Fuel tanks shall be restrained to prevent movement of more than how many inches?

The correct response indicates that fuel tanks must be restrained to limit movement to no more than 1/4 inch. This requirement is crucial for ensuring safety and stability in marine applications. Excessive movement of fuel tanks can lead to various hazards, including potential leaks or disconnections from fuel lines, which could cause fires or environmental contamination.

Restraining fuel tanks effectively minimizes the risk of spillage and helps maintain the integrity of the entire fueling system, especially in the dynamic conditions found in marine environments, such as rough seas or sharp turns. These guidelines align with best practices in fuel system design and installation, aimed at promoting safety and compliance with industry standards.

Understanding this requirement highlights the importance of maintaining proper restraints for fuel tanks to ensure operational safety and adherence to regulatory standards effectively.
