Ford 6.7L Power Stroke Diesel :: 26 Gal Diesel Capacity - Can't Fill More Than 22.4 Gallons?
Dec 19, 2013
Keywords: Diesel fuel, tank capacity, 26 gallons, fuel tank, capacity, false advertisement.
On my 2012 F250 with 19k miles I have NEVER been able to fill tank with more than 22.4 gallons of diesel fuel. That was the day I ran out of diesel going to fill up thinking I had 26 gallons. Once the light comes on I'm filling up, I have every tank fill DOCUMENTED with (date/cost/gals/trip/$per gal).
Talked to local dealer Raleigh, NC , their explanation was fuel pickup was raised to prevent contaminates from getting into injectors. They advertise 26 gallons, should be able to access 26 gallons.

From all I can see, the fuel tank capacity on my '12 should be 17.5 gallons.
As I finish up a trip with it, I know I've "pushed the envelope" as far as fuel range is according to the guage/computer. I get the warning that I need to refuel and that I have 50 miles to empty, but I've driven 40 miles into that last range before refueling, and only been able to put 14 or so gallons into the tank.
My question is: If I were to drive until it literally runs out of gas, then fill it, would the guage/computer recalibrate or do I need to install a new fuel sensor?
I get the warning as the guage indicates just under 1/4 tank remaining, and I have yet to run it until the guage indicates that it's actually on empty (family and dog are with me so risking it is currently out). I'm hoping that the guage itself knows what the real deal is and that the computer is just not with it.... OH, FWIW full is EXACTLY on the "full" line and not over as in my Kia.

I was wanting to drain my trans pan and refill with new fluid. I was curious what the pan capacity is. With my 6.0 I did the drain and refill every 10,000-15,000 miles depending on how hard I worked it in those miles. It always drained out bright red and shifted like new until I had a T/C failure at 278,000 miles.

The 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 2012 got it's first "500 miles to empty...." DEF alarm yesterday. I added 2.5 gallons and the same alarm keeps showing up each time I start the engine. Is there some kind of other reset required? Do I need to fill the tank up completely to reset it? I'm concerned the engine will shut down after 500 miles even though the DEF tank is about 1/2 full.

I was draining my separator and noticed some oil accumulating on the bottom of the cylinder head right under the oil fill on the drivers side. My truck is 12 days out of engine warranty.
It's last service was probably around a year ago when the engine was torn down to replace the exhaust valves per the TSB.

I currently have the rear axle shafts off the truck. I took off, cleaned then put on the rear diff cover.
I live in an area that does nothing but form rust anywhere and everywhere in very little time.
I don't want rust forming in the rear diff gears - can I fill the rear diff up ? Or will it leak out of the rear shaft holes ? Can I fill it up halfway then ?

Started today. 2004 with 235k miles. Owned for last 10k miles. Engine was recently studded, has egr delete and ccv bypass. Runs and starts fine. New Ford oil cooler too. Checked for codes. None for misfires, perdel are reading 0.
If it sits, on start up clear exhaust, as it warms, more blue smoke. Smells like oil not diesel.
Researched before asking and found leaking turbo seals can cause this. So we pulled the intercooler tube in front of the engine going to the intake expecting to find oil residue. Nice and dry. Was this the correct one to look at?
When we got the truck we had the dealer do a relative compression test and was within limits, it did need 1 injector that we replaced. What would be the next logical place to look?
Couple more points:
- Just changed oil last week, checked today, it was slightly over full.
- Coolant is fresh and has not changed level since we got it.
- Pulled fuel filter to see if any oil, but it was nice and clean.

I filled up at the same fuel station I've filled up at for 6 months, never had a problem. I just bought a 6 liter and put some injector cleaner in on the last fill up. Ever since then, it's been running really rough and missing when cold, and even when it's warm if I really lay into it, it'll pop and sputter. The fuel in water lights been on since I bought it. I think I have a bad sensor, because it was running fine until I put that cleaner in. Since its been running rough I put in new fuel filters and drained the fuel water separator, which only had fuel in it. I don't really know what it could be, but I'm 99% sure it's an injector issue since it started only after I put fuel treatment in.

It only happens on a very Rare occasion.
When Cold, and when I start out as I open the throttle, it suddenly sounds like there is not a piece of quieting stuff on the engine. I mean its like I can hear right into the engine itself.
I back off, It goes away then I dont hear it again for another Month or two.

I've topped up the DEF and the warning is still showing that I'll have reduced engine power within 45kms.
Its weird, just yesterday it showed 550kms to empty so I added one full container, all day it kept showing less and less kms' til empty. Warning lights and bells etc.
This evening topped it completely and still shows. Is there a way to reset it without having to stop at the service dept.

Well, last night I took my F-350 up a wheeling trail. I'd been up quite a few times in my old Rover, so I knew I could go a ways in without damage. Just uphill, muddy, and ruts / rock steps.
One thing I notice is that when you engage low range in the diesel, the transmission starts in 2nd gear. My previous gas Super Duties always started in 1st. I'm assuming this is to protect the transfer case from torque overload. Also, the throttle response seems to change when low is engaged (the pedal becomes less responsive, which is nice).
I've had the gas Super Duties off road before, and all of mine have had the locking rear diff. The diesel lugged along perfectly. My biggest fear was crunching the DPF / SCR / DOC canister on a rock step. In that respect, I'd rather wheel a gas. The manual shift function makes a lot of sense in low range - you can force a start in 1st, 2nd, or 3rd. And prevent meaningless up / down shifts since the grade can change quickly.
These trucks' biggest hindrance is their size. However, if you have the trail room, they are actually excellent off road. Many people look at a Super Duty and see a vehicle good only for pulling or hauling. Not so, these trucks are as good as a Jeep off road, again with trail room being the only concern. The locking rear diff was never really needed, but I engaged and disengaged a few times to keep the mechanism free. I really love this feature.
One thing that happens frequently for me in north-east wheeling is water crossings. Could be a simple brook but mostly it is mud holes encountered on tight trails. In some cases these are only a foot or so deep; in other cases they are 4 feet deep. Ford states to "try" to keep the water below the level of the hubs, which amounts to about 15". Aside from possible front axle contamination, my biggest concern would be the electronics on the diesel which are mounted to the frame or floor pan (transmission module, NOx module, etc.) The gas Super Duties don't have these concerns. In the old days, as long as a diesel had air, the engine would run under water. This engine requires electronic control of many things, including the injectors...so it won't. There are also some axle / transmission breathers which run about floor pan high to be concerned about, but these can be easily extended.
Maybe it's due to the twisty frame which GM loves to insult Ford about, but these trucks have excellent wheel articulation. I'd be surprised if a coil sprung power wagon flexed more, at least in the rear. I'm impressed.
Finally, the traction control. I experimented a bit on a slippery rock step. This was the only step which required the rear locker - sort of. The front wheels climbed the step, but the back flexed to the point of one rear wheel basically almost off the ground and severely unloaded. With 4x4 Low engaged, and traction control "off" as much as Ford will allow, the truck could not pull itself up. Turning traction control on allowed the truck to very nearly pull itself up. A little more throttle / finesse probably would have gotten the truck over, but lots of ETC operation glazes the brakes and spews brake dust everywhere. Being able to start in a higher gear manually really adjusts the torque control. Locking the rear end and the loaded wheel bit right in and she went up and over.
When doing some off-road driving, the "off-road" screen for those of you with the LCD message center is kind of fun and informative to watch. It's nice to see how far your wheels are turned left or right when spinning in ruts or what crazy angle your truck is on. Howie Long could probably document the exact up / down / left / right slope angle a Super Duty needs to be on in order for the tailgate not to open. I never had an reason to open the tailgate while in these crazy angles, of course.
Overall, very impressed. It's not as good as my old Range Rover, but I would say more talented off road than ALL other Ford vehicles except the Raptor.

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.....

My truck threw a CEL after the first start today. The CTS reports it twice. I noticed it about two minutes after start.
P02E1 - Diesel Intake Air Flow Control Performance
The air box gauge is green and it doesn't reset when I push it so that appears to be fine.
The one thing I can easily notice is the sound of the turbo. Typically when I stop and park, the turbo spools up, then down, then spools again and gives a sigh of relief and it's then silent. It's not doing that currently.
Now, I can hear it constantly when parked and it spools down after I turn off the engine, even two minutes later. That is not normal for my truck when I wait for the above to finish its routine. When I start the truck, the turbo immediately spools to where I can hear it which is also not normal, as if it's building 0.5 psi. I realize that's funny to say on a turbo diesel but I know the sounds of my truck. The EGT's are fine, EOT, ECT, TFT are fine and I can build boost when driving without issue. I took the drive to work easy this morning so the highest I noticed was 10 psi.
I restarted the truck after a 20 minute drive to the office and it didn't clear the CEL. The CTS squawked four times when it woke up the second time but it didn't show me which PID it was upset about.
I'm thinking this has nothing to do with the CAI and this is something downstream of there. EGR related? I haven't opened the air box yet, at work and in dress clothes so that'll need to wait. My past four or five regenerations all started between 1.94 and 1.97 soot gpl. That is also not normal and is something I have been keeping my eyes on. Currently the DPF is at 2.10 so it has made it further. Normal behavior (post emissions flash) is above 2.54 soot gpl for an AR.

2007 6.0 6 speed, 187,000 miles. The other day started truck, had been running about 20 minutes before. Started fine, go to drive, chugging white smoke, smelled like unburnt diesel, baby truck home, seemed to run ok at low rpm, truck warmed up and ran fine. But I also noticed turbo boost was acting funny. Truck ran fine next few days. Then this morning, started cold fine, started to drive it and same chugging white smoke, it quit by the time j got to the end of my driveway, but drove to work, it quit smoking, ran pretty smooth, but will not build any boost. Truck is bone stock except for exhaust, it's straight piped. Ok. So this eve I borrowed my dads edge cts, here's all the engine codes:
P0069
P0269
P0299
P2262
P2269
The last one is water in fuel, since it started this crap I did notice it was right after it came on in the dash. I'm trying to figure out where to start....
On another note. VGT duty shows 85% at idle ?
Ficm voltage is constant 48 volts

Wtf is going on, Temps are all good, no check engine codes...bad diesel fuel? I had 1/4 tank of diesel fuel when I filled it up...

When the truck shifts into 5th gear i instantly feel a constant vibration and noise until it shifts to 6th gear. This happens nearly every time while driving at 40mph. Rpm range 1200 - 2000. I bought the truck new on June 30th and noticed the problem on my way to work on Monday July 2nd. Took it to the dealer on July 5th and the tech said it was the torque converter slipping. I drove it home because they didn't have time to work on it. Took it back on July 12th and the dealer has had it since (currently 30 days) They originally told me it was not the engine or transmission and it was an exhaust problem. Last week they said it was the motor mounts and said they would be done.

One of the great things I liked about the new 6.7L engine was the lack of any diesel smell. While the tips of the exhaust pipes remain clean at 64,000+ miles, no soot, my truck now has a strong smell of diesel after each use. The truck is running strong but I can't figure out why this is happening.

What is the consensus on this setup? Is it worth the money? Or is it more hype than function? Their logic behind it definitely seems to make sense.

On the way in to work this morning, I get the "Cleaning Exhaust Filter" message. This was great because I still had about 15 minutes of driving left and it usually comes on right when I am pulling into my driveway. As soon as the regen starts, I can smell diesel exhaust/fumes in the cab (this is going 70 mph on the freeway). When the regen was done, the smell went away. Is this normal? I could understand if I was sitting still getting some exhaust in the cab, but moving at full speed everything should be blowing away. This is my 4th or 5th regen and the first time I have noticed it.

What it is or why there is a three inch pull handle hanging down on the bottom of the Diesel Tank on my niece new 2012 F350??? It is sitting hanging there begging to be snagged and ripped off the bottom of the tank!!!!! I'm at least going to Gorilla Tape it up to the bottom of the Tank.
