Reinstalling purge valve on Infinity 1220 LC system - metal gasket and o-ring?

I'm attempting to re-install the purge valve on an Infinity 1220 LC system after replacing the purge valve frit. The nut, an o-ring, and the metal gasket have come off the purge valve body, and I'm not sure the positioning of the o-ring and two-piece metal gasket relative to each other. I can't seem to find a diagram of these latter pieces online or related documentation. Thanks, in advance, for any help you can provide.
