Fuel cap has been leaking so my first step was to flip over the existing gasket and get some measurements while it was out. I really thought I was being careful, but when I went to pick up the internal cover for the locking mechanism to reassemble, a spring and one of the retractable latch pins had dislodged. And an interesting washer with a small hole that doesn't appear to align perfectly with anything, no matter how it's positioned.

Man, there's a lot of parts in there!

I worked with it a bit, trial and error, and I think I have it back together correctly, but would really like to be sure.

Anyone have detailed pics of how these things are assembled?
