    what does this hook up to?

    Upon removal of the crankcase vent hose, from the valve cover, the skinny hose was loose. (I don't think I disconnected it previously).
    Where does skinny hose connect? Anybody know?

    It goes under the intake on the opposite side of the intake. Feel around and you'll feel the nipple (NSFW lol).

    Cool

    It goes into the throttlebody , same for the vacuum advance hose on the distributor which is the same size.

    I might have pulled it off unintentionally, as I was trying to wiggle the fuel distributor, and rubber boot out. I see there is a nipple of the right size on underside of the throttle body. Thanks.
