HP,
Sounds like a great idea. There is one feature I can see a potential problem with. If your drawing
oil from the bottom of the pan with an auxillary pump, your cooling system will be in competition with your
oil pump drawing from the bottom of the pan for the engine. I know it's just recirculating
oil and returning it as fast as it's taking it, but I would consider locating the outlet somewhere above the oil suction tube for the engine. Just so if one is going to gurgle any air it's not the more important one of the two. Maybe it's not even a factor but just something worth considering. Let us know how it turns out.
