This is what I saw today at WestMarine

This is not the tank cleaner, although they had that too. Have you tried this additive as well. It looks awesome.
I get plugged filters often and need to find out why. I went through previous owners receipts and found my tank was dropped and cleaned at a radiaitor shop a few years back. My tank screeen is clean as of last weekend...but today after running 150 miles on 80/20 blend- with no water in it-and double filtered- 1 week settled WVO-; I still had to change out both filters because of a loss of power.....WTF?
Especially the paragraph on "Treating water in fuel".
