Add real-world range without sacrificing bed space. This low, 7-inch-tall rectangular auxiliary tank tucks neatly in the bed and even fits under many low-profile toolboxes, making it ideal for daily work trucks, tow rigs, and long-haul adventures.

Engineered for diesel, the tank is DOT-compliant and designed for gravity feeding to your factory tank when paired with a compatible diesel install kit (sold separately). Internal baffles help control slosh on rough roads, while a rollover safety vent, lockable filler cap, and 3/8 in. FPT drain plug deliver confidence and convenience.

Built to last, it’s crafted from 0.125-in (1/8-in) diamond-plate aluminum with fully welded seams and every tank is 100% pressure-tested for leaks. Aluminum construction won’t rust, keeping fuel clean and components looking sharp season after season.

Whether you’re towing a fifth wheel, hauling equipment to the jobsite, or chasing backcountry miles, the extra 20 gallons means fewer stops and more time getting it done. Shop smarter by buying fuel where it’s priced right, not just where you’re forced to stop.

Proudly made with American workmanship, this tank reflects the toughness and reliability drivers count on. Check local regulations and vehicle compatibility before installation. Diesel use only; not intended for gasoline.
