The OP is confused. The 100% system uses a modified pump. The pump has a sleeve inside to prevent oil going to the rear main. A custom plate on the bottom of the oil pump the takes 100% of the oil to a fitting on the side of the oil pan near the dipstick. And one oil line via a modern filter to one fitting at the rear of the block. NO INTERNAL PLUGS!
The 80% system uses two fittings at the rear of the block with an internal plug to direct the oil through a modern filter, and back to the block. Getting them mixed up can have dire consequences.
The use of an 8BA type filter is only used in the bypass filter system where all of the filtered oil is returned to the oil pan.
