If oil pump pumps no more oil, that is it. If Accumulator is filled again, when you shut off ignition you have fresh oil supply under pressure once again stored for pre-start pre-lube.
I believe that only the Canton has the different pressure calibrated release valves. Not sure.

Ah ha! I did read about the different type valve here.
Do yous have a place were I can find a pressure calibrated release valve? I would use the main electric sylinoid for prelube and turn the system on/off. then be able to use the calibrated release valve? Hmm, gonna have to think about that.
