Portable DEF Tanks - Fuel Transfer Tanks - Two Compartment Tanks
Premium Portable DEF Tanks & Mobile Transfer Systems Diesel Exhaust Fluid (DEF) is the lifeblood of modern Tier 4 engines, but it is also their biggest vulnerability. If you let dust, debris, or moisture into your fluid, you aren’t just looking at a clogged filter—you are facing thousands of dollars in injector repairs and crippling downtime. You need more than just a plastic container; you need a sealed, secure transfer system....
At Tank Depot, we stock the industry-leading Enduraplas DEF Fuel Boss™, the ultimate solution for safe, mobile DEF dispensing. Unlike cheap transfer vessels that allow condensation to form and contaminate your supply, our portable DEF tanks utilize proprietary Condensate-Armor™ technology to keep your fluid pure.
Whether you need a compact 25-gallon DEF tank for a service truck or a robust 100-gallon DEF transfer tank for a construction site, these units arrive fully assembled and ready to work. Forget about hand-pumping or struggling with heavy jugs. With integrated 12V pumps, auto-shutoff nozzles, and a "tank-in-a-tank" design that protects your equipment from the elements, the Fuel Boss is the professional’s choice for mobile refilling.
Applications of Our Portable DEF Fuel Transfer Tanks
Agricultural Field Service
Harvest season does not wait for you to drive a sprayer or combine back to the barn just to top off the exhaust fluid. A portable DEF tank with pump allows you to bring the fluid directly to the field, keeping your Tier 4 machinery running during critical operational windows without unnecessary downtime.
Construction & Excavation
Dirt, silica, and concrete dust are the enemies of Diesel Exhaust Fluid purity. Using a fully sealed Enduraplas Fuel Boss ensures that the harsh environment of an active job site never compromises your fluid quality, protecting your excavators and loaders from expensive injector failure caused by site contamination.
Mobile Fleet Maintenance
For mechanics running service trucks, bed space is valuable real estate. The compact footprint of our mobile 25 gallon DEF tank fits easily into a standard pickup bed or utility body, giving you a professional-grade dispensing CT system for roadside assistance without sacrificing the room you need for tools and parts.
Remote Power Generation
Backup generators at data centers, cell towers, or industrial sites often require servicing in hard-to-reach locations. With a reliable 12V DEF transfer pump and long-reach hose capabilities, you can easily access stationary equipment tanks without needing to maneuver heavy supply vehicles into tight spaces.
Forestry & Logging Operations
When you are miles deep in the timber, relying on disposable jugs is not a viable refueling strategy. You need a rugged DEF transfer tank built with high-density polyethylene that can withstand the shock and vibration of logging roads while keeping the pump mechanism fully shielded from branches and debris.
Municipal & Public Works
Snowplows, buses, and waste management trucks run on tight schedules and strict environmental budgets. Implementing a mobile DEF dispensing system ensures your maintenance crews can top off fleets quickly in the yard, utilizing the auto-shutoff nozzle to prevent costly and hazardous chemical spills on the asphalt.
