No diesel engine ever had a problem from it's fuel being
too clean.
With that in mind, and after some years listening/reading
several
sides to the filtering/polishing debates, plus some
industrial
experience along these lines, I finally added a pump &
some new lines/
valves so that we can polish (sort of) our fuel.

Sailboats don't have as big a problem; our 2 fuel tanks
are 150
gallons each. The fuel currently in them was pumped in
August last
year. Before that, fuel was stored for up to 4 years....

4 years? Was it varnish?
