Please know all of this is second hand info
as I have never had one on a car. The way it was explained if you are having oiling issues where the pressure is dropping or the pump is sucking air, the pan is not baffled well enough and/or the motor is pumping all the oil to the top of the motor and it is not draining back fast enough. The accusump is supplying oil to keep the pump covered up...better way than adding an extra quart or so and not having one.
Most engine builders will tell you that you can run low pressure (20 lbs) for a short amount of time and not do any damage. You are just trying to keep it from sucking air and having no oil to the bearing.
When Ron (blue 66 mustang) blew his wet sump LS7, it was a combination of a stock LS3 pan, oil pumped to the top of the motor and a long sweeping corner and the remainder of the oil went up the side of the pan and starved the bearings.
