boost and power brakes question

ok, so that fitting at the grommet on the brake booster where the hose to the manifold attaches, is a check valve then ?

well....kinda feel a bit stupid now. just went out to the garage and had a look at THAT fitting, and well, it is a check valve. thought it was just a plastic elbow. never really looked at it before.:mumum:

any who ....merry xmas and all the mopar best for the new year
