I am in the fuel business and operate a underground bulk plant.I mentioned in my post that no one at the FBO could explain where the bubbles came from. What I didn't mention is that they were emphatic that it *couldn't* be water... because of the water detection/separator system.
Yet, of course, it was. Turns out that the detector system had half-way worked...it was supposed to shut down the fuel flow, but it only reduced the rate. I remember when I was filling the 150's tanks I was saying, "Jeeze, this is slow...."

My airport sticks the underground tanks every morning and uses water paste on the gauge stick. It will indicate water. Then they compare the stick readings to the veeder root print out. Never trust any electronic water detection/auto eliminators. Good old water paste is still the best way to detect water in fuel.
Wish every operator would do that on a daily basis.
IMO if I found that much water in my sample cup, there is no way I am pouring any of that fuel that back into my planes fuel tanks. I don’t care what kind of filter you have.
