Desperately quick help needed

Removed my carb, gave it a clean and fresh new gaskets etc.
Went to put it back in a stupidly cant remember which hoses connect to where cf_emoticons__BangHead:In the engine bay i have a line going to the brake servo and the green expansion tank with a y piece on, this connected to one of the lines
The other connects to the Air filter housing via the tpiece, which links to another of the hoses on the carb as well?
Can someone help out? Its a 1B3 carb
