Considering the great advice from Chris and Rob, I got under the car to make sure the hoses were tight. The hose from the reservoir has a typical hose clamp. The other hose has the banjo fitting going to the steering pump. Both of these hoses were bone dry. The forward end of the box has a set screw (allen key) with a jamb nut. There was a drop of fluid under that at the bottom of the box. What would happen if I loosened the nut and turned the set screw tighter? That's where I have my very slow drip leak.
