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?
Yes. That has not been ruled out.
The ASTM standard calls for .05% water and sediments by volume in diesel when it is made.
But, in the filling station storage and customer fuel tank, it is hygroscopic and that number can go up quite a bit.
Because fuel is heated as it is used -- that cause more water to be absorbed from the air if a tank is repeatedly used and filled partly.
What bothers me is rust in the pump is a key piece of evidence used to blame customer for fuel contamination.
The question is, can visible rust form from normal fuel as opposed to contaminated fuel?
