Hawk Oil cooler install questions

Working on an oil cooler upgrade and I got the bracket made and position right with some work as it is tight. The cooler is the oil pump style I think about 186 ml with an in line filter.

I read the thread on the oil cooler and watched JerryHawk video but I want to be sure about couple things not knowing these CB engines.

So set up talks about pumping the oil from the bottom of the cooler up through the top to avoid a check valve. What is the pressurized side of the cooler inlet adapter? Appears it would be the center inlet stud with seal on the end correct? The outer would drain back to the engine sump?

Pumping up through the top of the cooler then when the motor is stopped the top drain line drains back to the engine sump?

So when you install the cooler then you need to use the syringe to fill the cooler from the top until its full which will fill the drain line back to the pump inlet to get the amount of additional oil added to the system?
