Diesel Fuel Storage and Secure Tooling in One Unit

The Fuelbox Fuel Tank Toolbox Combo is a vetted, commercial-grade storage system built for diesel trucks. Constructed with .125 inch marine grade aluminum and featuring 90-degree flange reinforced seams, this combo demonstrates serious craftsmanship. It functions universally as an auxiliary tank, a transfer tank, or both, while sitting flush or below your bedrails to clear most gooseneck and fifth wheel hitches. Every unit includes a charcoal spray liner inside and out. This is a smart investment for fleet managers needing secure tool storage and extended fuel range without sacrificing bed space.

The Fuelbox can be used in two ways:

  • As an auxiliary fuel tank for your diesel pickup. Use the Auto Fuel Controller to transfer fuel to your pickup as you drive.
  • Use the optional transfer pump to transfer fuel from the Fuelbox to other vehicles and equipment.  The optional transfer pump mounts inside the tool box so it is secure and out of sight. 

Choose a Transfer Pump or the Auto Fuel Controller

Option 1: Use your Fuelbox as an Auxiliary Tank

Fuelbox Auto Fuel Controller (AFC) – Auxiliary Fuel System:

The AFC computer works in conjunction with the Fuelbox tank by automatically filling your main fuel tank when it gets low as you drive and shuts off when the main tank gets near full. The AFC monitors the stock OEM fuel tank.

When the stock tank gets near 1⁄4 of a tank it will turn on a transfer pump and transfer fuel from the auxiliary tank to the stock tank. The AFC will shut off the transfer pump when the stock tank is near full or the auxiliary tank is empty.

The AFC can be set for automatic operation or it can be manually turned off
from the cab of your truck. In addition there is a manual button, where you can manually transfer fuel for up to 4 minutes.

The Auto Fuel Controller (AFC) makes the Fuelbox tanks legal in all 50 states for diesel pickups. The AFC system meets or exceeds all DOT & EPA regulations. It also meets the standards required by the VESC-22.

Auto Fuel Controllers (AFC) systems are compatible for all Ford, GM and Dodge diesel pickups.

The Auto Fuel Controller is available in two models: Digital Display Controller or Plug & Play Controller.

  • Plug & Play Controller: plugs directly into your on-board diagnostic (OBD-II) port on your truck. This makes an easier install and avoids the factory wire harness. The plug and play shows the fuel level percentage in both the vehicle tank and the Fuelbox tank.
  • Digital Display Controller: is a vehicle specific controller that is programmed for the year and make of the vehicle. The Digital Display controller only shows the fuel level in the Fuelbox tank.

Option 2: Use your Fuelbox as a Transfer Tank with a Fuel Pump

The fuel transfer pump allows you to fill other vehicles and equipment. The transfer pump is a 13 gallon per minute pump with a 12 foot hose and an auto shut-off nozzle. 

Transfer Pump Accessories:

  • Filter Kit – Adds filtration to your transfer pump.
  • Fuel Meter – Logs how many gallons you transfer with the transfer pump.

Fuelbox Optional Accessories:

  • Tie down bar – add more mounting tie down points that are easy to reach.
  • Side bed step – mounts just behind the cab, providing a faster & easier way to reach your Fuelbox.
