When introduced into the system they can clog fuel filters and injectors, just like gunk in a car engine. Now, microorganisms are introduced via water condensation in the fuel lines, which promotes bacteria and fungi. They feed on the fuel. They can form colonies that clog the lines as well.”
“But I presume you have protocols in place that would prevent those pr
