Hey that's the thing you need to move slightly! See how there is a screw right about the clip for that tube? I took that out. Also, in your first pic, there is a plastic thing immediately to the right of your hand, with some tubes coming out of it. Detach that from its position and you should be able to get a hand in there to the seperator. I think I used a torx tool that has a few that fold into the main body to get a good angle on it.
