Thanks for the info.
Why do some engines get damaged with low pump pressure? Is it because the diesel fuel itself cools the combustion chambers?
My naive mind expects it would be just like running out of gas/diesel.. i.e. it just chugs to a stop, no hard done.

It's not really the engine that gets damaged it the high pressure injection pump. Excess fuel from the lift pump keeps the high pressure pump cool. It's only on the earlier doges that I know of.
