Hey guys, I followed this thread to get started on adding an oil cooler to my 1980 kz650 . I have the zephyr 750 oil pan, lines, and cooler. I have a derale thermostat that I am trying to run inline on the cooler lines. My question is, which port on the zephyr oil pan is the flow out? I've been through my manual and followed the oil flow, but when it gets to the oil cooler ports I'm confused. It looks like both passageways are open to one another. Does it matter which one I make the outflowing line?
