I was supposed to stop and get something today, but where.....and what?

It's not a requirement from Ford, just a strong recommendation. Want to know more about what Ford teaches the tech's they will ONLY allow to do warranty work I suggest you go to one of their schools like I did.

Picture yourself sipping ice tea thru a straw on a hot day, now picture yourself doing the same thing in a meat locker, which way do you think you will get and stay cooler.

Can't make it any clearer than that.

Every new vehicle I have ever owned or been assigned has some sort of warning not to run the fuel too low, especially as the vehicle ages. Months and years of schmootz that finds it's way into the tank can end up causing problems in the fuel system. I learned the hard way on my 1985 Dodge Diplomat while investigating how far it would run after the yellow light came on. After they dropped the tank AND did a fuel system flush, I decided I'd keep my vehicles from running dry, or even risking it.

I can't say for sure if the danger is as great with modern vehicles, but I would rather not find out the hard way again!

Its true the fuel cools the pump. But the only vehicles I have ever heard of that needed fuel pump replacements were gmt800 trucks and suvs...every single one of those need(ed) fuel pumps at 60-100k...so every gm forum they go ham on saying you need fuel to cool the pump.

Its definitely not a good practice to run super low for sediment/cooling reasons but it won't kill you unless you run it down every single time.

This is what I have done on every vehicle I owned. Top to bottom, rinse, repeat. Never had a pump go on me and I let the fuel filter do its job. As if that sediment was going straight into your FI!

This whole business just reeks of old wives tales.

So...

Ford, having designed an apparent dysfunctional fuel system

...which is in millions of vehicles on the road...

...out of all those, which I can't for the life of me recall hearing an incidence...

...strongly recommended to owners not use 1/4 the fuel in their tanks?

Really?

Is that in the manual? Boy, they will have really set themselves up a class-action lawsuit if their system is flawed as such and it's not covered in the manual or at least not in ALL CAPS so we know it's really true.

Ok smartass, to put it in words YOU can understand it's like the recommendation to check the air in our tires so we don't have a wreck when it blows out from under inflation. We have pressure monitors to help us with that and fuel gauge for the other.

Comprehend?

I had to replace the fuel pump in my old Ranger, but it was from self inflicted, hard abuse.. I ran out the gas and stalled about 20 times in 15 years. I was pushing my luck like an idiot. Many of those were in very hot weather. It wasn't until the truck had 170k miles on it that the pump finally gave out. that's a pretty impressive pump.

Thanks for clearing that up!

Oh... wait, the tire pressure thing, like the oil level, tranny level, coolant level, brake fluid, heck- wiper fluid level... as well as tire life and brake pads, are all finite items with well covered consequences in the manual. Can you tell me what page the "Don't go past 1/4 tank" "recommendation" is on?

The fuel gauge's intention was to make the driver aware of gas level, so you know, cars don't litter the side of the road, not to signal the impending doom of the fuel pump.

Could have been coincidental, but the only fuel pumps ive ever had fail were both accidentally run dry a week or two before they crapped out, a Sierra and a cavalier.
