Transfer Flow fuel tanks are the next level in refueling and transfer tanks. TransferFlow Refueling and Transfer Tanks are DOT legal for gasoline, aviation, diesel, methanol/ethanol, and kerosene. Produced with U.S. sourced ReliaSteel*, this 14-gauge, aluminized steel provides higher resistance to external heat and corrosion than plain steel and is much stronger than the aluminum used for most diamond plate and mill-finish tanks.

Transfer Flow's refueling tanks all have their high capacity, 12Volt, 15 gallons per minute (40 gallon tanks have an 8 GPM pump) GPI pumps mounted below the top of the tank. That means no pump sticking out way over the top of your bed. In fact, most of these transfer tanks have an overall height that would rise only a few inches above most typical truck beds.

The tanks here are transfer tanks.  The sample instruction video is for a 70 Gallon Auxiliary tank.  It displays how the 70 Gallon tank is adjustable.  Its unique design allows you to maximize the storage area.  However, the video also demonstrates the auxiliary tank to tank hook-ups along with the TRAXX system installation.  These transfer tanks do NOT require a tank to tank hook-up or wiring.  Use the video as a reference for the tank's bed installation. 

You Do Have Some Work To Do - Transfer Flow offers many different configurations, capacities, and shapes but measuring the area you intend to mount your tank is the only way to correctly choose the right tank for your truck. Use our guide "How to Measure Your Truck Bed for a Transfer or Auxiliary Tank"
