I've been flying a bit in the C.202 and have noticed that if you take 100% fuel and use automatic change of fuel tanks, it will burn them in the order of AUX->LW+RW->MAIN.
However, if you select 75% fuel in hangar, you will given a full MAIN and partly filled AUX tank (about 75%).
I just figured that either the fuel burn order should be changed, or it should be the wing tanks that were partly filled when taking the 75% option.
To tell the truth, it's not that I can feel any changes to handling whether I manual let the wing tanks burn first or not, so not high priority. Maybe when you upgrade the model
