OR, i presume you are using the 40 psi switch; what about the 55 psi switch that might catch dips a little sooner?

I thought about using the 55 psi pressure switch. I think the issue is that the oil pressure would be mostly bellow that, so in effect it would be always open. Today I installed a manual pressure switch "bypass" toggle switch so that I can keep the valve always open when needed. I will test that next weekend at AMP again, this time with PCA. I will set the Accusump Air pressure at 15 psi. This should give me 1.5 qts in the Accusump @ 60 psi, then 1 qt @ 30 psi, so about 0.5 qts to play with in real terms. If you start with 30 psi, the starting volume is 1 qt @ 60 psi, and @ 30 psi, it becomes 0 (empty). In theory, the response time is quicker at higher air side pressures, but you also start with less oil.
