Just for information. On gasoline engines the fuel membrane will suck fuel in preference to water until the entire surface area is exposed to water. When only water is left the engine will starve of fuel and shut down. This was tested for in tank fuel socks on fuel sender pick ups. Do not know if this is true for diesels.
How prevalent is water in fuel? I for one have never ( knock wood ) had a drop of water in 106,000 miles from diesel fuel purchased all over the USA/Canada including Alaska?
Think you are talking of a water blocker membrane.
That is standard equipment / off the shelf available for most diesel filters.
But Ford did not specify a filter with a water blocking membrane for the 6.7
I have drained my fuel / water separator every 8,000miles or so --- found not a drop of water in it.
But evidence of rust like brown deposits on the tank filler suggest there is something in it in the tank.
