Wow! Ok, so I was correct in saying that this has been converted to a wet sump. I verified this by removing left side crankcase cover and inspecting the pathway that leads from the crankcase -> oil strainer -> oil pump -> cover input [B] -> cover output to tank. The input on the cover [B] has been tapped and plugged with a screw, effectively removing the oil inlet to the tank and making the crankcase the sole oil reservoir, or also known as a wet pump. I did not remove this screw for the fear of there being another unknown modification somewhere and possibly starving the engine of oil by moving it all to the tank. If I do decide to keep this modification then I just need to figure out the correct amount of oil to add.
