Sorry Nick, but I don't know if or how you can. :( So if you can't change it using ACE, I'm stumped if I can change it. Not only that, I'm not very good with XML (or C⁺⁺ coding, which I think that is what Captain Sim use for the GAU files).

As for the changing from Kilos to pounds, I got that from a this topic: http://www.captainsim.org/yabb2/YaBB.pl?num=1245096833,  in the 757 Captain - General forum

Changes from when it was originally posted are:
757_OH_14_fuel_OT001.XML is now named OH_14_fuel_OT001.XML
and
757_OH_14_fuel_1.XML is now named OH_14_fuel_1.XML, which was a no-brainer for me. ;)

I don't know why the original poster (Necroscope) did not want to change the size of the data readout (fuel quantities and temperature) as they tended not to fit in the gauges very well, so I shrunk them a bit. I did us his brighter color though because I found it easier to read.
