Which hose are you looking for ?, as I have a L67 and I just finished replacing the bearings on the blower, and I know every vacuum hose back to front on it.

Keep in mind, the one of the connectors on the Boost/Bypass Solenoid, has a foam like filter on it, "Top port"
where on mine, the foam filter had perished, probably due to the heat in the engine bay,
considering it is above the exhaust, and bolted on at the back of the left head, and at the back of a motor, as is always the hottest part, as there is minimal to no air flow, and mongrel to get to, and don't attempt to work on it when its hot.
I also replaced the OEM rubbers fitting that the plastic hoses went into, and they had perished and causing vaccum leaks, What I did, was go and buy some Vacuum hose from Supercheap and replaced all the vac hoses, which also stopped vac leak.
Good to see you got it sorted.

What is this foam u talk about explain sum more please.
Sorry for the large images,
But its does show you the foam air filter I mentioned on one of the ports on the boost/bypass valve. AC Delco DR152
Where it just slides on the port just like a hose does.
As the first image is the way/position it bolts onto the back of the head.
Where the foam on mine was missing, so I blocked it off ATM, so nothing can get into the port and block the solenoid.
I did think about running a vac hose to the air filter box, and get a brass fitting and connect it on the filtered side of the air filter.
