Fuelbox Tanks

Fuelbox specializes in premium truck fuel tank toolbox combos and auxiliary fuel transfer tanks. All Fuelbox combos can be utilized in two ways:

  • As an auxiliary fuel tank for your diesel pickup, the Auto Fuel Controller will transfer fuel to your pickup's factory tank as you drive. 
  • It will also transfer fuel to other vehicles and equipment with one of the optional transfer pump systems that mount inside the toolbox so it is secure and out of sight. 

Fuelbox tanks are fully compliant with DOT and EPA regulations for diesel pickups in all 50 states, thanks to the patented Auto Fuel Controller (AFC) system. The AFC system is easy to use and install, and for 2008 and newer diesel pickups, Fuelbox offers the Plug & Play Auto Fuel Controller, which utilizes the OBDII system.

Fuelbox offers AFC systems for all Ford, GM, and Dodge diesel pickups, making the operation of Fuelbox auxiliary fuel tanks effortless.

Finish

All Fuelbox tank's come standard with smooth or diamond plated silver.  You can add the following options to the finish:

  • Charcoal black spray liner - adds a durable coat of sleek black spray liner to the Fuelbox.  This helps preserve your Fuelbox in the outdoor weather as well as makes it really stand out.

Auto Fuel Controller

  • Auto Fuel Controller Kit - automatically transfers fuel to your diesel powered factory tank.
  • Plug and Play - alternative option for transferring fuel to your diesel powered factory tank.
