I look after several Detroit 71 and 92 series diesel engines in stationary emergency stand-by service. They had been having injector problems which lead to fuel samples being taken. The samples were bad, which lead to discovering huge sediment (mud) buildups on the bottom of the fuel tanks. Engines are in heated indoor spaces and so are the fuel tanks.
Is this just partials dropping out of the fuel over time? How much of it could be picked up from the engine fuel system and returned to the tank by the fuel return line? Has anyone ever heard of adding some sort of filter to the fuel return line?
These engine do way more sitting than they do running, so the fuel does get old. Is diesel that dirty?
Opinions and ideas welcome.
