Alot of C900 pilots, myself included, add another graduated gauge. Up to 1.5 bar (20 psi) should be more than sufficient for most C900 appications, pushing any more than about 1.1 bar on a C900 is rare and not for the feint hearted! The advantage is it allows you to set base boost properly, suggest you google for base boost set up. You probably just blew the line off the manifold, or as happens with many older C900's the line is perished somewhere. Change all your vacuum lines for silicone and you'll never have to change them again. I got really anal and used blue for vacuum lines and red for the cruise control circuit. Good luck. Al
