Help! I took the cover off my fuel/water separator (2010 6.4l) to clean it out, and knocked the three parts out of the top of it (plunger-looking assembly) which promptly hit the ground.

I don't know the proper orientation to put them back in and can't find a diagram online.
Here are the parts:
Here's my best guess as to how they line up with each other:
Can anyone help? I'm a bit concerned about putting them in the wrong way so I'm just sitting here with a disassembled water separator trying to figure this out. If anyone can point me in the direction of a diagram or is able to tell me "yep, that's right," I'd really appreciate it.
Thanks,
Ted
