I'm getting a new service truck at work. It is a 2014 Chevy 3500 Cab & Chassis. It has a Duramax Diesel, and dual fuel tanks.
Where is the damned fuel tank selector switch? I've read the manual for an hour, and even called the 800 number in the manual, and no one seems to know. Other than the capacities section which lists capacity for front and rear tanks, there is no mention of the dual fuel tank system anywhere in that infernal book.
