140 Nissan / Tohatsu vacuum hose question

[boatbonanza]

I was working on my 2004 Nissan 140 and found a vacuum hose from the intake manifold just above the 3rd carburetor (counting down from the top) that was laying loose. It's about a foot long and for the life of me have not found where it connects to on the other end. I looked everywhere within the range of the hose but don't see it. Probably looking right at it but not seeing it. I have a factory Tohatsu service manual, parts manual, and owners manual but couldn't find this hose. If anybody knows where it goes I would appreciate it. Also as a side note this is not one of the 4 recirculation lines, I checked all of them.

Thanks
Kip

Just wanted to update so nobody wasted their time answering my question. I found it. Tiny vacuum port near the bottom of the crankcase, hose had broke off. Just couldn't see if because of the wire harness and cables.Time to buy all new rubber for it.
