Vacuum source for fuel valve?

[Canadian8apilot]

Got myself a 78 GS750 for a project bike, and it seems to be all there, but I'm not sure if I put the vacuum line back in the right spot after I put the gas tank back on... I have a Haynes manual, but no luck identifying the spot to hook it up.
There's a nipple on the #3 carb near the fuel "T" but the other cards have a vent hose on them in that spot.???

Thx.
Bill

You can get a factory manual here : (http://members.dslextreme.com/users/bikecliff/)

Single front disk and wire wheels usually (not always) indicates a '77. The jets were different in the early ones and as you're running pods you will need to change up if you haven't already.

Thanks for the thread, folks, I was able to hook up the fuel line and vacuum line.
