🔍 Key Concepts

• 46 CFR Subchapter T requirements for fuel systems on small passenger vessels • Purpose of fuel shut-off valves in preventing fuel-fed fires • Difference between requirements for fuel supply lines versus fill and vent lines

💭 Think About

• Think about where you would need to stop the flow of fuel quickly if there were a fire in or near the engine. • Consider whether the regulation is designed to protect only the tank, only the engine, or both parts of the system. • Ask yourself which options mention the actual fuel supply line versus parts of the system that only handle fuel during filling or venting.

✅ Before You Answer

• Verify in 46 CFR Part 182, Subpart J – Piping Systems and Fittings for specific language on fuel shut-off valves. • Check which answer choices clearly refer to the fuel supply line and not just fill or vent piping. • Confirm whether regulations require isolation of the fuel at more than one point in the supply path for safety.
