Biodiesel, a mix of fatty acid methyl esters, doesn't start out corrosive. Instead, bacteria and other microbes hydrolyze it in reactions that ultimately generate hydrogen sulfide and organic acids, Suflita's research shows. These compounds eat into steel and degrade it, he explains. Manufacturers already have to demonstrate biodiesel's chemical compatibility with the fuel infrastructure. But the fuel's biological stability during transport and storage generally isn't considered, he adds.

Now we need to ask the question:
What is the reactivity of DLC / Steel etc. to organic acids????
At 2,000 bars? 150C?
Are we also dealing with break down products?
Are microbes KILLED by high temps?
Do the temperature of the fuel in tank being RAISED in normal operation encourage the growth of the microbes?
Or does it get high enough to kill them?
Pretty likely that a high temp / pressure to pump will kill them... but..
That opens another can of worms --- can the pump be host to a specialized microbe that thrives on the high temperature / pressure that is found in the pump when regularly operated?
