Oh my....could it as simple as that the innards of the pump is bare steel and
H2O rust's it, to then have cavitation agitate iron oxide particles to float
into the DLC coated areas ???
Just plating the pump innards would solve that one
But then, why did the previous pump not have this issue too?...or did that gear
pump prevent cavitation ?
And back to my theory. If the very first fuel these engines are fed has the normal water content expected in diesel fuel, then the engine isn't run for some time, isn't it possible enough rust could form internally to cause a problem?
