What is the fuel delivery system? The fuel delivery system is one of the most critical components in a vehicle and is the heart of a vehicle's power generation process. The fuel delivery system serves a similar function to a fuel tank in diesel-powered vehicles. However, the fuel delivery system is specifically designed to handle gaseous fuels like hydrogen and natural gas, both of which are stored at high pressures. 

Natural gas powers more than 175,000 vehicles in the United States and 23 million vehicles worldwide. It’s an ideal alternative to gasoline and diesel for heavy and medium-duty applications. These include freight-hauling trucks, buses, and garbage trucks. Natural gas engines provide horsepower, acceleration, and cruise speed comparable to conventional fossil fuel engines. This fuel can also replace gasoline in smaller applications, such as forklifts and commercial lawn equipment.
