It's possible that you haven't yet rectified the root cause of your initial failure, the sheared splines on you 8V92 output gear. Your new pump may have failed for the same reason. Do you have an ultra close-up photo of the fractured shaft? Any gate valve that you install will need to be rated for 5000 psi.

Thanks David.

First thing John Boy Hughes did after removing the first and the second hydraulic pump was to check the splines in the DD output gear. He reports no damage and there was no damage to either of gears of the secondary assembly on the pump. I should have taken a pic of the damaged pump shaft, but John Boy took it back with him.

Do you think a gate valve would be an alternative to the extinct hydraulic solenoid? I have even thought about adding a pressure gauge aft of a gate valve. You probably know how lawyers think.....
