This is the pump. https://a.co/d/0cikFTPh There are videos on how to swap it but it's dead easy. Unplug. Remove the back. There are two screws holding the mirror mount. Then snip the wires, solder in the new pump. That's it. If you want to take it apart further and inspect the tubes and reservoir that's only a little more work. I just did that with mine

I think I discovered it first in this sub. Also as an FYI: here's another pump. We should compile, like, a list of them. Here's a nice video about a guy testing/replacing one.
