RR aside, yes one would hope that the engineer would advise of a fuel leak. Not only that, but the large oil slick forming miles behind your boat, aircraft following it in, as well as, warships would be a sure indication that there is a fuel leak. Not to mention the smell would be unmistakable. At any rate, the devs did not address this issue. Furthermore, there are saddle tanks where one could be leaking and the other unaffected. They also used the tank that was filled with water that helped with trim and also helped in quicker dive times. These are not modelled as well. This brings us to the issue of fuel consumption and not having enough within the game to travel at 15 kts like the real submarines did. Just an ugly snowball effect going on here. At any rate, I do not believe there is a work around for this. The best fix right now is prevention of getting holed.
