Most jet aircraft have heated fuel tanks and or use PRIST.
The fuel control units are heated by engine oil or electric
elements so the screens stay ice free.

Yes, I do know all of that, but do smaller jet fueled planes (Malibu and
smaller) have heated tanks? I still say that they try real hard to keep
water away from jet fuel, and the amount of water added to the contrail
because of water in the fuel is a small fraction of the water released from
the combustion process.
