EXCUSE ME, I'm not throwing anyone under the bus so calm down. And I haven't been lucky. The odds are my way (and the way 99% of buyers who don't come on this forum) is many times more likely to be just fine. Yes, there is a microscopic chance that playing the nervous game may save you, but I'm not going to live that way. You could just stay home and not drive your truck ever and that would increase your odds even more of never having a problem. Perhaps you should consider that.

I use the 1/4 tank rule as well, and finally got my wife to do the same. How I got her to adopt it is if there is an emergency and we need to get somewhere, or get someone to the hospital etc, we sure don't need to stop for fuel first.
In the Marines, if someone runs a diesel vehicle empty, it's a page 11 entry or even office hours (both disciplinary actions). I know crap happens, but it wasn't allowed in the Marines ROR.

I got to 24 MTE last month accidentally and thought I would be starting this thread. I wrote it in my head several times to amuse myself while I was sh***ing my pants watching the MTE counter number diminish while pulling my fifth wheel on the Pennsylvania Turnpike. I ALWAYS start looking for fuel around the 100 MTE mark. There were no fueling stations from that point to when I needed to empty my drawers. That fueling station rose in the distance like a Phoenix from the ashes.
Other thing that kept me sane was a buddy saying that even though the MTE reads 0, there is still approximately 50 miles worth of fuel left... half of that when you're towing.

And there have been a few times that I have sat out in the middle of no where due to a traffic accident or construction for over an hour being very happy to have that quarter tank buffer there.

It would be my luck that I would run it low on fuel and have just enough to pull into the next pitstop on fumes - then a Regen cycle would hit and it would be like flushing a fuel toilet...

That is one good reason to have an OBD gauge to monitor regen status. I don't advocate pushing the limits of fuel capacity, but a regen would certainly throw a monkey wrench into your plans. I try to pay close attention to how far I am away from fuel especially when traveling at night.

I must be the luckiest guy alive because on every forum I'm involved in, trucks, suv's, cars, boats, rv's, atvs, snowmobiles, tractors, etc. etc. there is a pet issue or two that people are terrified of. There is always a "known preventative measure" for every one and I've never done one of them. Never EVER and I've never had the "known issue." Guess I must knock on wood really well.... Or more logically, the odds of the issue are so microscopic that I'd be more likely to get hit by a drunken driver or perhaps lightning than having it happen. The reason these things take on a life of their own is because good news dies a quick death and bad news travels fast and lasts forever on the internet.
PS: I also don't wear a seat belt, don't wear a helmet when I ride, don't buy extended warranties, eat a poor diet, and drink at will. Guess I'm a real rebel.... LOL And, if any one of the vast warning's I ignore finally catch up with me, at least I lived a free and unrestricted life. This isn't practice. You only go this way once..........

I don't think running dry once will cause any measurable harm to the fuel system. The instant air enters the HPFP system pressure will go down dramatically. These things are designed to pump fuel that doesn't compress nearly as much as air.
Of course shortly after fuel enters the system the engine shuts itself down. I really don't think you hurt anything here, but I wouldn't advocate testing that theory.

It was at 0 MTE but I'm not sure how long because clearly I wasn't paying close enough attention. I got a "Low Fuel Pressure" warning, followed by "Reduced Engine Power" about 2 seconds before it died.
Filling up, it took 36.1 gallons total. So I don't see how Ford's 37.5 gallon claim can be true, unless they're counting unusable fuel in the tank.
Big-foot, not sure if you're aware, but our trucks don't have an in-tank fuel pump. The low pressure pump is in the DFCM.
Thanks all for the advice and recommendations!

I typically fill up at 1/4 a tank as well. However, there are times where I've ended up under that for whatever reason, breaking the rule and it happens.
Tom, do you know if there is air detection at the LPFP?
It seems, from my non-engineer chair, beginning "safe mode" would be best when there is lack of fuel there, that way the HPFP isn't affected as badly.

It's not air detection per se, but a pressure switch that detects low fuel pressure going into the HPFP. Once this switch is closed the truck enters this "safe mode" to limit damage.
