🔍 Key Concepts

• Duplex fuel strainer normal operating procedure • Maintaining continuous fuel supply to an engine underway • Risks of introducing air or debris into the fuel system

💭 Think About

• Think about why a duplex strainer has two sides and a transfer handle—what is it designed to let you do while underway? • Which action keeps the engine running while you deal with the clogged side safely? • Which choice could allow unfiltered fuel or air into the system and possibly damage or shut down the engine?

✅ Before You Answer

• Confirm which option maintains fuel flow and engine operation. • Eliminate any option that would send fuel around filtration directly to the engine. • Avoid any step that would suddenly stop fuel to the engine unless there is an emergency like fire.
