99 750 Carb Help

[orlandofast1]

 Just want to make sure that I am reassembling correctly. I looked for a carb hose diagram, but could not find one. My carb has 4 inlets/ outlets. (1) on each side and (2) in the center of the carb. I thought that one in the center was the supply. The (2) sides were drains and not sure what the other center one was for. HELP?

Vent.  The line should have a filter on it.
