"Fuel Magnets"
I have run big Yachts for years and over the past three years have used a unit which is sold as 'Algae-X' and is installed in-line before the primary Racor.It is supposed to improve diesel fuel by removing the algae which is in all diesel (at least where we operate).I has to be cleaned sometimes,and it seems to work,witness less filter changing etc.The unit has magnets inside----which do what......?Anyone know how this works?
