Modern engines and fuel

During our preparation for our adventure, I have come across articles that says that modern diesel engines like the Volvo Penta D3110i in Sally, are sensitive to the quality and of the fuel and don’t like the tiniest amount of water or fuel bugs. It seems that it’s not enough to use the standard 10 micron fuel filter and since we don’t want engine problems in a critical situation we plan to

  • use a Racor fuel funnel to filter the fuel before it goes into the tank
  • put some diesel bug eliminator in the tank when the fuel is about to get old
  • use 4 micron fuel filters in the pre filter system since there is a spare filter that is easy to switch over to
  • do periodic check of the fuel filters
  • regularly check the fuel from the bottom of the diesel tank to see if  there is water or dirt and pump it out if needed

So in theory it seems possible to get clean fuel to the engine as long as the diesel is of reasonable good quality and that I don’t know how to check…
