🔍 Key Concepts

• Basic requirements of a safe marine fuel system (USCG small vessel standards) • Difference between fuel containment (keeping fuel where it belongs) and engine performance (how well it runs) • Fire and explosion risks from fuel leaks and vapors in engine spaces

💭 Think About

• Which choice directly addresses preventing fuel leaks and dangerous vapors from escaping into the boat? • Which options are more about how efficiently the engine runs rather than whether the system is fundamentally safe? • If there were a small crack or loose fitting in the fuel system, which requirement would most clearly protect the vessel and crew?

✅ Before You Answer

• Identify which option focuses on leak and vapor control, not engine tuning or cooling. • Ask: Which requirement would the Coast Guard care about first for preventing fires/explosions? • Eliminate any answers that only improve engine performance but do not directly control fuel or vapor escape.
