I was reading up on the DPF, and this is the part that kills the alternative fuel option. B20 would be max for the 7.3L with the "upgraded" emission technology of today.
Water intrusion in the fuel my ****. I have a clear housing on my pre-filter, I rebuilt my fuel bowl three years ago, and I checked the bottom of my fuel tank when I did the Hutch mod. With all that, I found 2 or 3 droplets
of water in the bottom of the tank.
Maybe the "water" intrusion is their way of saying "Stop putting DEF in the fuel fill spout!"... maybe not.
- I put the question over there. [LINK
