Bottom = Feed/In from bottom Trans line.
Top = Return/Out to top Trans line.
Thank you, that's what i've thought so i put my finger on the return/in line to see if it has any pressure but i can easily stop the flow, in the other line has a little bit more pressure , i hope that's enaugh to create a flow in the circuit cooler otherwise it's a problem.
