Hi All… Has anyone used or have information about a produce named "Walker Fuelsep" (www.walkerairsep.com/fuelsep)? It looks like a fuel filter that refines the diesel fuel to reduce exhaust soot on the transom. My question is dose it work? Any help would be appreciated Thanks Rich Lemieux Amitie, C-36 1621 Noank, CT Fleet 5 & LISCA
