When installing a rigid fuel line with a diameter of 1/2 inch, how often should it be supported?

Supporting a rigid fuel line properly is essential to prevent stress and potential failure due to vibrations or movement. The correct answer indicates that a 1/2 inch diameter rigid fuel line should be supported every 16 inches. This spacing ensures that the line is securely held in place to avoid sagging or excessive flexing, which could lead to leaks or structural damage over time.

In many regulatory standards and best practices, the recommendation of 16 inches for a 1/2 inch diameter line takes into account the mechanical integrity of the fuel line, ensuring it remains securely anchored while allowing for proper system operation. This level of support helps manage the stresses placed on the fuel line during flight, such as those caused by engine vibrations and aircraft maneuvering.

By adhering to this support guideline, technicians can help ensure both the safety and reliability of the fuel system, minimizing the risk of fuel leaks that could pose danger during operation.
