Abstract: A dual inlet fuel tank assembly for a vehicle and a method of using the same. The assembly includes at least one fuel tank, a first fuel inlet in fluid communication with the at least one fuel tank, and a second fuel inlet in fluid communication with the at least one fuel tank. A controller is in communication with the fuel tank and the first and second fuel inlets. The method includes providing a first and a second fuel inlet in communication with at least one fuel tank. At least one of the first and second fuel inlets is opened from a closed position. The vehicle is fueled through at least one of the first and second fuel inlets. Each opened fuel inlet is closed. Fuel inlet closure states for the first and second fuel inlets are determined. A safety protocol is initiated based on the determination of the fuel inlet closure states.
