Titan’s 30-gallon Spare Tire Auxiliary Fuel System repurposes the spare-tire area to add 30 gallons of diesel capacity for 2003–2012 Dodge/Ram 2500/3500 pickups with Cummins engines. The underbody tank includes mounting hardware, a universal filler kit, pump, valves and an electronic controller with an in-cab indicator and single-touch transfer. It preserves bed space, installs under the vehicle, and requires a Class V hitch.
