Interestingly I was looking at a boat with a broadly comparable system yesterday. The owner made the sensible case that crud could accumulate and not come through the fuel lines until you're one day into a nasty passage and the vigorous agitation has released it in quantities to start clogging filters.
Good discussion and comments.
If you have flat and level bottoms on your fuel tanks, don’t turn over much fuel and buy from iffy vendors then an inspection every few years likely is warranted. A good check for those of us with fuel fills that go straight into the tanks from the deck is to use a dip tube to see what may lurk, if anything, in the tank bottoms.
Diesel tanks that were routinely filled decades ago with high sulfur fuels are prime targets for crud. Newer boats who have seen low sulfur fuels not so much. The first clue as to tank crud is an unusual vacuum increase on your primaries.
IMHO if you’re the 3rd + owner of an older boat a tank cleaning and/or inspection is a good idea, plugged filters or not, makes sense
