What is the minimum distance from a tank or fuel pump where the fuel supply line does not require coating?

The minimum distance from a tank or fuel pump where the fuel supply line does not require coating is established to maintain safety and protect the integrity of the fuel system. The correct answer is six inches.

This standard is in place because coating is intended to prevent corrosion and protect the fuel line from external damage. Within six inches of a tank or fuel pump, the risk of damage or leaks is heightened due to the proximity of equipment that can generate vibration, heat, or may be subject to physical impacts. Beyond six inches, the likelihood of these hazards diminishes, allowing for a safe assumption that the fuel supply line can remain uncoated without significantly increasing risk.

This standard reflects common practices in the industry aimed at ensuring the safety and proper functioning of fuel systems. Understanding these guidelines helps professionals effectively assess the necessary precautions required for different components and their locations.
