Not every truck owner wants the biggest fuel tank.
Sometimes, keeping your bed space is just as important.
That's where the FuelBox FTC40 shines.
As the narrowest toolbox fuel tank on the market, the FTC40 is designed to provide additional fuel capacity while leaving more room for cargo, equipment, and the tools you use every day.
Its low-profile design sits flush with or below most bed rails and clears most gooseneck and fifth-wheel hitches, making it a practical solution for trucks that need to do more than just carry fuel.
Because the best upgrades don't get in your way—they help you get more done.

Need extra fuel capacity without sacrificing compatibility?
The FuelBox FT50 In-Bed Fuel Tank is designed with a low-profile height that works with most tonneau covers while providing an additional 50 gallons of diesel fuel capacity.
Built from heavy-duty .125 marine-grade aluminum, reinforced with internal baffles, pressure-tested for quality, and finished with Mil+Spec Liner protection, the FT50 is engineered for truck owners who demand durability and reliability.
Even better, it's compatible with the Auto Fuel Controller for seamless fuel management while you drive.
