Since the switch to ULSD, many users are going through fuel filters like there's no tomorrow.. many people labor under the impression that ULSD is a solvent, which de - laminates the layers of gunk in the tank until the fuel quits running through the filter..
that explanation sounds plausible, until the filters clog on a new truck or bus..and if the clogging happens over and over again, how could the engine ever have run right, if the fuel system was loaded with enough gunk to cause so many filter changes?
actually, sulfur ( being an acid ) is what kept bacteria, fungus, and yeast in check. with the removal of sulfur, ULSD is a playground for contaminants to grow... so the chances of filter plugging go up exponentially with this new fuel.
here are some pictures of a yeast infested filter.. this fleet operator was changing filters about every week, due to the slow fuel flow..
this stuff likes to grow in biofuels too, as they absorb water like nobody's business..
anyway, we fixed this guys problem, but the moral of the story is,a quality biocide /fungicide / yeasticide can put a stop to all this nonsense..it's the fuels fault, but not in the way everyone thinks..
