How are the fuel lines reconnected to the carburetors on a 1980 Kawasaki police kz1000?

Took them out and apart a while ago, rebuilt, and set aside till I found the other parts I needed. Lost one of my trays that had my upper fuel lines and my phone with the pics broke. Have 3 plugs on my fuel switch into the tank, bottom is capped off, middle is larger line and runs to the main T in the middle of the carbs, and the top lines out of the carbs are running smaller, 3/16 fuel line and co-incides with the top line on the switch. Farthest 3 carbs from switch all have this line ran out of the top front but I can't remember how or where they went. Do I just T all 3 together and run to the top port on the switch?
Sorry, ran out of the back and top, not front top. Thanks
