| Yep, the official count is 18,448lbs internal. Not quite sure why the TechOrd shows something different unless one of the smaller tank groups has been intentionally deactivated somehow for some reason. It seems to odd to me too that an official pub was that far off. |

| I think djcross has it, the other 1600lbs is unusable fuel that will be trapped in the system even if the engines are starved. |

That's sounds like lousy design since you've effectively added 1600lbs of ballast. |

It's 18,000 pounds internal. It's all usable if all the fuel pumps are operating normally. |
