Check your figures...
1 & 4 mains on a 744 holds 13,400 kgs at .795 sg
2 & 3 main 37,300 etc etc
You figures look close to a simialr figure in pounds..
To the original poster of this thread. Do you want volume or a KG figure of tank capacities. eg Many A330-200 have a limited center tank capacity due to max TO weight rating etc
767 also have varients of CAT capacity
