Thanks, I found it. It turned out to be a loose hose clamp at the fitting
on the top of the pump. I spent a lot of time looking at and around those
bolt heads. I used a bright light and an inspection mirror.  I played
around with the position of the light until I finally could see it
reflecting in a drip trail, which lead to the leaky clamp. Very hard to
see, with everything else that was in the way.  I�m happy it was so easy.
I was having visions of leaky gaskets or broken studs!
