Question

Quizplus · Accepted Answer

Technician A is correct because a flare nut wrench, with its design missing two sides, is specifically made to grip the softer metals of fuel and brake lines without stripping them, providing a better grip than standard wrenches for these applications. Technician B is incorrect because a box-end wrench, while offering a good grip, is not as suitable as a flare nut wrench for fuel and brake lines due to the potential for damage to the lines.
