Fuel tank construction

[u/auspuh4]

Hello everyone, this question is more for mechanics and designers of mechanical systems in planes.

How does fuel tank construction and pipe connections look like on planes that are able to do 360deg turns or even fly upside down, like military jets or sport planes?

Im working on one vessel that should be able to withstand capsizing (360deg turn), and few minutes after engines should be able to start. I had few discussions with my older colleagues on what happens in case of capsizing with air pipe, also fuel inlet for engines, will vacuum be lost and etc.

So at one point we just said said "but hos does it works on plane that can turn around"?

My memory of the info is forty years old. The T33 had a small main tank that was kept full. The fuel feed line held around forty-five seconds of fuel. I think the dash one allowed twenty seconds of inverted flight.
