Default Lt1 power steering line nut size? 16mm or 5/8?

I've read a bunch of different post about this and I've got two answers. 5/8 and 16mm. Which one is the right one? Both of my open ended wrenches fit it tight, but I don't want to round it off. To reinstall it I'm going to pick up a crows foot or a line wrench. I took it off with a regular 16mm open ended wrench but it was a pain and I thought it was going to strip it. What should I get?

IDK for sure, but would be more inclined to say it is 5/8". The 5/8" is 15.875 mm.
