I was changing the fuel filter in our H34 today and I filled a cup with diesel out of the fuel line (when I had the primary raycor off by putting a cup beneath the lines without the filter in place). The diesel was not the nice pink that I expected, it was more the color of red wine. I did not see any strings of algae or anything like that, but I know that this is not right and this diesel is probably too dirty to ignore. We bought the boat last year and the tank was almost full and I do not know the history of the use of biocide, etc. Does this fuel sound too dirty to try the "fuel polishing" that I read about in the archives? If I can go that route, does anyone know of someone around Deltaville who performs this service? Any ballpark costs for a 25 gallon tank? From what I have read, these people can clean your tanks pretty well, so this sounds like a good idea - better than pumping about 25 gallons of diesel and disposing of it, installing an inspection port or new tank, etc. Any of the engine sages out there have any thoughts? Thanks for all the help in advance.
