Ref:  Pilot Supply Plumbing
Piping Ass'y 100 029 768
Hose assy  100 035 255
Do we have a check valve(with drilled hole) in the pilot supply piping?
I could not find any on the prints, and I don't think there is one on
the pump manifold.  Our accumulators (38 660 403) for pilot is down at
the end of the hardline.  If the main pressure drops suddenly, can the
pilot supply hold the pilot pressure a short time,  30-60 seconds or
more(longer is better)?   Would there be an easy way to add a check
valve where the -20 hose from the pump goes to the first PP manifold on
the frame?  Tom Kaufman
