formula for Jet Fuel expansion/summer heat ?

[satpak77]

I googled this and couldn't seem to find it

does anyone have a formula to calculate Jet Fuel expansion ? We had a trip which involved us topping the King Air off fully, to the rim, the other morning, expecting a wheels-up shortly after top-off.

Trip cancelled, plane sat on hot ramp (KSAT), temps 35C+, fuel started leaking out.

Does anyone have a "the temp is XXX, reduce fuel load by YYY" to prevent this ?

Next time we are just gonna top off 100 LBS below max each tank but I was wondering if anyone had a more scientific way of doing it.

There's a formula here: http://physics.info/expansion/
