What must be done if fuel system components are replaced?

When fuel system components are replaced, it is crucial to test the entire system for leaks and performance to ensure proper operation. This step is essential because replacing one part of the system can affect the entire operation, and any new component may introduce inconsistencies or problems that were not present before.

Testing for leaks is particularly important in fuel systems due to the flammable nature of fuel and the potential for safety hazards. Additionally, assessing overall performance ensures that the new components are functioning correctly and that the system operates efficiently and effectively. Addressing the entire system rather than just the replaced part allows for a comprehensive evaluation, which is critical in maintaining safe and reliable fuel system operation.

By conducting thorough testing, any issues can be identified and rectified before the system is put back into service, mitigating risks and ensuring optimal performance.
