An auxiliary or transfer tank offers you extended fuel range and a variety of refueling options for your truck and equipment. A replacement fuel tank adds fuel capacity without taking up bed space or sacrificing ground clearance for a clean OEM look. An in-bed auxiliary fuel tank automatically fills your truck’s stock tank with computer controls. A transfer/refueling tank can carry and fill a variety of fluids including diesel, gasoline, kerosene or ethanol. If you want to save money on fuel, drive further, or refill other equipment – Manning has an option for you.
