So i just got a used one on sale at a great price, but B4 they shiped it the disconected all the fitting Where does the top tube go? (the one connected to the ball valve), Where does the one on top of the stem go? i think it goes to the needle valve on the co2. and then where does the 90 dagree fitting on the top of the white pvc go?

i know how to set one up, i read that about a billion times. Im asking where those fitting do, and sent stuff to. The one fitting on the stem i think connects to the co2. Then the white ball valve, im not sure where that tube goes and then where the tube on the white pvc goes. i assume one has to be the outlet for water to the tank. The other im lost on.
