Regular stops to refuel can take their tole on your workday or extend your drive time on road trips with your 5th wheel trailer. Dee Zee Steel Auxiliary Transfer Tanks are tested and certified to hold diesel fuel for refueling equipment at the job site or for transferring directly to your truck’s fuel tank during longer commutes and storing tools of your trade.
Our tanks are constructed out of Heavy 14-Gauge Steel with radius curve design to eliminate key weld pressure points and are hydrostatically pressure tested up to 29psi to ensure they meet the highest level of quality. Our Auxiliary Tanks are protected by texture black NRT™ (No Rust Technology) rust inhibitor powder coat finish to help protect the box and keep it looking great for years.
