Interesting TSB... Be careful where you put that DEF fluid.... There also looks to be a condition where they are replacing all eight injectors....

Very informative, thanks for posting.

Added to tech folder!

 

Thanks for the good info.

 

Good to know and now all the more reason to keep spare filters on hand.

 

There must have been quite a few people putting DEF in the fuel tank to put out TSB.

 

I don't know about that. I don't think it would take many $10K repair bills due to customer negligence for Ford to wise up to the problem.

Stuff like this is great for people to know though. Knowledge of the damage DEF can cause just saved 6.7Fan a LOT of money!
