When installing a 1/2 inch diameter rigid fuel line, what is the recommended support interval?

The recommended support interval for a 1/2 inch diameter rigid fuel line is 16 inches. This specification is crucial for ensuring that the fuel line is adequately supported and secured to prevent vibration, movement, or potential damage during operation. Proper support helps mitigate stress on joints and fittings, which can lead to leaks or failures in the fuel delivery system.

In practice, supporting the fuel line at this interval offers a balance between maintaining flexibility for the line while preventing sagging or excessive bending that could compromise the fuel flow. It also facilitates installation and maintenance, as rigid lines need to be secured in a way that allows them to expand and contract with temperature changes without being overstressed.

Failing to adhere to this recommended interval may result in mechanical issues, excessive wear, or interference with other systems in the aircraft, emphasizing the importance of following established guidelines for fuel systems.
