Fuel pipeline markings will be color coded according to which standard?

The correct answer is based on the established standard for identifying fuel pipelines through color coding. Military Standard (MIL-STD) - 161 provides the guidelines that dictate the specific colors to be used for various types of pipelines, including fuel lines. This color-coding system is crucial for safety and maintenance as it helps ensure that personnel can easily identify the type of pipeline and any hazards associated with it.

Understanding these standards is vital for anyone involved in fuel systems maintenance. Adhering to the color code not only promotes operational efficiency but also reduces the risk of accidents and errors during maintenance or operational procedures. The other options, while important in their respective contexts, do not specifically address the color coding of fuel pipelines. Thus, they would not be relevant to this specific question about pipeline markings.
