So…I decided to start with the simple, namely the fuel tank and filters. I disconnected the line between the first filter and the tank and to my surprise, nothing came out. Huh. I blew into the tank 3 times and presto, fuel flow. Reconnected,primed and she fired right up.I then removed the filter. You'll never guess what I found.
So tomorrow I will be draining, flushing, and treating the tank as well as replacing the filters.
My question now is…What would be the recommended procedure and products to clean the entire fuel system? I would rather not remove the injector pump, but if that is what is needed, I am as prepared as I am ever going to be.
Any advice would be greatly appreciated.

You got critters! And because they are brown they are still young and alive!
Ideally you should remove the fuel tank and thoroughly clean it, replace all of the fuel hoses including the return lines, and clean the lift pump and fuel tank strainers. Replace the secondary fuel filter (the one in your picture). Make sure when you refuel that it is from a known reliable and clean source, and subsequently dose the next three fuelings.
There are many fuel treatments on the market. Make sure the one you select contains a biocide. I personally use Hammond's Biobor JF.
Note: The Cyanobacteria (bugs) are highly corrosive and can do major damage to fuel system components which won't be realized for some time so it's very important to keep your fuel clean and dry (no water).

the last 2 words in the post before are very important the diesel bugs can not exist without water so no water no bugs,use see thru bowls on bulk diesel tanks so you can see if water is present,if you do not have a see thru filter system get in the habit of using the petcock to drain off a sample for inspection.

Thanks guys.
Even though I “got it running”, I've postponed orders at my sawmill and pulled the tractor from service for at least two weeks while I collect new lines and filters.
I suppose it didn't help that I bought the tractor without a fuel cap and just tied a plastic bag over it till I could find one. Condensation from rapid cooling and heating would have probably propagated the moisture in the tank. I was advised by a friend to routinely treat the fuel with additives that would help with moisture.
I am obviously spending too much time on the clock and not enough time educating myself.
Apparently learning “the hard way” can be more expensive and time consuming than a little investment in preventive maintenance and knowledge.
Thanks again for your advice.
