Kelly;

I did something along that line on my 20B. Mine is a pusher installation; but I wanted the deep sump near the firewall to keep the weight nearer the CG. I have about a 2” hinged flap between the sloping section and the deeper sump to inhibit the oil from running toward the ‘rear’ on steep climb. Don’t have a photo of the inside, but you can get the idea the old photo attached. Normal full level is about 3/4” below the pan flange giving 8 quarts (designed for pan fed OMP). The level switch warns when the level gets down to 4 quarts.

Now that I’m converting to premix, I’ll probably fill to about 6 qts, and add when the light comes on; which probably shouldn’t happen between changes.
