Pay attention to petrol stations. The petroleum delivery trucks connects their hoses to the pipes that are near the ground and stores the fuel underground, not all petrol stations are squeaky clean like clean rooms. Can't be helped if contaminants do get it. Most petrol stations I see do have loose sand/earth on the ground.
Physical debris such as silica would probably sit on the bottom of the tank, but imagine if the delivery truck is delivery fuel to the underground tanks, gushing the sediments from the bottom while you're pumping fuel at the same.
Silica is only one example that I can think of, I don't know what other contaminants are there, I'm not an expert. I just know I don't want this stuff going to my fuel injectors. Looking at the simple demo, I do believe it works, and displacing water is good, my question is simply what happens to the contaminants such as silica? Telling me low chance of occurring doesn't explain what happens to it when mixed with fuel and this fuel system cleaner.
