Just a guess but that I let looks like a flush mount water inlet.
The tubing tho’ yellowed reminds me of tigon (sp) tubing we used decades ago
On some medical equipment. It’s still used in food processing plants. As for the flush sprayer that’s anyone’s guess.
I think it wasn’t a kit but maybe homemade. But if it works..

It might be a good idea to install a one-way valve if you don’t see one. Just saying.

Amazon sells a kit by Camco. The pictured components look identical except for the sprayer nozzle inside the tank which I cannot and do not want to see.
