I could also be totally wrong on my understanding of a jet pump, it's happened before.

You are correct in some of that.. the factory setup includes a small swirl/surge can and the pump is submerged inside that with roughly 1qt total volume (including that displaced by the pump and the plastic bits). The factory stuff feeds into there so the pump doesn't just become exposed and run out of fuel in every turn. How long does it take to drain the sump and all that? I don't know the answer there. but the jet pump thing basically works to help keep the swirl tank full. it's ALSO fed from the left side of the tank so it's not just the little jet pump thing from the right side.
I have a stock pump assy sitting on my workbench if you want photos, but it'll have to be tomorrow since I have some plans today and tonight.
