At what pressure does a natural gas fueling nozzle operate?

Natural gas fueling nozzles typically operate at a pressure of around 3000 psi. This high pressure is necessary to enable the effective transfer of compressed natural gas (CNG) into vehicles designed for it. The high-pressure system ensures that a sufficient volume of gas can be stored in the vehicle fuel tank, allowing for longer range and more efficient combustion within the engine.

While the other options reflect high pressures, they are not standard for CNG fueling systems. The use of 3000 psi is a common industry standard that aligns with regulatory and safety requirements in fueling infrastructure for natural gas vehicles. This pressure level is designed to facilitate safe and efficient refueling processes while maintaining the integrity of the fueling systems.
