I suspect that the fuel
pumps for the newer electronically controlled "common rail" diesels are
fairly tolerant; but, if Jet-A and Diesel fuels are not fully
interchangeable, then diesel conversions could be very difficult to justify.

This is not to say that some engines are not fully capable of burning jet fuel.
Some are.

It is just saying that you need to find out if multiple people have put some
good hours on the engine burning Jet A, without problems, before you go for it.
If it is out there, it is a good bet that someone has used it. Find out, to
avoid surprises.
