IMO fuel polishing systems like this don't do much good. If all you have is a little bit of loose sediment that gets stirred up underway, the Racor will take care of this fairly easily. Most diesels return 2-3 times as much as they burn, so after going through a half a tank of fuel, most of it has passed through the Racor.


But if you have significant sludge, algae gel, etc, a fuel polisher won't get it out. You need to empty the tank, maybe cut an access hole or two and get inside and spray behind the baffles and around the pickup tube to remove the gunk.
