Fire issue 2017-19 diesels
Does anyone know for sure what the culprit or issue has been with the 2017-19 6.7 catching on fire ? Seems the majority have started in the engine compartment and it looks like most have started on the drivers side. Small fitting (return) on the secondary filter breaking off perhaps ? As many diesel trucks in this year range that have caught fire I would think this would have been a safety issue enough for a recall of some kind for a fix.

How many have caught fire? I've only seen mention of a few. There is a problem with the engine mounted fuel filter. They sometimes spring a leak and spray deisel all over. There is a recall on them but only a limited year range, not 17-19. I have heard it blamed on lack of maintenance, as in not replacing them soon enough....I don't buy that. I think Ford should take a look at how they can beef it up, IMO a fuel filter should never burst no matter how many miles are on it.

4wd6.7L - if you search for a 6.7L engine thru any of the salvage yard venues, you can see a lot have had fires besides the normal carnage from close encounters with all sorts of items.
Seeing a lot that have had fires got me a little concerned so this is why I'm asking. If nothing else maybe do some preventive measures to head off such an issue. My first act will be to purchase a good fire extinguisher to carry. It's a good idea to have one anyhow, right ? Never thought of this before until seeing the end results of not having one. Guess they call that hind sight !

yes, the return fitting on the engine bay fuel filter breaks as well as cracks in the plastic fuel filter housing.
they come out with a clam shell protector for the fitting.
dont know what they did about the cracks in the plastic housing.
diesel normally does not flash at atmospheric pressure so more needs to be understood on why some flash and some dont. perhaps gas in the diesel.
my hose popped off once. no fire. but fuel every where.
I installed the new clam shell connector and used a squeeze clamp on the hose.

If mine catches fire, I will let it burn. No way would I want them to try and fix that. While some may have had issues with a fuel filter, how many others are self-inflicted by rigging up wiring to add accessories with folks that have no idea what they are doing.

There is a retrofit part to address it.
There is probably little to no old parts left to install.
My 2020 is a new design and I think 19 is too.

I lost that filter fitting on my 2016 just as I crested Washington pass in the North Cascades in Washington . We had just completed a long steep climb pulling the 5th wheel out of Winthrop. Diesel fuel all over the engine and ground. No fire , good thing as we were miles from civilization of any kind.
