FSX:SE Thomas Ruth A330-300 centre fuel tank

[HighBypass 2,339]

So I only recently found out about the centre fuel tank option on the real A330: The -200 has been using it since first flight, but only in the last few years (5?) has the -300 had the option to make it wet. How easy would it be to update the config to reflect this option?

I had set up an Air Caraibes -300 flight from Orly to Guadeloupe and online flight planner gave the fuel as more or less maximum  - I'd actually misread the trip fuel as 177161 not 117716 lbs!  Thinking that no way would they allow the trip with no reserve capacity triggered my investigation.

I could just paste the extra fuel tank line from the -200 to the -300 config but its longitudinal position from the datum would be wrong, but how wrong?

Any ideas please?
