Ford 6.0L Power Stroke Diesel :: 2003 F250 - How Auxiliary Fuel Tank Works
Mar 17, 2015
I recently purchased a 2003 F250 Super Duty with a 6.0L Powerstroke Diesel. The truck came with an auxiliary fuel tank in the bed, but how it works. There is a keyed switch in the cab next to another regular switch, and I have not had the courage to try either of them yet since the whole thing looks like a DIY job. I did look under the truck, and can see what appears to be some sort of solenoid setup.
Just wondering, how it works and if it is safe to operate. I do not see any rollover valve, and want to make sure I do not overfill the tank if I use it.

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.

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.

I have a 2006 F250 c/c LB and I am curious, how much fuel is left in the tank when the low fuel light comes on?

I 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...

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.

So my 7.3 started sputtering and lost power, died on the side of the road. I wasn't far from home put about 8 gallon of diesel in the tank with a couple of fuel jugs and it fired right up.
Gauge was reading 1/8 of a tank and low fuel light did not come on. (low fuel light comes on when you start) Gauge came up to about 1/2 after putting fuel in.
What happened? Gauge was always reliable and low fuel light always did work. Only work done to fuel system was had new tank straps put on a couple of months ago.

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.

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....

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...

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 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?

I've been MIA for a while. 2006 F250 just hit 83k miles. My coolant must be puking out of the degas tank. White residue all over degas and drivers side engine bay. I had my mechanic buddy pressure test coolant system for several hours and he said there weren't any leaks. He told me to replace the degas cap for now. Didn't solve the problem. Temps have always been fine. Never found drops or a puddle of coolant. Even when the truck has sat overnight for over 8 hours, there is still a bunch of pressure built up when cap is removed.

I am scheduled to leave on a trip in the morning. I have installed an 85 gallon in bed auxillary fuel tank. I plumbed it in as per the instructions and the same as the last two I had in other trucks. After install I pumped 25 gallons in the aux to see how it worked. Every thing worked right. So yesterday I filled both tanks to the top and left the shutoff between them open.
This morning I noticed a puddle of diesel on the shop floor. Wiped it up and left for the golf course. Got home and found another puddle. I have closed the shut-off valve but it still seems to be leaking. It is not the plumbing I installed. It's hard to tell because I have a protector around the tank but it seems the leak is coming from the top. I just took a short run down the highway and reparked it. I have a can't miss appointment so when I get back I'll see how much has leaked.
Is there some kind of overflow on top the tank? Everything is dry where the aux tank is plumbed in and the air pipe seems to be fine. If the leak stops with the shutoff closed then I'm just gonna head out but if not then I'm gonna take down the shield and see what I can find, but I'd sure rather not.

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.....

From diagnosis we are pretty sure we have clogged fuel pick ups in the tank of my 99 7.3 Dually. So in I go to clean and repair or replace depending on what it looks like once we get in there.
We have most of the fuel out of the tank, pumped out just over 30 gallons.
I don't have a lift so this is being done on the ground, any easier way ? The bed bolts look pretty rusty and funky but we have been spraying them down with Kroil, the magic elixir, for a couple days to see if that will ease the removal of the fasteners.
Take the Bed Off and work with the tank in the frame or drop the tank out and work away from the truck ?

Having trouble getting large plastic nut to start threading on top of the fuel tank sending unit, after doing in tank mods.
It just doesnt seem to want to start threading on properly. Its always cocked when it grabs, and after a while opposite side pops up and it falls off. Not sure how to get it back on there
Dealer has new ring for 18 bucks, maybe mine is warped or dried up since 2000?
