The only remedy, as far as I >know, is >to take the filter apart and clean the bowl by hand I don't consider 1 1/2 seasons a "very long time". especially since Diesel bought at the same time and stored in red plastic 5 Gal fuel containers was clean as a whistle. Main difference is that I added Biobor JF to the actual tank but nothing to the fuel in the plastic containers. I did clean the Racor bowl by hand and changed the filter (2 micron). Hence I repeat my earlier question: Has anybody else had this problem of sudge after using Biobor? George of Scaramouche, Lake Ontario P.s: My engine runs fine - no sludge ever got past the Racor!
