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??
