I too have done this on many motors for many people.
I took pictures on a 40hp powerhead I just rebuilt.
Pictures show the cover that you tap and install a barb on, the drain hole you plug up, and the routing that excess fuel/oil mixture normally makes into the mixture of spent cooling water and then into the lake.
I don’t get a ton at WOT< but at idle the 35/40hp motors dump quite a bit out of them.
I installed a fuel pump on a couple different motors, but kept the 2 line system. The old AIR line I transformed into the new FUEL RETURN line from the barb. I then drilled/tapped a vent system onto the pressure tank. From initial glance, appears completely bone stock. Unless you look closely!
