Seeking Kitchen Sink Faucet Replacement Unit and Advice

[wbmiller3]

The kitchen sink in our 2001 2619 is leaking water into the cabinet whenever either of the knobs on the faucet is turned on. I'm afraid it's finally time to bite the bullet and replace it.

Does anyone have a part number for a replacement sink faucet? Or one that is available from a big box store that fits?

And how does the faucet connect to the pipes? I can actually reach the connections, but I cannot see them. I can feel what seems to be a knurled knob. When I was trying this, the water was turned on in the trailer, so I did not try to loosen them.

Thanks!
