F.A.Q.

What are your fuel tanks made from?

Transfer Flow replacement tanks are made from 12 and 14-gauge aluminized steel for superior rust resistance and strength, while our in-bed auxiliary tanks are made from 1/8” aluminum diamond plate or 14-gauge aluminized steel. Transfer Flow's DOT legal refueling tanks are manufactured from 12-gauge aluminized steel.

What is aluminized steel?

Aluminized steel is steel that has been electroplated with aluminum at the steel manufacturers. By electroplating the steel with aluminum, it acts as a corrosion resistant material. It’s the same material we have used for over 31 years for our aftermarket and OEM fuel tanks!

How hard are your tanks to install?

We recommend if you are installing a fuel tank yourself that you have excellent mechanical abilities. If you're looking for a company to install one of our fuel tanks, we have a list of over 300 companies that install our fuel tank systems throughout the U.S. and Canada.

Can I order a tank online?

Yes, our tanks are available to order online. In fact, occasionally we have special discounts for ordering online. Press here for our Factory Specials page.

Do Transfer Flow replacement tanks use straps?

Just like your stock OEM tank, we use straps to mount to the frame. Our tanks are never mounted directly to the frame rail!

Are your tanks baffled for extra support and durability?

Yes, all our tanks have baffles for extra support, durability, and to help reduce fuel slosh.

Do your tanks come with a warranty?

Our tanks come with a 3 year, unlimited mile warranty. Press here for our warranty information.

How will the larger replacement tank affect the truck’s trip computer?

Most of the functions will still work, except the miles-to-empty feature. It will read as though you have the stock tank still installed.

Will my stock fuel gauge read properly with your replacement tank?

Yes, your stock fuel gauge will read accurately when our larger tank is installed on your vehicle, so when you gauge reads 1/2 tank, you have approximately 1/2 tank of fuel.

Do your refueling tanks meet DOT regulations?

Our refueling tanks come with a special permit from the Department of Transportation. They are legal to carry gasoline, diesel, methanol, and kerosene.

Can I get parts for my non-TFI tank?

We do not sell parts for tanks made by other tank manufacturers because we do not know the legality of other tank manufacturers.

Do you have a tank installer near me?

We have over 300 fuel tank installers in the US and Canada! These companies have to pass our strict qualifications prior to being placed on our Fuel Tank Installer List! We can also install your tank at our facility in Chico, California.

How many years have you been in business?

Where are your tanks manufactured?

What is the difference between your TRAX-II™ and Express-UFS™ operating systems?

The main difference between TRAX-II™ and Express-UFS™ operating systems is that the TRAX-II™ operating system comes with a dash-mounted LCD display that displays the gallons in the main tank, the gallons in the auxiliary tank, and the total gallons on board the vehicle. It will also display when fuel is being transferred from the auxiliary tank to the main tank. Our Express-UFS™ systems do not come with an LCD display. For information on TRAX-II, press here. For information on Express-UFS™, press here.

Do you sell complete fuel tank systems so I don't have to locate other parts?

Yes, Transfer Flow sells complete fuel tank systems! All the parts and components, including straps, mounting hardware, bolts, etc., are included with our fuel tank systems!

Will I void my vehicle's warranty if I install one of your fuel tanks?

No! Installing a Transfer Flow fuel tank system on your vehicle WILL NOT void your vehicle's warranty The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket part. As defined by the FTC, an "aftermarket" part is a part made by a company other than the vehicle manufacturer or the original equipment manufacturer. A consumer has the right to patronize independent retail stores and repair shops for parts and service without fear of voiding the new car warranty. The dealer/vehicle manufacturer has the right to deny a warranty repair but they must demonstrate that the aftermarket part caused the problem. The warranty remains in effect for all other covered parts.
