I probably didn't do a good job of asking my last question - why
bleed injectors. I didn't mean that we shouldn't bleed the fuel
lines, only that my understanding is that once fuel is properly
through the high pressure pump, there's no possibility of an air
lock. Bleeding, as I understand it, should be done starting with the
tank and working toward the engine. The last point to check for air
bubbles is the point where fuel enters the injector from the high
pressure pump.

Universal "marinized" Kubota engines. The same engines are marinized
by others today: Beta and Nanni to name two. The Kubota is a very
strong engine, often seen in farm and industrial equipment. It
should last a lifetime!

As you've already heard, this is almost certainly a fuel filter
problem. The quick solution may be to change your filters.
Long-term solution may be to clean what's in your tank and ensure
that what you add to the tank is properly filtered before you put it
in. Some providers of diesel have old, very dirty fuel. Diesel,
unfortunately, is a very friendly growth medium for a lot of things
you don't want in your engine.
