I bought my XF less than a month ago, and the IC pump wasn't working. I figured it was dead and ordered a new pump. While removing the stock pump I noticed the plug was very easy to remove, so I connected power to the pump and it worked fine. Apparently, these must be plugged in to work, and it takes a lot of force to get the plug to fully engage.

Anyway, I'd like to get $125 shipped for it.
