Titan’s 30-gallon Spare Tire Auxiliary Fuel System for 2001–2010 GM 2500/3500 Duramax pickups adds underbody diesel capacity and includes mounting hardware, filler kit, pump and an electronic controller for in-cab monitoring and one-touch transfers. The lightweight, cross-linked polyethylene tank installs below the bed so hauling space is unaffected and provides a practical reserve for extended range or heavy-duty use.
