fuel line routing

[gothera]

so my project bike has been apaart so long, i cant figure out where all the lines off the carbs go,...

i know i have the main fuel line from the petcock but i dont know which port on the carb that goes to.
i have the petcock vacuum line but dont know which port it goes too,
and theres another large size port on the carb i dont know what goes on there. ..

i saw something on an answer site that said it might be a spliter kinda deal im missing, so the 1 main line goes to a T that goes to each carb but i never had any of that, i just feel really stupid i cant figure this out, its not on the parts diagrams on bikebandit or in my clymer manual.

this is my first bike and i got a project so im very green on the whole process, i know its something stupid simple but it just hasnt came to me yet.

1985 gs 550 es

its the mikuni 2 duels ( o o ) ---( o o )
theres 2 ports on 1 side and 1 on the other, 2 are flat to the ground 1 goes up at like a 45
