Your right about the constant fill capability of the solinoid valve. But you defeat half the purpose of the ACCUSUMP by shutting the valve when you do. It is there to maintain constant
oil pressure in "adverse" conditions, such as long hard cornering (see highway ramps)when the
oil goes to the top and doesn't come back down. Or how about the possibility of taking a good one in the oilcooler from road debris (or the
oil pan for that matter). I holed my oil pan once, and it saved the motor. I have also had an oil line burst at an inopportune moment and I was saved again. They cost enough, don't waste half your investment.
If you have CRS like I do, wire the hot side of the manual switch to the IGN.on post and it will lock in pressure when you switch off the key and release it when you turn her on.
