1. A method of operating a reserve fuel system including a reserve fuel tank retention and control (RTRC) module, the method comprising:
mounting the RTRC module onto a main fuel tank such that a longitudinal axis of a reserve fuel tank of the RTRC module is parallel to a longitudinal axis of the main fuel tank, the main fuel tank being operatively coupled to an exterior surface of a vehicle such that the longitudinal axis of the main fuel tank is positioned parallel to the ground surface upon which the vehicle is to be operated on;
fluidly connecting the RTRC module to the engine and to the main fuel tank;
actuating a valve of the RTRC module to a first position to allow fuel to flow from main fuel tank to the engine; and
upon detecting that the main fuel tank is empty, actuating the valve to a second position allow fuel from the reserve fuel tank to supply the engine.
