What are your tanks made from?
Transfer Flow tank systems are crafted with 12- and 14-gauge ReliaSteel®, high-yield U.S. aluminized steel (powder coated for a longer lasting, durable finish), or aluminum diamond plate.
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 more than 35 years for our aftermarket and OEM fuel tanks!
Why are Transfer Flow Tanks Expensive?
Our mission is to support our customers, community, and country by engineering and manufacturing premier quality “Made in the USA” fuel systems and vehicle accessories. Transfer Flow fuel tanks are made in America, by hard-working Americans, using only the finest U.S. materials and production equipment. Keeping our products premier and American-made is costly, but we firmly believe in the value and integrity of American craftsmanship.
Will I void my vehicle's warranty if I install a Transfer Flow tank?
No, using Transfer Flow fuel tanks will not void the vehicle’s warranty. The Magnuson-Moss Warranty – Federal Trade Commission Improvement Act of 1975 protects consumers from such fraudulent activity by new car dealers. Under this Act, aftermarket equipment that improves performance does not void a vehicle manufacturer’s original warranty, unless the warranty clearly states the addition of aftermarket equipment automatically voids your vehicle’s warranty or if it can be proven that the aftermarket device is the direct cause of the failure. The easiest way to check this is to look in your owner’s manual under, “what is not covered”. Under Magnusson-Moss Act a dealer must prove, not just vocalize, that aftermarket equipment caused the need for repairs before they can deny warranty coverage. If they cannot prove such a claim or offer an explanation, it is your legal right to demand compliance with the warranty. The Federal Trade Commission administers the Magnusson-Moss Act and monitors compliance with warranty law.
Can I use a Transfer Flow tank in conjunction with another after market fuel tank?
No, Transfer Flow fuel tanks are never to be used in conjunction with fuel tanks made by other aftermarket fuel tank manufacturers.
Does Transfer Flow sell gravity feed systems?
No, Transfer Flow does not offer a gravity flow system.
Are Transfer Flow tanks DOT approved?
Yes, Transfer Flow refueling tanks have received a special permit from the Department of Transportation to carry and transfer gasoline, diesel, ethanol, methanol, kerosene, and aviation fuel. See accompanying tank materials for DOT stipulations and decals.
Does Transfer Flow sell fuel tanks for gasoline vehicles?
Transfer Flow manufactures and sells DOT-legal refueling tanks that are approved to carry and transfer gasoline, as well as diesel, ethanol, methanol, kerosene, and aviation fuel.
Will a high capacity replacement tank affect my truck's stock fuel gauge and trip computer?
Your stock fuel gauge will read accurately when our high-capacity replacement tank is installed on your vehicle. When your gauge reads half full, you have approximately half tank of fuel. Most functions on your truck’s trip computer should work properly, except for the miles-to-empty feature. This feature will continue to read fuel levels as though you still have the stock tank installed.
Will I need to purchase additional parts to install a Transfer Flow tank?
No! When you order a Transfer Flow fuel tank system, you can rest easy knowing that you will receive a complete system with comprehensive step-by-step instructions and every part required for installation, down to the last zip tie! All high-capacity replacement tanks include mounting straps for secure underbody installation.
What is the difference between Transfer Flow TRAX operating system versions?
TRAX-UFS (1998–2004)
Trax-UFS was Transfer Flow’s first patented computer-controlled system for auxiliary tanks. This system came with auxiliary fuel tank, in-line pump, auxiliary sending unit, wire harness, computer module, installation kit, and dash-mounted LCD. It removed the need to manually toggle between main and auxiliary fuel tanks and automatically transferred fuel into the main fuel tank.
EXPRESS-UFS (2005–2011)
The EXPRESS-UFS auxiliary system came pre-assembled with the 70-gallon in-bed auxiliary fuel tank. This system included an auxiliary fuel tank, an auxiliary fuel pump, all mounting hardware, wire harness, fuel lines, and computer module. The computer module for this system was located with the tank unit and did not come with a dash-mounted display. In 2009, Transfer Flow redesigned all auxiliary tanks to use the EXPRESS-UFS system.
TRAX-II (2004–2013)
The TRAX-II system was the second patented computer-controlled system for auxiliary tanks. TRAX-II incorporated the computer module into the dash-mounted display and improved the transferring process from TRAX-UFS. This system included an auxiliary fuel tank, auxiliary fuel pump, all mounting hardware, fuel lines, and the computer module with LCD.
MAXFLO-TFI (2013–2015)
The MaxFlo-TFI module allowed for automatic fuel transfers from the auxiliary tank to the main tank. This version of the computer-controlled system did not come with a dash-mounted display or switch. The system did have an optional upgrade to include a small dash-mounted digital lightbar that displayed fuel level in the auxiliary tank only.
