where did it go? Fuel regulator hose

[supercoupe1993]

Ok, I pulled the tank off of my 2000 Tiger. Pulled the air box and replaced the spark plugs. Upon reassembly I realized I lost the small vacuum hose that goes to the pressure regulator on the fuel pump plate. Can someone tell me where the vacuum hose comes from so that I might start looking at that point and see if I can find it? Also, do I need all of the extra corrugated vacuum stuff? carbon canister? I think one of my problems is that I am missing a few of the hoses as it is.

Thanks for any help,

It was deleted on later bikes so you can safely leave it off. Its purpose is to sense ambient air pressure as a reference point for the pressure release valve so it doesn't matter if it just sees the air pressure where it is.
