I'm with Kevin. I just went through this a few months ago. It turned out that I had about 3 foot of incompatible fuel line in my system. Made my filters black but did not have dark grey residue coming of the element as we can see on your fingers.
Is it possible that when you filled up, the gas station's tank was low or something? and maybe you picked up a bunch of sediment that gathered on the bottom of their tank? I'm out of guesses if it's not that.
Are all your fuel lines from Lethal? If not I would check those first. When you check, the inside of the fuel line will be breaking down. What I did to test was to look at the inside of the line while it was wet with E85. Rub the inside of the line with your fingers and you will see the residual fuel on the inside of the line turn black. When it dries on your hands, it will leave black residue. I hope this helped in some way. Good luck.
