[DMCForum] Re: Air system/mode switch question

Okay, I think I'll go out and get one of those.  I believe I may 
have another vac problem somewhere but I'll save that for another 
day.

With the actuator off I am getting suction on hose one only.  I'm 
was thinking that normally all hoses had suction and only when the 
hose is selected that it opens the line.  Is this correct thinking?
