One of the avenues I am pursuing is whether we are dealing with supercritical fluids in the HPFP at the temperatures / pressure being experienced.
We know very little about what goes into the "secret sauce" of additives added by biodiesel makers, let alone aftermarket additives and other additives added by the fuel refiner / terminal.
Is there some component of that that can become supercritical?
If so, the behavior of such a fluid is often completely different from its behavior in normal phases.

Such behavior cannot be predicted by current (ASTM 2011) published tests for fuel standards.
It also opens up the possibility of cavitation eroding the surfaces and damaging the coating, in addition to the previously discussed issue of reactivity.
I am investigating... you will know when I know.
