From your posts, everything sounds straightforward. The only part that confused me was adjusting the one-way valve. The way I understand it the valve should have zero resistance(of course it will always be some) when air goes one way and should block any air trying to go the opposite direction. I didn't get the point about "limiting the back pressure to -8 to -10psi." Could someone clarify this moment, please?
Troy is making a new CCV kit, should be out in a week or two, once its out, i would get those missing items from him or the whole kit, whatever suits you.
