Explanation:
Both Technician A and B are partially correct.
Technician A is correct in saying that common rail fuel systems are known for their high fuel efficiency. Common rail fuel systems allow for more precise control over fuel injection, resulting in better fuel atomization and combustion efficiency.
Technician B is also correct in saying that common rail systems are more complex and require more maintenance than traditional mechanical fuel injection systems. Common rail systems have more components and electronics, which can lead to more potential points of failure and require specialized equipment for proper diagnosis and repair.
