    Need to know the fuel capacities of the B-25 Mitchell Bomber.
    One source lists 2 front tanks of 173 gallons each - total 346 gallons
    2 rear tanks of 150 gallons each - total 300 gallons
    Total capacity = 646 gallons.

    Another source lists 2 front tanks of 184 gallons each- total 368 gallons
    2 rear tanks of 162 gallons each - total 692 gallons
    Total capacity= 692 gallons

    I'm trying to verify which fuel gauge is original the the B-25 B

    Any assistance will be greatly appreciated.

    Where are your sources from? Sometimes folks who put together books forget to include "usable" and "unusable" (or even fail to understand what those terms mean) fuel and based on what you posted I could almost bet that's the problem...

    Hint - the smaller capacity will always be "useable" fuel.....

    That too! Especially on aircraft that went Lend Lease, and we know the B-25 was one of those...

    BTW many "US" flight manuals had both values for liquid capacities...

    Hello: My sources are the actual gauges. Both are are said by the owners to be B-25B gauges. Very few B model B-25's were manufactured and I'm guessing it's unlikely different size fuel tanks were used. I did an internet search and found sites indicating either might be correct. I'm trying to verify which is correct for the B-25B used by the AAF in the US (specifically those used in the Doolittle Raid).
