Bigger gas tank.

Diesel spills are treated as hazmat incidents. I doubt the government is anymore lenient with diesel over regular fuel.

Please contact me when the group buy happens.

If I haven't bought an in bed I will be interested also.

Same here as for the interest. Factory tank is too small. When I hit the road I like to drive not stop ever few hours to fuel up. Hopefully something happens soon on the progress of these tanks.

I sent an email over the weekend to find out if there is any new information regarding the bigger tank.
Looks like they are getting closer to finishing the system.
Here is the latest. From the Sales manager.

(We have found some solutions to the purging issue on the engine and now have to work on getting
approval from ownership to re-test in Los Angeles again. We should know more early next week.)

(Cross you'r fingers! I know I am…….)

Here is some more information regarding the Transfer Flow fuel tank systems.


In the aftermarket fuel tank system industry, there is a lot of confusion over what is “legal” when adding or replacing a fuel tank. We hope the following information helps clear up some of these very important concerns. Be advised that this information is not intended to be a complete list, but rather a general overview.

For Vehicles Less Than 10,000 GVW
TFI fuel systems meet FMVSS 301 (Federal Motor Vehicle Safety Standards), VESC-22 (Vehicle Equipment Safety Commission), NFPA 1192, ANSI 119.2, RVIA (Recreational Vehicle Industry Association) regulations, CARB (California Air Resources Board), and EPA (Environmental Protection Agency) regulations. FMVSS 301 states that anyone who alters a vehicle must meet or exceed the structural integrity and performance of the OEM (Original Equipment Manufacturer) fuel system. A fuel system includes anything associated with fuel systems such as the fillneck, tank, gasoline lines, fuel pump, emission canister and fasteners.

In other words, if an alterer adds an auxiliary system to a vehicle thereby reducing the performance of the fuel system, he or she has violated FMVSS 301 standards. An example of performance reduction could be if fuel from the original system leaked because the auxiliary system was gravity feeding into the original tank. This creates a real concern as it not only violates FMVSS 301 regulations, but is also a hazardous waste problem.

TFI’s inboard chassis frame and in-bed tank systems meet and exceed the OEM systems in the following areas:
1.TFI tanks are designed using 14-gauge aluminized steel as a minimum instead of the 22 gauge terneplate or plastic that OEM typically uses. Transfer Flow’s aluminum diamond plate in-bed tanks are made from 1/8” thick aluminum.

2.TFI tanks are fully baffled unlike OEM tanks which have no baffles.

3. At a minimum, TFI tanks are drop tested in accordance with VESC-22. When drop tested, they are fully filled with water and cannot leak. Many of TFI’s fuel systems are also crash tested to FMVSS 301 standards.

4. Tanks are 100% pressure tested using a sophisticated automatic Helium testing machine. This machine is capable of finding leaks with a helium concentration of less that 1.00E-7 liters/sec (leak size of 0.0000000315 in-sq or 3.15 E-8 in-sq).

5. TFI tank systems meet the fastener (strap) regulations specified by ANSI, NFPA, and required by RVIA (Recreation Vehicle Industry Association).

6. TFI systems meet CARB and EPA emissions regulations. We design our systems with the correct emission canister capacity necessary for gasoline applications. GM, Ford, Dodge, etc. all use different canisters with different absorption characteristics. Each TFI fuel system is designed to be compatible with that vehicle’s emissions system.

7. TFI fillneck designs meet CARB fuel fill regulations. We design our fillnecks with proper alpha and beta angles and correct inclination angles for gasoline and diesel applications.

8. TFI systems meet CARB and EPA requirements concerning fuel fill rates. This test verifies that our system fills at a minimum of 10 gallons per minute - a rate equal to that dispensed at most gas stations.

That is a lot of information but does not tell us when or how much

Has anyone looked at the cost of comparable tanks on Transfer Flow's site? Ford tanks are anywhere from $700-$1200. With all the R&D and emissions work that's going in to the Tundra, I doubt we'd see tanks for under $1000, plus the possiblity of the expense of getting the DTE calculator re-calibrated. I drive a lot, but honestly, I couldn't justify that kind of cost. I know that there are RV'ers and others who drive more than I do, and there are those who just like to spend money on their vehicles... but at the price levels they advertise on their site, I'm a no-go. I'm going to need to see the tank a whole lot cheaper before I can justify it. I'm also out if the replacement tank hangs lower than the OEM.

This is why I think I a'm going the in the box tank 50 gal 550 dollars. I tow from NY to Florida and stopping every 170 miles gets old fast. Even older is making a gas stop and finding out you can't get in to the gas station.

Interesting thread, and I can't agree more that this fuel tank is too small.. This is my first truck (and I am damn happy I bought it) but my mom's old Mercedes had a 26 gallon gas tank. You would think in a truck, they would step it up.

I think Transfer Flow's email in a previous post may reveal something that we've missed- They said that Toyota's very small recovery canister (if I recall correctly) is making it difficult to engineer our systems. I think the small canister may reveal a cost-saving measure by Toyota. If larger tanks require larger and presumably more expensive evap recovery systems, competitors like Ford would have to incur the expense of using 2 different systems on trucks with different size tanks.... or just use one larger system for all models. If a larger system is more expensive, it doesn't make sense from a cost standpoint to use the larger system on all models when most of the models sold (5-6' bed) trucks use the smaller tank.
Just my $.02.

My F150 had 2 tanks which totalled 40 gallons. I could go over 500 miles before refueling and still be safe. 26 is rather small. I have to fill up every few days. The smaller tank isn't a show stopper, but it would be nice to have another 10 gallons or so.

[EVOL ARDNUT]

I remember dads old F 250 had the dual tanks you could switch back and forth, what was that like 45 gallons total??

NOW THAT WAS STEEL....YOU COULD BUILD A COROLA JUST WITH THE METAL FROM THE HOOD!!

[shooter2jim]

I think dad's '77 F350 had that with the electric switch, but the fun one was my '74 Bronco which had a mechanical control valve located on the front of the driver's seat floor platform. Whenever the engine started sputtering, I had to reach down and rotate the lever 180 degrees to switch tanks. Then flip the switch on the dash to make the gauge read the other tank. Forget to flip that switch to check the level on the other tank and you'd be hoofing it.

There is between 2 to 3 feet empty space between the back of the tank and the rear, on our tundras.
And as I understand, same tank will fit all of our tundras, unlike the Ford, Dodge, or GM.
We are willing to spend $300 + bucks for CAI. Some of us over $1000 for cat back system. $500 + for Headers. And all that doesnot give us so much noticeable improvement, Then why not spend money to make our longer trips and long towing easier? My crew max bed is small as it is and I dont need to make it any smaller. I will defenetly go with original tank replacement.
And I will not stop talking to the Manager from Trueflow systems untill he gives all of us a good deal.
