Filled my cooling system tonight, where is the "cold fill line" in Moroso tank?

Tonight I filled my cooling system. I poured just short of 4 gallons of the Ford orange coolant/distilled water mix at 50/50. It went in no issue and could hear it bubbling and filling the system. I stopped about 1 qt short of 4 gallons and the Moroso tank looks to be about 1/2 full at this point. I figured I would stop there and after first start, and then after cooling, I will check the level in the tank and top it off. But where is the "cold fill line" in this tank. There is no sight glass or anything that I can see would indicate a level. What do you think?

Mine is filled cold to where the top gets wide.

I took my cue from the stock tank. It has "MIN" molded into it exactly in the middle. So half full. "MAX" shows 1/2 inch or so above it. I'm assuming that's cold. I run my Moroso tank just over half full and haven't ever had an issue.

Looks like we have different MOROSO tanks. Mine is filled to the bottom of the left edge in the picture

Alright thanks for the info guys. This was surprisingly easy to fill with it plumbed this way. I read a horror-story thread of others having a heck of a time with air in the system so was very happy to have avoided that.
