The O-ring = designations I provided are the industry designation:

908
These are for the = hex plugs, poppet valve bodies, and spool.

 The Parker pump kit (634412) went from $60 to = now $123.  In a direct email to
me you indicated the = o-rings of interest are 013N90, 014N90 and 908 durometer
90 (from McMaster) Thought I'd try and share that info with = the rest.
 It appears a blackish seepage is emanating from the = top of the pump itself
and running down the side of the pump into = the reservoir. I haven't
investigated it yet by taking it off the = adapter.
 Also, been looking at gages.  So far 1 1/4 = inch is the smallest and
electric/sensor = driven.  Hydraulic driven directly at that size only goes to =
2000psi and only good for 115% over pressure.   It appears to me that with
over temps = driving, we would best have at least 3000psi capability.   = What
have others found??   Also, if hydraulic-direct gage = is used with a 3 foot
line will the air purge itself out since there = is no return line??
