Anyone have any of theirs go out? I was hauling my new Travel Trailer and suddenly I felt hard jerking movement, loss of power when I hit the gas pedal and stumbling. I pulled over, and it just struggles to start.. runs like crap and then dies. Finally I had it towed (and a good buddy came and got my travel trailer). The truck is a 3.5 Ecoboost, near 80k miles 2016 year. I was so bummed about seeing this trucked get towed. I am wondering if anyone else had a fuel pump issue. I checked fuse 27 its fine. Today it cranks over fine, but does not start. I even tried the remote start but only beeps. I thought maybe a fuel filter as well but I heard they are not replaceable and are located in the gas tank.

 

Not on this one but have on my previous f150 (10th gen). I dunno if dropping the tank is feasible vs moving the bed like on past ones, but they seem to continue the same general pump/sender style with the hanger over time. If that’s still the case, you shouldn’t need to spend $100+ on a whole new hanger assembly, when you can change the pump itself on your existing hanger for like $20 and literally a few extra minutes/couple of additional steps. I’d keep that in mind if your doing it yourself and don’t want to spend needless extra money.

 

My father's 2014 5.0 dropped a fuel pump a year or two ago. Cruising down the road at ~50mph, stumbled, died, refused to crank. Fuel pump gone.

Do you often run your truck down below 1/4 tank of fuel?

 

I mean sometimes I do. Not a whole lot often. I put regular gas and I do drive it a lot! I use it for business... I run a sign company and I have to often carry sheets of acrylic, mdf, pvc, etc. Taking it to a mechanic shortly. I a bit disappointed its not that old and the milage isn't too out there for this to fail. I was hauling a Camper Trailer... it was a bit to get both back home.

 

Very unusual, I haven't heard of that on these trucks. I did have a '98 Chevy Z71 and those things were notorious for eating fuel pumps and for having LOUD fuel pumps. I had to change the fuel filter every 10k miles or so just to keep it alive.

 

Does anybody know if this is the same thing as the TSB that is a known issue during towing? I can't remember all the details, I think the problem is that it runs lean and may stall and throw a lean code which sounds different than what you are saying. Worth the question at least....

 

That TSB only applied to 2.7Ls

 

Funny as it may sound, the fuel pump relies on the gas for cooling. When you start running down belong a quarter tank, the pump gets exposed to the air and heats up, leading to premature failure. If you often run it down, start considering 1/4 tank as your "empty" level.

 

I'd like to shed a little light on the 1/4 tank myth. Like almost all fuel pumps, the fuel pump itself is located inside a fuel pump "module" or "assembly" if you will. What this means is that the fuel pump is contained in a plastic housing and this housing is generally FULL of fuel even when the tank only has a few gallons in it. Fuel pumps do not overheat from running on low fuel levels. In theory a fuel pump could overheat if it ran with NO fuel but this generally doesn't happen since most don't continually try and run their vehicles with zero gas in it....

 

Seconding D2A... also fuel is running through the pump any time the engine is running, which is the only time the pump is running. The "below 1/4 tank" is a myth with no hard evidence to support it.
