91 superjet stock carb setup

I just finished dropping the engine back in the ski. The tape that I had marking the fuel lines fell off. The carb has 2 inputs. Which is intake and return? Top or bottom?

on my carb there is three inputs.. and they go Top goes to the top of the gas tank vent, Middle goes to purge, and bottom gas in line. There should be arrows on the top and bottom inputs showing the flow

Middle goes to purge,

Huh? You mean the middle is for the fule pump and it goes to the engine (for vacuum)?

look on the carb. On the fuel pump cover, there should be little arrows marking which is in and out. And then pulse is the one that isn't marked.

If i remember correctly, the top one is the return (fuel out to the tank) and the bottom is in from the filter. The one on the fuel pump which is off by itself goes to the top of the intake.
Maybe this pic will help:
