Description

The RDS auxiliary fuel tank is designed to feed the main fuel tank of your truck to increase driving range. It's an ideal option for fifth-wheel applications, providing the necessary clearance while adding extra fuel capacity. Manufactured in the U.S.A., these tanks meet DOT standards and include a manual sight gauge, internal baffles to reduce sloshing, and drain fittings. They are intended for use with diesel fuel, and compatible diesel install kits (Item #s 011025, 011029, and 011408) are sold separately. It features heavy-duty mounting tabs for secure installation, 100% pressure-tested and fully welded seams for strength and leak prevention, and rust-resistant aluminum construction.
