had the transfer flow shipped directly to my Ford dealer, after a conversation, and had them install the tank and get rid of the OEM tank. nice thing about Ford, you simply tell the on-board computer what the capacity is and the gauge reads correctly, nifty. very nice to have the extended capacity although if the crew cab had come with the 36g tank, i would not have bothered. i have no idea what Ford is thinking about, perhaps GVWR, don't know.

I read that there is some that have concerns about retro-fitting their TV with extended range fuel tanks. Let me offer this.

Concerns about water in the fuel in regards to extended range tanks should be filed under " vehicle maintenance".

Anytime you are dealing with diesel fuel, water admiration is part of the package.

Draining the fuel separator ever so often is part of normal operations. This is why there is a warning indicator on dash board, that you never want to see turn on, telling you that water has filled up to a point you must take action.

This is the same thing as "you have X number of restarts" before the DEF gods put you in the ditch.

Every second tank of fuel with an extended range tank my vehicles receive a pint of "diesel" fuel treatment and a short dump of the water seperator and life is good.

My only real issue with the extended range tank is I don't have the range the vehicle does. When I step out I have to stand up and hold on till my legs start working. )

Happy trails.

Auxiliary tank

I added a large DeeZee tank in the box. Plumbed it to the filler hose of the factory tank after inserting a $3 Walmart filter in the line -a must. It is great to buy fuel at my option and saves some money when going to high price areas. Yes, costs something to haul it around. I don't always carry extra if we are near home.

We miss the box space and would have definitely gotten an 8" box fi we had known...

My Vote Is Titan!

I have a 2015 F-350 KR Crew cab with the 6'8" bed and a Leer shell. I also hated the 26 gallon tank. I did not want to sacrifice any space inside the bed so I opted for the 50 gallon Titan replacement tank. Titan uses Military grade materials and they fit like a glove! Much better tank than the original. I also opted for the shield, which protects the bottom from any kind of impact. Now I can tow all day before needing fuel. You can't even tell the tank has been replaced in looking at the truck.

We had the stock 34 gallon tank replaced with Titan 56 gallon tank and shield installed on our Ram. It only hangs about an inch lower than the stock tank (which, if anything has lowered our center of gravity a little).

IMHO these trucks ought to come with larger tanks from the factory.

Although the Ford dealer was origianally reluctant to do it I replaced the tank in our 2012 F250 with the Titan 50 gallon tank. I love it. It makes travelling long distances so much easier as you can pick and choose when to stop because you don't have to stop for fuel as frequently.

Strongly recommending upgrading if you can.

While my truck is a gas rig, I really needed more fuel so I went with the Transferflow since titan doesn't make a tank for gas rigs. I am very happy with the Transferflowsince my gallons went from 28 to 47 and I have an extended cab short bed, the shortest 3/4 ton made. Towing our AS, I can make it over 450 miles between fillups, but I have to pee before that happens.

We have your exact truck and it came with the 26 gallon tank. All I was ever doing was searching for a fuel station. I ended up buying the Titan 50 gallon tank that replaces the original. I had the local Ford dealer install the tank and recalibrate the computer for the larger tank. The install went fine and the calibration is spot on.

The Titan tank cost was about $1,100 and I also purchased the skid plate Titan sells that goes under the replacement tank. That skid plate was about $300. Install at the dealership was also about $300. So I have about $1,700 into the new tank. The tank uses your original fuel pump and sending unit.

I'm really happy with the distance I get with the new tank. There are probably cheaper ways to carry more fuel but that's what I settled on. Good luck on your decision.

Titan 50 gallon

Last year we replaced the fuel tank on our 2011 Ford F250 diesel because we had planned a 6,000 mile trip to Mt. Rushmore and Yellowstone for this July. The puny 26 gallon tank had proved to be a big inconvenience when going on longer trips. We went with the Titan replacement tank because of the reviews and the quality of the materials that are used in the tank construction. Best decision we ever made. I didn't worry about finding diesel fuel, as I now have a towing range of over 600 miles per tank without losing any truck bed space.
The Ford dealership did the replacement work and reset the computer that calculates miles to empty. No problems at all.

My Ford dealer looked at me like I was crazy when I asked them to reset my computer for the larger tank. I get the low fuel buzzer when I have 1/3 of a tank. Perhaps I should find another Ford dealer.

I have the same problem. They did not reset my fuel computer so wondering how difficult is it to reset the computer on a 2012 F 250 diesel
