Wondering what experience anyone has had with diesel fuel
that has been blocking up filters because of fungus growth, or suggestions on prevention. I have copied below from a BP web site describing preventative measures.
Should a tank become over infested with fungus then filters will start blocking with a black slimy deposit and the fuel
may be hazy with water
and dirt suspended in it. In such cases the biocide should be added to the fuel tank
and then the fuel in the tank should be circulated to ensure that the biocide spreads throughout the fuel. The biocide should be one which will kill the fungus and then assist the water
to drop out of the fuel. Fueltreat BC 250 will do this. Following treatment, the water and dead fungus will drop to the bottom of the tank. It should then be drained off or sucked out with a hose, otherwise it will
sit on the bottom until becoming stirred up in rough water and again block filters. Treatment should continue for a few loads until filter operation has returned to normal. In an extreme case it may be necessary to empty and enter the tanks
to carry out manual cleaning
The cost of treating will depend on the biocide but can be estimated at about 1 to 3 cents per litre depending on the treat rate.
