I'm not sure but I know that it was possible to get the petroltank hit and then after a certain amount of percentage loss it stopped, e.G. 17% etc. Can't remember though if it was in OFF. But if it was in OFF, then it is implemented for sure in WOFF too. Haven't had that case for a while so can't remember.

On the other hand I learned from reading biographies etc., in reality, when someone got his petroltank hit and petrol was pouring out, they immediately shut down the engine. Simply because the engine is running red hot and petrol spraying around might have caused the engine to catch fire. Of course it obviously depended on the aircraft and if the petroltank was in the same area as the engine.
