If jet fuel is full of water, how do you get it to burn? When I took
chemistry, hydrocarbon fuels contained .... drum roll please ... carbon
and hydrogen. No water of any level of significance.

Jet fuel, kerosene, diesel fuel, are all hygroscopic. That means that they
have an affinity for absorbing water. Great amounts of it. If they absorb
enough, then it will not burn.

This is one reason why you don't have to sump jet fueled airplane's tanks.
There will be no separate water to drain.

I do take some deference to Jim's saying that jet fuel contains significant
amounts of water. They try real hard to keep jet fuel dry, because it they
didn't, it would start to freeze out, while in the fuel, at altitude.
