Damage to Bottom Water Filter on Keurig K40, can I fix it?

I would like to know if my Keurig K40 is fixable? I need a new water reservoir, but is it possible to fix the water filter valve? Can I get the parts?

Or should I just buy a new Keurig? It seems like a waste to toss it for an otherwise operating Keurig. I also don’t mind a challenge.

I found a part on eBay that seems like it might do the trick, but I’m not sure this one will fit the K40. KEURIG K2.0-300 Replacement Parts Water Tank Intake Valve Switch Coffee Maker: https://ebay.us/HltMx7
