Carb Help

TXPaul
I disassembled my 81 CB750 carbs about five months ago. I finally got some time off of work and went to put everything back together and can't remember where everything goes.

I have a vacuum line and a Fuel line that I just can't place.

Can you guys help?

I think they connect to each other.

 There are two small connections on the Diaphram.  One is for the vacuum that comes from carb #2.  It's the other one in question.

I believe it's a vent.

I have an 82' 750 which i have just rebuilt the carbs and now synchronising them.

The two connections your arrows point to are vents, the one in the middle of your carbs i have another tube connected which routes over the airbox. The other vent is just left as it is. Hope this helps!

I do not have the small brass one you were wondering about on my '80 (hope I'm not missing something).
The other black plastic part on my bike was not connected to anything.
