I have a little different school of thought on starting and running an engine with an accusump.

If you start the engine with the valve open and the accusump empty it takes awhile for a cold engine to build oil pressure because the accusump will be filling the same time that you want all the oil going thru the motor.

I like the manual valve because I can keep it closed when starting the engine and then open it slowly only causing a slight drop in oil pressure when filling the accusump then leave the valve open for the rest of the day.

I run a 1 1/2 qt accusump with the engine at normal oil level, 7 qts with a 7 qt pan and nothing extra for the accusump, this lowers the oil level in the engine during the run, reducing splash and increasing HP.

My problem was losing oil pressure in the traps and using this procedure solved that problem because as soon as oil pressure dropped on shutdown the accusump would push oil back into the motor keeping the oil pressure up till the oil in the pan stabilized.

IMO it's like having the best of both worlds, steady oil pressure and a low oil level.
