X5017A6B is connected to which component?

• A. ATF3 lead generator T3
• B. APU fuel line
• C. Engine oil cooler
• D. Hydraulic reservoir

Answer: (B)

In maintenance diagrams, line identifiers tell you which system a particular line belongs to and where it runs. X5017A6B is a line tag that corresponds to a fuel pathway, specifically tied to the auxiliary power unit’s fuel supply. The APU fuel line connects the fuel system to the APU so it can start and run, so a tag like X5017A6B would naturally be associated with that route. The other options belong to different systems: a lead for a generator is electrical and would use electrical harness designators, while an engine oil cooler or a hydraulic reservoir are part of the oil and hydraulic systems and use their own respective line or component labeling. Always cross-reference the diagram to confirm the exact termination and routing, but the tag in question aligns with the APU fuel line.
