Vacuum hoses behind the brake booster.

As part of the preparations (and usual last minute trouble), I heard a vacuum leak in the 4-to-1 vacuum connector. Today a disconnected each vacuum hose to check for leaks, and found the Black/White (or grey?) hose leaking vacuum possible from the source.
This hose connect to the yellow vacuum check valve in the middle (2nd from the left) just behind another Black/White (or grey?) vacuum hose.

Anyone know where this vacuum hose leads to? I think it goes to the supply tank or a change over valve... but I really don't have time to disassemble things, need to finish the detailing : /
