IDK man. We'll see. He said that the new update is too big for some of the units installed pre 2018 or something along those lines and so the unit cant handle it and crashes.
I had the same issue trying to update my Sync system. I found that if you download the update to a USB and split it into two parts it will work. IIRC it has to do with the way that it writes/deletes and the ordering of it. Basically it tries to install before removing older components of Sync and then it runs out of room for it. Basically put the step 1 (removal) components on the flashdrive, run it. When it is done, power cycle the truck and then run the step2 (install 3.0). I don't have the Nav component for my radio and Ford designed the updates for that system, which has larger memory capabilities. The attached PDF shows the file breakdown. I think it was on F150forum.com that I found the info on how to do it.
Can't imagine what fuel service is, my last two Chevy's don't even have fuel filters anymore.
I have one on my truck. I dump it out every time I do an oil change, and it usually has a bit of gunk but nothing that wouldn't otherwise be fine getting recirculated into the engine. I would say because our trucks are naturally aspirated, it really just comes down to wanting one or not. If you had an ecoboost or supercharged F150 it would be another story all together.
