Guam
Perhaps I wasn't clear - all 747-400/-8 aircraft structurally have a stab fuel tank. But on Freighters (and some passenger models) it's not functional as a fuel tank - the sealing, pumps, fuel lines, etc. are not installed. Further, when a passenger model is converted to a freighter (e.g BCF), the stab fuel is disabled and most of that equipment comes out to save weight.
A 747-400 with full tanks (but no stab fuel) can carry ~ 180 to 190 tons of fuel (depending on density - about 53,600 US gallons). Stab fuel adds another ~11.5 tons (3300 gallons), or about a 6% increase. I don't know why you'd need stab fuel at ~130 tons unless as JammedStab notes it's for balance.
BTW Guam, why would you need full CWT fuel (again, ~185 tons) for a 9.5 hour flight?
