I had the same problem with my Escort. The PS hose was leaking at the pump. It was in such a tight place I couldn't get a wrench in there to tighten it. Going up from underneath I put a pair of Vise grips vertically on the fitting and then used another pair of vise gripes to turn the top one. Worked like a charm. I've put 70k on it since and it's never leaked. To be sure about where it is leaking, I would hose it down at the car wash, then check for where it is leaking.
