I'm using a new kind of sprayer so the new top won't fit the old base.
I figured out that I could get the retaining clip off using tweezers.
:-) If that didn't work, I was going to just bite the bullet and spend
the $20 to get an entirely new assembly that included the hose. That
would have been more cosmetically appealing because the new sprayer is
a cheapie that doesn't match. Oh well, it works for now.
