The pump surfaces are DLC plated, but don't know if every last square inch is.
Does anyone know and then ask if there is any data on corrosion of those non-plated
areas/components within the pump?

AFAIK, only the friction surfaces are coated as coating cost goes up exponentially when you are talking about 3D coating especially with inside surfaces.
Delphi, in one of their DLC bragging rights, talk about how they did a continuous process DLC coating that can coat 3D parts...
Think one of the "signs" of contaminated fuel used in the Ford TSB is corrosion inside the pump --- need to reread that TSB.
Almost certain large number of non-friction surfaces in the pump are not coated --- plain cost too much to do.
