This is unfortunately very likely with newer common rail systems. The 20k+ psi injection pressure and small orifices are much more likely to get damaged by fuel contaminants. I have been through this with bosch pumps and common rail injectors on road. My last problem was about 5k and virtually every high pressure component in the system was replaced.

It seems like Detroits and other lower pressure, mechanical injected motors are more resilient to bad fuel though which is nice. Regardless, id rather have a secondary pump and filter system take that hit and not use the primary engines as a cleaner if possible.
