I prefer to keep the accusump on the other side of the filters and oil cooler. There is no need to provide constant oil to them, the important part is keeping oil flowing to the motor. Besides, if your oil cooler gets crunched or takes a stone the accusump close to the motor inlet will kepp oil flowing to the bearings while you get off line and park the car. If the accusump is before the cooler your bearings starve for oil as it all goes out the hole in the cooler.

Generally speaking the closer the backflow valve and tee is to the main oil gallery the better.

Matt, your points are well taken.
