A properly plumbed accumulator will use a one way valve or drain back filter so the oil is pushed from the accumulator right into the main galley. Payton is right, it will lube the crank and fill the pan so the pump doesn't cavitate. There is a pressure gauge on the accumulator with the manual valve. You just subtract the 6psi precharge off the total. I would simply rev up the engine with my right hand and close it at say 60 or 70 psi.
