Last year I had major problems with my FASS and our new ULSD (crap) when the temp. dipped below -10F. Years before, with even colder temps. and my FASS, I had NO trouble (using the same additive with LSD). Seems the oil companies/ additive companies didnt do their homework when it came to cold weather. The fuel is the only variable in my equation that changed. I took my factory fuel filter heater apart and checked the element, it works fine. I called several 1-800 numbers to talk to additive companys, most of which told me the same thing (with hard to treat fuel, double the dose, but dont add too much, it may drop out of suspension and plug filters. ). Great, now I need to be a chemist to use their product
So, this is what I am looking at (the kits on the right), but I dont know if it will fit the filter/head on my FASS.
Any ideas?
