Product Description

The DeeZee 40 Gallon Aluminum Auxiliary Diesel Fuel Tank is a DOT-approved, truck-bed mounted solution designed to safely extend the driving range of diesel-powered vehicles. Constructed from non-rusting aluminum with a Brite-Tread finish, this auxiliary tank is engineered for durability, controlled fuel movement, and long-term reliability in demanding work environments.

This tank is designed for gravity-feed operation, allowing diesel fuel to flow to the vehicle’s fuel system when properly installed. In addition, the tank can accommodate a top-mounted 12V transfer pump for dispensing fuel to external tanks, equipment, or machinery, independent of the gravity-feed system. These functions operate separately and do not interfere with one another.

Full-size, fully welded internal baffles create multiple compartments within the tank to control fuel movement, reduce sloshing, and minimize stress on outer welds and traditional 90-degree weld points. The vented locking fuel cap allows the tank to breathe during transport and fuel movement, reducing internal pressure and eliminating vacuum formation.

Hydrostatically pressure tested to 29 PSI and compliant with Federal Motor Carrier Safety Administration requirements, this auxiliary diesel fuel tank is built for professional and commercial use. The toolbox-free design allows flexible truck bed layouts and easy integration with gravity-feed plumbing or optional dispensing accessories. Backed by a limited lifetime warranty.
