Hi Flint, Landtank and these guys are the experts but all of the ones I have done take less than 59ml as a matter of fact I'd bet that's too much. I am guessing that there is about 8-10 ml left in the bottle (59ml bottle) when I am done. I just did a black hub last week and decided to leave the O-ring in place, no problems at all, I just put a little film of silicone on it before I put it together, like oiling your oil filter ring. I put it in the oven upside-down on the lips of a pan at 170* for an hour or so then let it sit overnight to drain down. Next morning popped it back in the oven to heat it up a bit, wiped off any residual drips/film with lint free cloth then filled it, let it sit, topped it off, let it sit, topped it off, let it sit, repeat until it quits settling (couple of hours), might even twist it slowly to help it find the nooks and crannies. Back together and in the truck. If you take it off, putting the O-ring back on isn't all that hard to do especially if you put a little silicone in the groove to help it stick, it can be like keeping two cats in a bathtub but once you get one end (or one cat) to stay then you can use both hands on the other end (the opposable thumbs help hold the first end).
For what it's worth, I run 20k in one of my trucks but found that being set at 95 was too low, it was pulling really hard and too soon so I reset it to about 110+ and like it there so far but I still haven't loaded up and taken it to the mountains in hot temps with the Yeti mounted in front of it yet.
