Sadly IL2 does NOT simulte the locations of the fuel tanks with it comes to weight. Fuel weight is evenly distributes the weight of the fuel over the entire plane, which is just one of the reasons we don't see what the RL pilots saw when flying the P51 with a full rear tank.

It does simulate the locatin wrt taking hits that cause a fuel leak, but at that point the fuel weight is evenly subtracted from the total weight of the aicraft
