Maximize Your Efficiency with Dee Zee’s Long Rectangle Auxiliary Tank

Frequent refueling stops can disrupt your workday or extend your travel time, especially on long trips with your 5th wheel trailer. Dee Zee’s Long Rectangle Auxiliary Tank provides a reliable solution for extending your fuel range, whether you're refueling equipment on-site or transferring diesel directly to your truck’s tank.

Built for Durability and Performance

Constructed from non-rusting .125 Brite-Tread aluminum, our auxiliary tanks are designed to endure the toughest conditions. The radius curve design eliminates key weld pressure points, while hydrostatic pressure testing up to 29 psi ensures top-notch quality and safety.

Efficient Fuel Transfer

With our sophisticated connector kit (sold separately), you can confidently bypass refueling stops and transfer fuel directly from your auxiliary tank to your truck’s fuel tank. Our tanks meet Federal DOT and Federal Motor Carrier Safety Administration requirements, ensuring they perform reliably as an auxiliary fuel system.
