The document outlines the tasks, knowledge, and tools required for an automotive technician to perform diesel fuel system service. Specifically, it details 3 sub-tasks: 1) distinguishing the locations of diesel fuel system components, 2) ensuring the condition of the diesel fuel pipeline by checking for leaks and remedying any leakage, and 3) ensuring the condition of the diesel fuel filter by draining water, detaching and changing the filter, and bleeding the diesel fuel system. The technician must have knowledge of diesel fuel system components and operation, as well as the skills to locate components, check for leaks, and perform filter maintenance, using tools like service manuals, hand tools, flaring tools, and replacement parts.
