Actually jet fuel does have lubrication properties, and most fuel controllers and fuel pumps are fuel lubricated. Operation sans fuel can be very damaging. It's also partially for this reason that many systems operating on suction feed can suffer damage or have life limits.
All diesel fuels are kerosine fuels. Some types of jet fuel are cut fuels mixing avgas or other gasoline blends, some are not.
I've run a lot of #2 diesel in pratts under Ag.
When using alternate fuels, some will require resetting the fuel controller, and in some cases, the use of different fuel nozzles.
The biggest danger of using jet discard fuel is dirty fuel; filter it and check it before burning it to avoid contamination. It should run in your truck or heater quite well.
