Ford 6.7L Power Stroke Diesel :: 2015 - Rubber Air Inlet Into DEF Tank?
Jun 17, 2016
I was filling my DEF tank (2015 Super Duty 6.7) with 2.5 gal jug a few weeks ago and while I was filling it, the small black rubber air inlet on the container that allows air into the container while filling my truck got sucked into the container and then straight down into my DEF tank before I had a chance to stop the flow. Is there a screen in the DEF fill hose to catch foreign objects like is in the gas/diesel fill hoses?

The DEF low caution is on and counting down the miles to go but the DEF tank is full. The caution goes away for a start or two then comes back. She's a 2015 F250 with the 6.7L. I love this truck but its starting to really bug me. I don't know if its related but she's been in the shop four times for warranty repairs to the wiring harness in the past couple months. Apparently there were loose connections in a couple of cannon plugs that the've now bypassed which were causing loss of communication between computers...

I recently bought a used 2015 F250. When the fuel level reached 1/4 tank it became hard to start. Sometimes up to 6 seconds of cranking to get it to start. I filled it up with fresh diesel and it fired up as soon as I turned the key. A week later the problem returned, this time I was above 1/2 tank. I run the recommended additives, I changed both fuel filters, but it didn't work. I have only had the truck 3 weeks, and it still has a warranty. There are no fault codes, and the truck run great once started. What could be wrong.

My old pipe to the heater core coming off the front cover was frozen in place, and long story short, the flange where the tube goes in with the o-ring broke.
I found part number 3C3Z-6608-B, which is the Motorcraft Front Cover kit and includes the LPOP and water pump, gaskets, seals, etc.
Another few hundred bucks and more time I don't have, but is that the right part? Is it possible to just get the cover? Considering the age of the motor, I'm OK with replacing all these parts, but money is getting a little thin at this point.

Left work tonight in heavy snow fall. Was in four wheel drive and following some slow pokes, till I could finally pass. I thought the smell was the cars ahead of me. Got to my crash pad, (5th wheel home away from home) and noticed the smell seemed stronger in the cab. Checked under hood and is not from the engine. Cab stinks bad.

I am doing the usual upgrades on a 2005 F250. What started as a small leak at the rubber coupling between egr tube and oil cooler turned into doing everything else while motor is down this far.
I am curious what the difference in the upgraded oil cooler is? Well besides not prone to failing as early.

So I have just over 14k on my 2015....... I love the truck but have had a few small issues. I had a water leak coming in from the roof that would leak through the grab handle. Nothing major dealer replaced one clearance light seal and they said the windshield needs to be re sealed.
Then I had a god awful irritating squeak in the dash..... It only does it late In the day when it's been hot. The dealer said it was a loose air bag. I have had the truck back a week and it's doing it again.
Those are little issues that will get resolved...... I hate having problems with a brand new vehicle but I understand it happens and that's what warranty is for.
I also reported a bad shake to the dealer...... The truck will shake very violently and have a very loud "diesel" sound. It's very specific at when it occurs. It has only done 4 times in the past 6 weeks including today. The odd thing is the 4 times it has done it has been the same time of day in the exact same spot on the exact same road!!!!
Basically I leave my office sit in some traffic and by the time I get to the parkway it has been35 minutes or so. Only happens in 6th at 60 which is roughly 1,400rpm a slight load due to a small incline and it shakes real bad! The typical "diesel" sound you get when under a load is very pronounced almost to a knock. It will continue to do this as you slowly increase throttle until it down shifts and then goes away. I also caught it doing it and I manually shifted to 5th and it went away.
Because of the rpm at which it happens with slight load only doing it in 6th I lean to a Trans issue and more so a converter problem. It feels like converter shutter. I just don't understand the engine sound.
I gave very descriptive info to the dealer..... Several techs drove it and could not duplicate. I just picked the truck back up last Thursday and the dash squeak is back and the shake happened yesterday and again today. So I am a bit irritated to say the least.
I really hate the fact that I know there is a problem but I also understand if a tech can't duplicate it he can't diagnose it. However today I did get a video of it with my phone so they will know I'm not making this crap up!

Looking for instructions, How to drop the DEF tank? I've loosened a few bolts, but still can't get my hand in to thread in the nut. I've already lost one nut, gotta pick up a replacement at the store tomorrow.

2012 6.7 .... Noticed my coolant level in the primary tank was low. Thought it was totally empty but it had about a half inch left in it. Topped it off and also needed about a quarter inch in the secondary. I would say about a half gallon between the two. Truck was at about 36k. Has 37.5 on it now and haven't noticed any loss. Never smelled anything, no signs of any leakage. Oil looks fine. Is this 'normal'? Owners manual says to check and add. Never had this with a gasser or any of my tractors over the past 30 years. This is my first light diesel.

When I fuel up and open the cap on the filler neck I always hear a hiss. Never could figure if it was pressure or vacuum. Today, after changing oil, I opened my fuel filter bleeder to check for water and it just started slurping and gurgling with no diesel coming out. I lowered the truck, removed the fuel tank filler cap and heard the hiss. Raised back up and opened the filter bleeder and diesel came out. I now know the hiss is a vacuum. Is this normal? If this tank is vented I have a problem somewhere.

1st diesel was a 1997 F350 dually (White Lightning). Upgraded last year to a 2015 F350 (The Rocket Sled)- the kids named it hahaha. Had to take the 6.7 (9200 miles) into the shop... Last Sunday I took the truck out and about 5 minutes from home I got the low fuel pressure warning. Pulled over and tried to purge air out of fuel system- the low pressure pump was making a terrible racket. Turned around and limped home- reduced power came on soon after. Parked it until I could get to the dealership on Tues. Long story short- dropped it off at the dealer (low pressure pump still making noise/ no low fuel waning, just CEL light).
Called to check status today- dealer can't seem to duplicate problem. Service advisor said if mechanic can't find anything wrong, service manager was going to take it out and try to duplicate. The is the 2nd time I've got the low fuel pressure warming. The first time (around 4000mi. ) was in winter- I changed out fuel filters and it went away. I was towing the 5th wheel. Just had to vent-I have to get this figured out. I wouldn't thing the filter could get clogged within 5k miles. Have a camping trip scheduled next week!!

I've had the Titan fuel tank installed for about a month now and am loving the extra range, although this morning I walked by the truck and got a slight whiff of diesel by the fuel filler door. I pulled out the flashlight to take a look, and noticed a really small, faint trail of diesel fuel running down the driver's side of the tank near the rear strap.
I crawled under the truck to inspect it as best as I could in the driveway, feeling around the sender, filler, and vent tube connections, and didn't notice any obvious puddles of diesel. About the most I got was some dampness around the sender unit seal, but it wasn't much, and could even be residue from the fuel lines dripping during installation of the tank. Based on where the trail down the side of the tank has formed, my best guess is it's going to be a filler or vent tube hose clamp that I didn't get tight enough.
Unfortunately I just filled the tank up last night and am headed out camping for the weekend this morning. I followed all the install instructions exactly, making sure to check the torque on the sender unit seal four times before installing the tank back in the truck because I didn't want to deal with any leaks, so I really hope it's not that seal. I also filled the tank up to the brim right after install and crawled all around it a day or so later and noticed no dampness or leaks. Needless to say, I'm not looking forward to dropping the tank again and then potentially waiting on parts if something is defective. I'm waiting on a call back from Titan to get their advice.
Below are a couple pics of the weepage. Obviously not a huge leak, but something I want to get taken care of ASAP.

The truck now makes a whining sound for about 30-40 seconds on a cold startup from the fuel tank and def tank area . what could this be ? Its at the dealer for other issues also , the dealer said that it was my starter making the noise, I'm pretty sure the starter is attached to the motor and not located by the fuel tank....

2005 F250 Superduty Crewcab 4x4 6.0L diesel/auto
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!

Why my subwoofer won't work? Dealer is stumped. Dealer changed out the speaker and amp. They have been waiting on the Ford Hot line for over a week to get a direction and nothing yet. The speaker does move ever so slightly on highest level.

Since I bought my F350 last Jan. I have several times had prolonged instances of a severe grinding noise coming from the front end, seemingly the left side. At slow speed in a turn (shallow or steep) a horrible grinding sound is apparent as well as a vibration in the steering wheel. At 9k miles a dealer said it was the wheel bearings and replaced both sides. I now have 12.5K and it is worse than ever. My local dealer says it is normal but that has to be bull. It is is worse after I drop my fiver after towing. It is a 4x2 with the 6.7 diesel. I love the performance but this front end issue is a real problem.
