There's a 1982 Knight & Carver trawler with twin 3208s and two 20kw generators for sale in California for $250K. I'm not in the market, but K&C is one of the quality builders that I like to see images from because I might see something new. Here is the filter setup - I don't know that I can follow everything, but it appears that the fuel runs through a Racor, a polishing pump, another high capacity filter, another high capacity filter, and a commercial style totalizer. I'm guessing that the hand pump in the upper right is for remotely draining engine oil (must be a valve prior to select sump). And that maybe all those filters on the bottom are for the generators.
