🔍 Key Concepts

• 46 CFR Subchapter T requirements for fuel systems on small passenger vessels • Differences between gasoline and diesel fuel system fire risks • Material and connection type requirements for fuel line fittings

💭 Think About

• Which choice focuses on reducing sparks and corrosion in a gasoline system on a passenger vessel? • Look at which answers describe a connection type commonly approved for fuel lines, versus older or obsolete practices. • Think about what the Coast Guard wants to prevent in gasoline systems: fuel leaks, overheating, and ignition sources. Which option best addresses those?

✅ Before You Answer

• Verify which option specifies non-ferrous metal (less likely to spark or corrode in this use). • Check which fitting types (flare, flareless, soldered, interlocking) are typically recognized for high-integrity fuel connections in regulations and standards. • Confirm in 46 CFR that asbestos covering is not a current standard requirement for gasoline fuel line fittings.
