Features:
If you're tired of watching the fuel gauge drop fast during long hauls or off-grid trips, the Transfer Flow 40-Gallon Toolbox and Fuel Tank Combo gives you the freedom to keep going without constant stops. Built for serious truck owners who need more range and secure gear storage in one unit, this system combines a high-capacity auxiliary fuel tank with a rugged locking toolbox. Whether you're towing heavy loads through mountain passes or working remote job sites all week, having 40 extra gallons in the bed means fewer fuel stops and more productivity. The flush-mount design keeps the profile clean and matches your bed rails like it came from the factory, so you're not sacrificing looks for functionality. The stainless steel paddle handles, gas-filled shocks, and black powder-coated finish show this thing was built to handle the real world, not just look good online. With DOT approval for transporting everything from diesel to aviation fuel, it’s a go-to for anyone who needs flexibility in their fueling setup. Add in the 12V fuel pump, 12-foot hose, and dash-mounted switch, and refueling your truck or equipment is as easy as flipping a switch and squeezing a nozzle.
This Transfer Flow 40-Gallon Fuel Tank and Toolbox Combo is engineered for those who rely on their trucks day in and day out. Constructed from heavy-duty aluminized steel and protected by a corrosion-resistant black powder coat, the tank is designed to last through years of tough use. The built-in toolbox features stainless steel locking paddle latches and gas struts that allow the lid to open smoothly and stay open, making it easy to access your tools or gear on the go. Inside the tank, internal baffles reduce fuel movement during driving, improving vehicle stability when the tank is full. It comes as a complete refueling system with a 12V pump, 12-foot fuel hose, and a dash-mounted switch and harness, giving you full control without leaving the cab. DOT Special Permit SP-11911 certification ensures it's legal for transporting gasoline, diesel, methanol, ethanol, kerosene, and even aviation fuel. If your truck is part of your livelihood, this tank setup adds the range, utility, and reliability you need.
