All my fuel is cold upflow filtered, and using water absorbing polymer for 'polishing' instead of wood chips.

My stock winter fuel mix is 50 parts BD; 35 parts Kerosene/jetA/D#1/stove oil; 15 parts petrol/gasoline (<E5) [Summer mix has 5 parts petrol; 10 parts clean, dry UVO instead of all petrol]

The fuel mix is circulated through a column of polymer water absorbing 'crystals', until a sample of the mix tests to <50ppm H2O. One or two passes is generally enough.

It's stored at ambient outdoor temperature and the inlet of the fuel dispensing pump is kept in the clear fuel layer as the HMPE components settle out on the bottom of the barrel as the temperature drops.

Final filtering is through a 5µ string wound filter cartridge and into the vehicle tank. The final filter lasts for years.

The fuel mix in the vehicle tank is adjusted with pump diesel for the ambient operating temperature so that the fuel mix in the tank does not gel. The mix in the vehicle tank varies from 15% BD to 50% BD seasonally.

It's been down to zero F already this winter and the fuel mix in the truck is crystal clear, with no 'stuff' settling out.
