As a general rule you probably want the fuel tank closest to the CG to drain last.

In the 190 The AFTer should be drained first, in F then the MIDdle. Draining the ForWarD tank first like the Spit's TOP tank causes oddities in handling especially on the knife edge.

Does HiTech have all of this included in the flight models for the various in game planes?

Yes. It's obvious in the P-51 if you don't drain the aux tank first.

How about the rest?  Perhaps HiTech could answer and clarify for across the board.

I like to drain the left wing tank in the F4U-1D first and leave the right tank full until the main tank is empty to help with the torque roll in turn fights.

other than that the automatic control works pretty well, for instance the P51 is known to handle quite poorly with the AUX tank full of fuel and this is what the automatic system uses first.

You really wouldn't want your main tank empty in the F4U-1 or F4U-1A (the only 2 F4Us with wing tanks) because you barely have enough time for a good turn fight, let alone time to land.....

Ideally, in the -1 & -1A, one would drain their left wing tank down to 1/16th and then drain the right tank down to 1/4 full then switch to the main tank... This helps with roll-rate in both directions and one does not have to crack the throttle as much in a right hand turn as much as they would if the right wing tank was full.....since the F4U-1 & -1A turn better turning left....cracking the throttle to 95% to 90% while turning right compensates for the torque and allows the hog to turn better...

Hope this helps

I think the zeno's film mentions that the F4U wing tanks should be burned first because they were not connected to the fuel gauge.

I've heard this tail or that tail over the years about fuel tanks, some I've tried and some I have not. I do not discount that there is a difference in specific cases but I wonder if some claims come from superstitious reasoning.

@FLS - Out of the planes you are familiar with the most, do YOU have any preferences in fuel burning order? :devil

I do believe the P51 claim on burning the AUX first, which I recall the fuel auto selection doing so last I played.

I think in general for handling considerations the fuel tank closest to the CG should burn last but it also makes sense to have some fuel in more than one tank in case you get a leak.

I also think you should verify any benefit for yourself by flight testing so you know the specific effect if any is noticeable.
