Purchased 2011 3 weeks ago. Due to not paying attention, put gas in diesel. Had tank dropped and drained but after reassembly, fuel gauge inop. When turn ignition switch on, get normal sweep of all dash gauges but fuel gauge does not read. 2nd tech says sender okay, must be gauge. Dealer ssays if it sweeps, it isn't the gauge. 011 F250 6.7L.....
View 7 RepliesI just got a 03 f250 cc lariat with the 6.0, the truck sat for a month and a half before I picked it up, I got in started and the fuel gauge showed over half and the miles to empty was accurate and the temp was as well, about half way home the gauge dropped below empty and the fuel light turned on, then the miles to empty went up to 455 and the temp showed 67 when it was 92 out. I have read other post with these problems but no one has a solution, people have recommended techron for the fuel sender, but techron is not recommended for diesel...

Wife drove the truck before me and bunched the floor mat under the pedals. I didn't notice the mat issue when I drove the truck today. I accelerated fully after doing a left turn onto a busy highway. The motor spun up hard with the accelerator floored but because of the mats, the pedal stuck all the way down. I was approaching stopped traffic while under full acceleration and I shut the engine off and pulled over to the shoulder all while braking hard ( it was a hell of a ride!). I freed the pedal and restarted the engine.
Now, despite a bit less than 1/2 tank of fuel (I have the 38 gal tank), the dash readout was showing "Low Fuel", the gas gauge was below E and the engine was running like it was running out of fuel. I turned the engine off again and left it off for 1/2 hour before restarting it but the gauge and engine still behaved the same. As I drove to the nearest diesel station, the engine was not running "right". Of course the station I pulled into had 1 diesel pump and the pump was broken.
Because I thought I might actually be out of fuel, an understanding stranger took me to the store to buy some gas cans and then to another station to get 6 gallons of fuel. I got back to the truck and added the 6 gallons of fuel. When I turned the key on, the fuel gauge immediately came up to 1/2 tank. I then drove to that other station and added another 15 gallons of fuel to fill it. This confirmed that I had about 18 gallons of fuel in truck when the "Low fuel" warning occurred.
So, what the heck was going on with the fuel gauge? I am sure the "Low Fuel" warning is tied directly to the gauge but why was the gauge reading low? Is it possible that the "Key-off" while under full acceleration followed by hard braking had confused the ECU? I am just trying to figure out if I have a fuel sender problem or a confused computer that corrected itself. Until this incident, the fuel gauge has never been a problem but the wife messing up the mats has been an issue!
For the second time in 6 weeks My 2004 F250 Powerstroke has run out of fuel with the gauge showing a 1/4 tank. First time it was just under a 1/4 showing I had it towed to dealer and they told me it had sucked in the filters requiring replace and flush of system. The told me that this happening very often and I would be replacing all of the injectors at my cost. I told them that I didn't want this to happen again and to check out the fuel gauge and sending unit and replace if in doubt. Well they checked it out and found nothing wrong, told me it was accurate and should not be an issue again. Now 6 weeks later on the Friday night before a holiday, it did it again, this time with over a 1/4 tank showing. I really don't want to spend 6 grand replacing injectors and would really like to trust my truck again, getting to the point that I'm nervous at 1/2 tank.
View 9 RepliesI just recently bought a 2011 powerstroke f250 and while running I can hear the fuel pump humming pretty loud. Is this a possibility that it's going out? Or is this normal?
View 3 RepliesWe got "bad" gas in Feb, 2016, had to replace entire fuel system. Haven't driven the truck but 4000 miles. Last week, she started spitting and sputtering and lost power. We could see fuel pouring out. NO CEL. Towed (AAA has paid for itself several times over with this truck) to dealer that replaced the fuel system, still waiting to hear from them. Does this sound like it should be under the warranty for the work they did? We have averaged a huge repair bill about every 3-4 months on this truck, 2011 F250 Lariat, 8cyl, 6.7L, since we bought it 2 years ago.
View 1 RepliesRecently my 2011 F-250 Diesel with 21,000 miles seemed to start hard one morning. After starting the truck it ran well that day and started fine. The next morning it would not start. Had it taken to the dealer and they went to work. Started at the fuel filters and replaced low pressure fuel pump. Thought a piece of the defective pump had moved up fuel line. Removed high pressure pump and found signs of rust. All regular service intervals have been met. Didn't see this coming. No water in fuel light or other warning.
View 14 RepliesI have my aux fuel tank pump hooked to upfitter 3. It has worked perfectly until this week. I started to transfer fuel and the aux fuel gauge and fuel pump both quit. The led on upfitter switch 3 still illuminates, but no fuel pump. I found fuse 9 on passengers kick panel is for upfitter 3. The fuse was good. Is there another fuse somewhere for the circuit I've missed? I can trouble shoot the wiring if necessary, but it's tough to do all behind the left side underbed box and not easy to get to. I've missed something simple before I go further????
View 14 RepliesRecently my fuel gauge malfunctioned. It wouldn't register fuel in tank. When I filled tank a couple times gauge worked but as soon as a gallon was used it would drop off. Now gauge not working and wrench appears code flash 246c and check engine light on says reduced engine power and says drive to clean exhausts emissions. No miles to empty registered as it reads --- miles to empty.. Also... What's this about egr replacement and should I contact Ford for this as I had no notification.? I have 2011 f250 SD 6.7
View 14 RepliesMy 2005 is doing strange things. The fuel gauge is always incorrect. I have done the following:
1. Replaced fuel level sensor.
2. Inspected and tested wiring from the firewall to the tank.
There are no codes present and the fuel % listed in torque is always correct. The gauge sometimes reads 1/2 above full, nearly all of the time it's above the 3/4 tank mark. I have an android head unit that I am using to gauge fuel level right now. I believe the cluster is bad.
I just had headgaskets (oem) studs, egr delete,oil cooler done on my 06 plus water pump cause the gasket blew. I have a sct livewire hooked up monitoring everything and tonight i noticed that the eot and ect's were way off. fully warmed up and rolling 65 Anywhere from 40*-50* out it was eot-156 and ect-172. Degas bottle was at the normal level.
I am also having issues with the fuel gauge. Every now and then the gauge will go to E and the miles to E will display ---. Turn the truck off and back on it works again. I am half assuming its the plug on the sending unit or the sending unit itself.
I finally received all the parts needed for installing my fuel pressure gauge, but I am wondering if I am going to need a schrader valve on my fuel pressure line going to the sending unit, or if I am going to be safe with just doing a 6 time cycle of the fuel pump like we do when we change out the fuel filters. Seems like that should work for getting the air out of the fuel lines, same concept I would think.
View 14 RepliesWorking on a 2015 f-550 with a 6.7 power stroke. Damaged the wiring harness and fuel gauge not working now. Where could I find a wiring diagram? The low fuel is now causing it to not regen. We have continuity through the wires and they have been repaired but gauge still does not work. Currently now power to fuel gauge sender?
View 1 RepliesI've recently brought her back to life after a couple months of delayed loving due unforeseen reasons. And now the fuel gauge is completely under the E marking! I'm fairly smart and have looked some things up from other forums just trying to get a one on one response of that makes sense. "If were in the military you will understand" please break it down Barney style!! Not saying I'm dumb just want a good understanding
View 10 RepliesWell, I was cruising down the highway @70MPH and notice the fuel pressure gauge dropped down to 50 then back to 65. Kept watching the gauge and it would swing back and forth from 55 to 65.
Got off the highway. Nailed it at the light and watched the gauge drop to 53 and swing back to 65. Fuel pressure is not steady either. It swings back and forth from 52 to 65. Thinking the pump is on its her last legs? Truck got 194K on her.
Couple of years ago I installed a fuel pressure gauge. I wrapped the fittings with teflon tape. Well within about a year it started leaking. So I shopped around and used Permatex Permashield fuel resistant sealant on the fittings. It says diesel resistant on the package. Couple months later leaking again. So I take it apart again, clean every fitting and follow the instructions to the letter. Well its leaking again. What will resist diesel fuel under 55 psi pressure. All the fittings seem to be pipe thread.
View 7 Repliesfuel gauge does what it wants? It goes down to half way then goes back to full or sometimes even empty. Not a big deal for me because I have gotten used to it. But I would hate to have my wife in here and she thinks it's good and run out.
View 14 RepliesThe installation of the new 50 gal. Titan tank went well overall. Start up was smooth with no leaks but the fuel gauge is showing empty with about 45 gallons in the tank.
The sending unit was properly oriented ("clocked") so I'm guessing the electrical connector is not secure at the top of the sending unit. Not sure I can reach the connector without lowering the tank somewhat.
My fuel gauge acted pretty weird today. When I left my house today it was just above half a tank. I was sitting in traffic quite a bit and then looked down and it was below the e. I knew it wasn't empty so I kept going. Got to work. Went for lunch and it said full drove about 5 mins to eat and it went down to half a tank. What's going on? I am thinking of the fuel sender or wiring?
View 3 RepliesOK so 2006 f550 6.0
If I want to monitor fuel pressure with a gauge in cab while running all the time... (not just testing) can I purchase one of the secondary fuel filter caps that have a port in the top and connect the sensor to this to run or is there a better way? (Or is that not going to work)
Cap I am talking about is something like this

(I know this is a combo kit but they do sell the fuel only) But since it has a threaded port in the top I could connect the fuel pressure sensor to that and go from there correct? Would that give accurate readings?
Fuel gauge goes back to empty when I fill the truck all the way up. It goes back to full once I have used up 2 gallons ( from 36 gal to 34 ) on my 2012 F350. I also had a similar issues years ago with my 2003 6.0L .....
