How can fighter jets fly upside-down in regards to the fuel intake

Question

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.

Fighter jets fuel intake does not work on gravity like a Cessna 172. They have fuel pumps to pump the fuel.
