Me and my brother are at a loss, we understand the basics of how the upside down thing works, but how does the engine get fuel when the tank is turned around, is it a vacoom and how would that work or is the intake from the tank in the back of the it, so the fuel is forced into the engine? Thanks.

A few possible explanations here. They mention two primary ways:
1: Flop tube, a flexible tube with a weight at the end, making sure the tube follows the liquid around inside the tank.
2: Balloon, an internal pouch or rubber lining that shrinks with the amount of fuel. No air no problem, right?
