Thanks again for the info, this is the last system to complete till I can start the truck up.
So confirmed that "C" is from scavenge pump, "D" is return to dry sump tank.
I would like to confirm "A" and "B" flow direction as in my build I have a high and low port location on my front cooler and would like the input on the lower port and out on the upper port to help clear out any air.
