I was under the impression that fuel systems are treated rather generally as one
big tank in the game.
I recall an experience in a TB-3-4M17 which suffered a fuel leak in one wing and some while later had all four engines cut out simultaneously. No fuel left in the gauges... Now, while I'll pay a TB-3-4M17
not having self sealing tanks, one would suspect that there would be a multitude of individual tanks and valves/plumbing to prevent this sort of thing happening on the real thing.
I'd be interested to hear what the situation in the game actually is.
Still, as BadAim points out, it's not doing too badly for a sim that was designed around one featured aircraft over a decade ago...
