What colors should portable gasoline and diesel fuel tanks be respectively?

Portable fuel tanks are color-coded to enhance safety and minimize the risk of accidents related to fuel misidentification. According to industry standards, portable gasoline fuel tanks should be red, while diesel fuel tanks should be yellow.

The reason red is designated for gasoline is to align with common safety practices and to provide a clear visual indicator that distinguishes gasoline from other types of fuel. This standard helps prevent confusion, especially in situations where multiple fuel types may be present.

For diesel, the use of yellow as the color code serves a similar purpose. It offers a distinct visual cue that indicates the tank contains diesel fuel, thereby reducing the chances of mistakenly filling a diesel engine with gasoline, which could lead to significant engine damage.

Using these specific colors—red for gasoline and yellow for diesel—improves safety protocols in handling and transporting fuel, making it easier for users to quickly identify the fuel type and take appropriate safety measures. This system is widely recognized in the marine industry and other sectors where fuel safety is critical.
