🔍 Key Concepts

• Trace the piping on illustration MO-0058 from each labeled pump to see where it actually discharges. • Recall the normal flow path in a diesel plant: storage tank → settling tank → service tank → booster/injection system. • Understand the different functions: transfer moves fuel between tanks, booster feeds the engine, purifier/centrifuge cleans fuel and often returns it to service or storage tanks.

💭 Think About

• On the diagram, which pump has a discharge line that is explicitly labeled as going to (or "from") the settling tanks? • Does the booster pump piping go back toward the tanks, or does it head toward the heaters/filters and then the main engine? • Would an auxiliary bilge pump normally be part of a fuel oil transfer line, or part of a separate bilge/waste system?

✅ Before You Answer

• Verify which label appears directly above the settling tanks (look for text like "From ... Pump"). • Confirm that the pump you choose is shown upstream of the purifiers and booster pumps, not downstream feeding the main engine. • Make sure the chosen pump is part of the fuel transfer system, not the bilge or purifier discharge/waste system.
