Dee Zee Fuel Tanks: American-Made Toughness for the Long Haul

Dee Zee has been engineering premium truck accessories since 1977, and their fuel tanks reflect the same no-compromise philosophy that built their reputation. Designed for farmers, contractors, fleet operators, and serious weekend warriors, Dee Zee transfer tanks are purpose-built to move diesel and other non-flammable liquids safely and efficiently from your truck bed to wherever the work is happening.

Steel & Aluminum Construction — Built to Last

Dee Zee fuel tanks are available in two primary materials, each engineered for specific demands. Their steel tanks are constructed from heavy-duty 14-gauge steel and protected by Dee Zee's proprietary NRT™ (No Rust Technology) powder coat finish — a specially developed chemical additive that actively inhibits corrosion and weathering over years of exposure. For those who prefer lighter weight without sacrificing durability, Dee Zee also offers tanks built from non-rusting .125 Brite-Tread aluminum, which naturally resists oxidation and delivers a distinctive diamond-plate appearance.

Both material options share a radius curve design that eliminates key weld pressure points — a structural engineering detail that extends the life of the tank under the stress of loaded transport. Dee Zee also employs robotic welding arms for full-seam welds with precision and superior consistency that manual fabrication simply cannot match.

Smart Features for Safe Liquid Transport

Every Dee Zee transfer tank ships with a thoughtfully integrated feature set. Internal stability baffles divide the tank interior to control liquid movement during transit, reducing sloshing forces on the outer welds. A lockable cap, venting coupler, and a 3/8-inch drain plug make filling, pressure management, and full emptying straightforward and safe. Mounting tabs are included for secure, low-profile installation in your truck bed.

Dee Zee also offers L-shaped tank configurations designed to leave room for a crossover toolbox alongside the tank, and tank-and-toolbox combo units — including options up to 92 gallons — that integrate a full toolbox with gas-assisted lids directly into the assembly for maximum truck-bed utility.

Made in the USA, Backed by a Lifetime Warranty

Dee Zee manufactures the majority of their products at their facilities in Des Moines, Iowa, with most supplied parts sourced from American vendors. Their fuel tanks are proudly made in the USA and backed by a limited lifetime structural warranty, reflecting the brand's confidence in their materials and craftsmanship. It's a level of commitment that separates Dee Zee from generic import alternatives in the transfer tank category.

Whether you're hauling diesel to remote equipment, managing fuel on a farm, or simply extending your truck's range on a long haul, Dee Zee fuel tanks offer the reliability, safety features, and build quality that working truck owners depend on.
