Dee Zee Fuel Transfer Tank
Dee Zee Fuel Transfer Tanks: Built Tough, Made in the USA
When your work truck or farm rig needs a reliable fuel hauling solution, Dee Zee has long been a go-to name for serious operators. Their lineup of fuel transfer tanks is engineered around two core principles: structural integrity and on-road safety — and the engineering choices behind every tank reflect that commitment.
Two Material Choices, One Standard of Quality
Dee Zee manufactures their transfer tanks in both aluminum and heavy-gauge steel, giving buyers the flexibility to match material to application. Aluminum models are built from non-rusting .125 Brite-Tread aluminum — a diamond-tread surface that resists corrosion by design. Steel models are protected by Dee Zee's proprietary NRT™ (No Rust Technology) powder coat finish, a rust-inhibiting coating applied over heavy-duty 14-gauge steel for long-term corrosion resistance in demanding environments.
Regardless of material, every Dee Zee tank shares the same signature radius curve design that eliminates key weld pressure points — a structural detail that directly contributes to tank longevity under heavy loads and rough terrain.
Safety-First Engineering: Baffles, Caps, and Pressure Testing
One of the most overlooked hazards of transporting large volumes of liquid is fluid surge — the momentum-shifting effect of fuel sloshing inside the tank during acceleration, braking, and cornering. Dee Zee addresses this directly: their transfer tanks feature three internal stability baffles to reduce the effects of fluid movement while driving, improving vehicle handling and safety on the road.
Aluminum auxiliary models certified for diesel fuel are hydrostatically pressure tested up to 29 PSI and meet Federal Motor Carrier Safety Administration (FMCSA) requirements, as well as Federal DOT standards for UN31B tanks. Every tank also includes a lockable cap, a 3/8-inch drain plug for complete emptying, and a venting coupler to maintain pressure balance during transport.
Capacity Range and Product Variety
Dee Zee's fuel transfer tank catalog spans a wide range of capacities — from compact 39-gallon rectangular tanks ideal for mid-size pickups, all the way up to 106–111-gallon configurations suited for full-size work trucks and farm equipment. Auxiliary tanks in the Brite-Tread aluminum lineup can even be connected to a gravity flow kit to siphon diesel directly into your truck's fuel tank, extending range without stopping for fuel. For operators who need maximum utility, Dee Zee also offers Transfer Tank + Toolbox Combo units — purpose-built truck bed solutions that pair a large-capacity transfer tank with a fully integrated, gas-assisted toolbox lid for organized gear access alongside your fuel supply.
All Dee Zee transfer tanks are proudly manufactured in the USA and backed by a limited lifetime structural warranty — a testament to the confidence Dee Zee places in their own construction standards. Mounting tabs are included on every model for a straightforward truck bed installation.
Whether you're a diesel technician, a rancher covering hundreds of acres, or a contractor keeping heavy equipment running at a remote job site, Dee Zee's fuel transfer tank lineup delivers the capacity, durability, and safety features that hard-working applications demand.
