88 5K Hydraulic Pump (Brakes and Steering)

["Christopher Ritchie" <cjr1@gte.net>]

I seem to be losing Pentosin.  Recently replaced the "bomb."  I do not
believe that I was losing fluid before the "bomb" was replaced.  It is not
leaking at the "bomb."  It is not leaking at any of the lines.  I think
(but am not 100% sure) that it is not leaking at the steering rack.  It is
not leaking at the top and at the 3 fittings on the pump.  The underside of
the pump, though, is wet with Pentosin.  The engine area underneath the
pump is wet also.  It seems to leak more rapidly when I stress the
steering.  That is, when I turn the wheel quickly (such as in parking),
especially if the front tires are low in air pressure.  (Both front tires
have slow leaks.  I usually keep them pumped up, but sometimes it will get
ahead of me.)  If I turn the steering wheel rapidly at a stop or low speed,
I can "beat" the power assist sometimes.  Anybody have any experience with
this?  Is the pump on the way out?  Did the old "bomb" mask weakness in the
pump?
