When the vehicle is running on gasoline, the CNG tank is sealed off and the gasoline fuel pump draws fuel from the gasoline tank and sends it to the engine. When the driver switches to CNG, the gasoline fuel pump is turned off and the CNG solenoid valve is opened, allowing CNG to flow from the CNG tank to the engine.
The fuel selector switch is typically located on the dashboard or center console of the vehicle. It has three positions: "gasoline," "CNG," and "off." When the switch is in the "gasoline" position, the vehicle will run on gasoline. When the switch is in the "CNG" position, the vehicle will run on CNG. When the switch is in the "off" position, the fuel supply to the engine is shut off.
The Chevy dual fuel tank system is a convenient way to save money on fuel costs, as CNG is typically cheaper than gasoline. It also reduces emissions, as CNG burns cleaner than gasoline.
