I would bet that your diesel fuel and possibly the tank inside surfaces will be filled with and/or covered by crud from whatever living or dead bacteria, etc. that can live in that environment in the boat's climate.
Before you get the engine running, I suggest you 'polish' the fuel yourself or get a marina to do it--plus I would eyeball the insides of the fuel tank. Better yet, you might want to discard the old fuel and clean out the tank insides before adding new fuel. If you want to polish the fuel yourself, add or use an electric fuel pump and pump your fuel thru a Racor or similar fuel filter/water separator and send it back to the tank before you send it to the engine fuel filter. You may have to change the racor element during this 'polishing' a few times depending on how much gunk is in your tank/fuel. If there is significant gunk in or on the tank, you will clog your fuel filters in a hurry and likely at a most inopportune time! Much better to solve this potential problem at the dock!

Anyone know where I can download a full repair manual? Ideally, I'd like to find one free, as I know there is a full manual on board, but I want to begin reading everything I can before I take possession. In talking with the surveyor, he indicated that these engines are pretty good about not needing the fuel system to be bled after changing out the racor filter if I fill the bowl with fuel when reassembling it. Can anyone here verify that? I'm new to diesels, though I had a 1977 27MKIII for 16 years with an Atomic 4, and am very comfortable with doing work on my boat(s), so I'm guessing I can learn what I need to. The boat's been basically sitting for the last 5 years, with the last oil change having been done in 2011, and it only having 30 or less hours on the engine since then. Before we leave the dock I want to change the oil & filter, change the racor filter and engine fuel filter, change the transmission fluid, and change the coolant. Beyond that we will clear all the strainers. I'm guessing that I'm not thinking of something (solely related to the engine at this point). Anything else I should do?
