Jon,
My 2,000 psi gauges have worked just fine for the last 8 years.
Here is a photo of the gauges at a point when the gear didn't come down.

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.
Doesn't sound good for a motor. Burned up grease?
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??
