave both lines open and you turn, you are pumping air out one into the open air and sucking air into the other. With the line looped, it should lessen this effort. Now, if one can actually feel a difference between looped and open, who knows. If you leave them open, just cut up an old shirt or something and zip-tie it to the end. Anything to help keep it clean inside, especially if you ever want the option to go back to a powered setup.
