I ran Biocide in my truck as a matter of habit when I had a clogging issue with my tank sock last year. Well, I ran out of Biocide about 2 months ago and didn't bother to rush and go get more. Well the truck has been fuel starving the last week or so and I had to keep filling the fuel manager under the hood every once in a while. Come to find out the screen in my walbro lift pump was clogged. This is with a CAT 1R-0749 pre-filter so my guess is the brown slime was something that was Biological in nature. Biocide is cheap guys and can save you some serious agravation if you use WVO or blend WVO into diesel.
