TV Auxiliary Fuel Tank
I currently have a 2016 F-250 SD 6.7L Deisel TV. The stock fuel tank is too small so I am thinking of adding an Auxiliary Fuel Tank. I have researched a replacement tank, but I think adding an additional tank is for me. I want an in bed tank with an attached tool chest. Approximately 70 to 95 gallons. That would allow me to make my long trips without stopping every 150 miles or so to top off.
What brands are good and how difficult are these tanks to DIY? Any information or recommendations are greatly appreciated. Thanks!

TV Auxiliary Fuel Tank
Transfer flow is a popular brand, just remember, if your adding 70 gallons of fuel how much weight are you subtracting from GVWR?
Diesel fuel is about 7lbs/gal. 70X7=490 plus weight of tank.

Titan fuel tanks is another. They have several options to choose from.

I went through the very same thing this past spring when I still had my F250. I added a 42 gallon "L" shaped tank and put the bottom part under the existing truck bed tool box. It was a great setup, but as Chuckster stated, that eats up a LOT of your available payload capacity on the truck. By the looks of your picture, you've already got quite a load on the F250, so adding another 800 lbs or more of weight to the truck bed is almost sure to overload your truck. My 2011 F250 Crew Cab 4x4 with the XLT package on it had a payload of, get this.....2148 lbs. My 42 gallon tank and electric pump and fuel filter setup, along with 42 gallons of diesel in it added up to a little more than 550 lbs. So my available payload dropped from 2148 down to under 1600 lbs of payload. I's say you've got more pin weight than that on your setup and you're talking 70 gallons of diesel, not 42. Lots to think about before you make a move there.

Thanks for the info, I had not thought of all of that. I'll have to check it out thoroughly before jumping in. I'll get some stats together and re-group.

I have a ATTA tank, they have some really nice options to include a fuel gauge, check out their website. Regardless of what brand you decide to go with I would recommend buying their vent line adapter for $20. Its the easiest way to plumb it into your fuel system. Just cut the existing vent line, install the adapter, run the fuel line to it and the return line back to the tank. I also run a Holley electric fuel pump on mine with a toggle switch on the dash. The fuel pump only needs to be run for a few seconds to establish a syphon. For the most part the entire tank will syphon as you drive. Every now and then it'll break syphon, then just run the pump again for a few seconds. Installation of the entire system is pretty simple, plan on a couple hours.

As they should be when someone starts talking about adding nearly 1,000 lbs to a 250/2500 in addition to their pin weight and other cargo. Putting 3500-4000 lbs of payload on a 3/4 ton truck is definitely not a good idea.

Thanks for the tip. I'll check it out. I did research the weight issue and all are correct on the limited payload. I would be pretty close to max with the heavier tank.

You might want to check your numbers again, your probably pretty close to max payload before you add the tank. Your 5er probably has a dry pin weight around 1500, probably a bit over 2,000 loaded up for camping. Add hitch, you and your family, fuel from the OE tank, and anything else you add in and your probably in the 2,500-3,000 lb range loaded up and ready to go. Your 250 payload is most likely in the 2500 lb range. Adding an auxiliary fuel tank to a 3/4 is nice, but I'd definitely recommend staying in the smaller 30-40 gal sizes. Even if you can get 60 gallons total of fuel, you should be good for 600+ miles. That should be enough to keep you from having to fuel up until you stop for the day.

That's true, it would be nice to have and would help to have the extra fuel on board. But with the weight limits I have to deal with it sounds pretty impractical. I'll have to think on some other option. Thanks again for all the information. There was a lot there I did not take in to account.

Ya know Frank, there really are some people that appreciate good advice.....I'm assuming that you aren't one of them!

Mike, I have installed two of these tanks over the last three years. http://www.northerntool.com/shop/too..._541559_541559
If I drive up on my 4x8 when I fill it will hold a total of 45 gallons. It is completely gravity driven, no moving parts and couldn't work better. Both installations were on Super Duty Fords, one a 2014 and one a 2015. If you need more info just PM me. That way those who tow their Raptor 420 with their Mazda pickup won't interfere with inane remarks.

It's "they're".......not "there". You're welcome!.......and I won't even write you a ticket this time.

The gravity feed tanks seem to work well, but if you read the reviews there are several people who have experienced overflow conditions and dumped a bunch of fuel on the ground while parked. Those people end up shutting off the valve until fuel is needed, then open it and let if fill the main tank. Obviously, not everyone is experiencing this issue and I have not been able to figure out if the ones who do are doing something different.

Thanks again for all the inputs, and the GREAT advice! These posts opened my eyes and will be very helpful in my decision making process. I'll be mulling this over in the near future. Since this my first 5er (my most recent RV was a motor home with a 75 gallon tank so distance was not a problem), I'll get all of the weight issues settled and move forward. Although the price for the titan is a little steep, that may be a viable option as well.
