Auxiliary Fuel Tank

[ranchdog]

Who has an auxiliary fuel tank, preferably diesel but the gas guys might want to know too. Please specify type and a link if possible and what do or don't like about it. I am looking at one with a tool box, http://www.northerntool.com/shop/to..._sku=3490107&gclid=CMjQ4LeE0cMCFQQLaQod6BUAZQ.

This is what I have...Awesome when I'm towing covered by the roll up cover when I'm not.....Installed it a couple of weeks ago....Good product easy install.

I have the Northern Tool 45 gal. vertical tank. The tool box would be nice but with my short bed truck I wanted the extra bed space.

Mine was shipped from the Florida factory to a freight warehouse in town. They would have dropped it at my home but I was not home so I picked it up at the warehouse. I also bought their gravity fill option. It all works great.

I would never tow a trailer without an aux. tank.

I have a 2012 F250 and I replaced my stock fuel tank with a Titan 50 gal tank. its only 25 more gallons but I have more free space in the bed of my truck. I like it. www.titanfueltanks.com.

I have the RDS Fuel Tank Toolbox Combo — 51-Gallon Capacity, Model# 72746...from northern tool & equipment....It is a gravity fill tank, and I am really happy with it.... Money well spent !!!

I have a Transfer Flow combination fuel and tool box. 40 gallons of diesel and a good sized tool box. Works seamlessly with the OEM system and the monitor, which mounts on the dash, shows how many gallons are in both the OEM tank and the auxiliary tank and the combined amount. Even the stock fuel economy reading on the DIC still works. Very happy with it. Between the 2 I carry about 65 gallons.

I'll be installing a Transfer Flow replacement tank next month. The original tank in my F350 is 26 gallons. At around 11 mpg while towing, this limits me to about 250 miles before I'm running on fumes. We usually like to travel 200 to 300 miles a day. So this means that we always have to stop and fill up along the way. I'd much rather be able to make it to camp, unhook, then fill up. It's such a pain to find a place to fill up when you are towing.

With the 50 gallon Transfer Flow tank, I'll be able to get more than 500 miles on a tank while towing. Here's a link to the tank I'm buying.

I know you said you looking at an auxiliary tank, but I too went with the mid-ship replacement. I can travel 750+ miles on one tank without my trailer. So I figure I could get about 350 ish miles with my 5er in tow. But becaus you have the long bed, you could get the 65 gallon mid-ship one.

Here is what the 26 gallon and 50 gallon look like side by side



I installed it in my garage in 3 hours (had to stop a few times because of distractions). Just something else to consider.

I have this same tank (45 gallon with their freedom fill system) and am very pleased. Their facility is in north Fort Worth (near the Stockyards). Note that there is a lot of added weight with a full load of fuel (71 gallons).

Just Finished Installing RDS 60 gal. fuel/tool box combo

We play the Gas Buddy game as we travel and since each of us are already towing the cleanest restroom, favorite kitchen and most comfortable bed to be found in any part of the country that we happen to be in, why would we want to stop in some dirty truck stop or other station when we don't have too!

So...for all of these aux tanks in the beds, are you installing a fuel pump to move the fuel from the aux tank to the main tank? If so, how is connected? A Tee into the filler neck, or directly into the main tank?

Everything I find on the Transfer flow is for the pump handle style, and the TitanTanks provide a gravity siphon. Both of these options means I have to stop and transfer the fuel from the aux tank to my main tank.
Keep in mind I have a gas vehicle so a replacement tank is not an option for me from either TransferFlow or Titan Tanks. Auxiliary tanks seem to be my only option.

Hey TENN22,

All of this auxiliary tank discussion is specific to diesel fuel.
You will not find any auxiliary or replacement tank manufacturer willing to take on a gasoline application.
Too many flammability and evaporative emissions standards to meet.

The best you can do for "extra" fuel is a proper jerry can secured in the box of the truck.

As Rob said, this auxiliary tank is for diesel only and it is a gravity fed tank connected by a Tee in the filler neck. No pump. Illegal for gasoline.

99.5 to 2003 SuperDuty short bed trucks have a 33 gallon tank, however the bad design of the in tank fuel pickup limits fuel capacity to only 29 gallons.

A "Harpoon Mod" can be done with copper tubing and fittings found at any hardware store so owners can get 33+ gallons into the tank. There will be no in tank screens to clog.
You can easily check the see through pre-pump filter. There's no more fuel regurgitating out the fuel filler neck when refueling. And best of all, less fuel aeration results in a much quieter fuel injection and minimizes engine noise.

There are pictures online that can be found by Googling "Guzzle's Harpoon Mod."

Thanks for your reply, but this has very recently changed.


Titanfueltanks.com just released on March 9th an in bed fender saddle auxillary tank for gas.
Transfer flow now makes two inbed aux tanks for gasoline as well.
Apparently they can only be used as aux tanks with a manual fill method though. This is why I was asking about options to transfer the fuel into my main tank.

I only point this out for other gas owners who might be following along.

 

[cgoodnight]

Titan saddle tanks use a siphon to transfer the fuel to the main tank. Transfer Flow says they never use gravity fill. Their inbed tanks require you to stop and use a pump. Either way you have to stop to refuel if you have a gasoline engine.

Northern Tool tanks use gravity fill or one can add an electric pump if desired. Diesel only, though.

It appears, TENN22, that your only options all require you to stop to refill. Since I stop to take breaks while traveling I would not find that a big problem; better than running out of fuel in the middle of nowhere. But everyone is different.

Good luck in your search for what will work for you.

[cgoodnight]

Yes, Transfer Flow does have a Trax II or something to fill their tanks. And they show it can be used for F250 gas engines in several model years (not late models). I remember this whole system is expensive.

My Northern Tool 45 gal tank cost around $450 plus $100 for the gravity fill system. I installed the tank myself. Did not want to spend $2000 or so for the Transfer Flow and Trax II system and the installation.

 

[tonyself]

We have just had a new F450 arrive at the dealer and they are fitting a replacement www.transferflow.com under tank and toolbox tank which will give us 97gal of Fuel will hope this will give us a good 3 days of driving!
Will post a update after our first trip with the new Ford.

 

[ranchdog]

Just a note for the cost conscious. RDS fuel tanks, auxiliary or transfer, are sold by Northern Tool, Amazon and Nationwide Wholesale Direct with the latter usually being the least expensive. They are aluminum and come in bright aluminum or powder coated black. Installation of the gravity flow system is very simple and is best accomplished by two as there is action required both above and below the truck bed. I have no interest in any of these entities but I try to be as selective as possible spending my discretionary dollars so I'm just passing on some information that might save you a dollar or two.
