Gravity Feed Auxiliary Diesel Fuel Tank
With a reserve diesel tank crafted by Aluminum Tank Industries, you can go farther than you ever thought possible without stopping to gas up. Leonard Accessories can set truckers up with an assortment of backup fuel tanks that add anywhere from 30 to 66 gallons of capacity. In most cases, this more than doubles the total mileage between fill-ups, which is a big deal for overnight transport or traveling to remote areas.

Unlike a fuel transfer tank that uses an external pump, this auxiliary diesel tank uses the power of gravity to feed into the factory fuel system. Choose the appropriate Fuel Shotz Gravity Feed installation kit for most Ford, Chevy, and Dodge diesel trucks.

The ATI diesel truck bed has everything else you need for rugged driving conditions, including:

  • Gravity Feed Installation Kit
  • Automotive-style filler cap
  • Fully baffled to limit movement
  • A pressure-tested, fully inspected design
  • A reinforced bung
  • Welded hold-down brackets

Want to use this tank with a truck model you don't see listed? Contact our in-house truck experts by phone or live chat. Leonard Accessories will help truck owners drive as far as they need to with accessories offered at great prices as well as great service.

Go Further and Longer - adding a diesel auxiliary fuel tank can give you an additional 30 to 66 gallons on top of your factory-installed tank's capacity, more than doubling your range in most cases. Not to be confused with "Transfer Tanks", these rectangular auxiliary tanks are not designed to be used with external pumps. The vehicle fitment list on this page is for the installation kit only. It does not ensure the fit of the tank. 

No Guesswork - ATI auxiliary tanks increase your driving range and fuel capacity by as much as 66 gallons by connecting directly into your factory fuel tank through the factory filler neck. These tanks are designed for use with the included Fuel Shotz diesel install kits. This will keep your factory tank completely full until the auxiliary tank is empty. You will know your auxiliary tank is empty when your factory fuel gauge moves off the full mark. Auxiliary fuel tanks can also be used to supply fuel to the engine of machinery and equipment such as generators. Our auxiliary fuel tanks meet all the necessary DOT requirements.

Hook Up - The FUEL SHOTZ auxiliary fuel tank installation kit that is included is used to connect the auxiliary fuel tank to the factory fuel tank via the factory fill tube. The kit contains everything you need to make the connection from the auxiliary tank with a 3/8" NPT bottom fitting to the factory fill tube. The auxiliary tank keeps the factory tank full. When the auxiliary tank is empty your factory fuel gauge will move off the full mark. These kits are supplied with detailed instructions and take less than an hour to install. There are no wires or switches to install, engineered for rollover protection, and only requires attaching the kit supplied 3/8" npt pipe fitting on the bottom of the tank in place of the drain fitting.

You Have a Little Work To Do - ATI 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"
