Well just went out to start truck and it started and run about 30 or 45 seconds and quits with water in fuel warning on EVAC. Seams the other day after a couple hours out in very hot weather (Heat Index was 100+ all week) I had one last chore to due before going into house and the shower, add the 2.5gal of DEF to the tank.. Started to pass but thought I needed to get it out of truck bed and decided to put it in the tank.....well it seems in my heat addled state this 70 year old decided for his birthday next week to pour the crap in fuel tank instead. 
Somewhat lucky to have new fuel filter, unlucky to be unable to due the work myself due to old back and shoulder injury, not to mention the heat and having had 3 heatstroke's with last one taking 3 years to really get back to normal, So it's a tow 30 miles into dealer having fuel tank drained. Bet by time I get done it'll cost me a $1000 for the 2 minutes of stupidity not waiting till next day when I felt better.
