Question 1 of 27070

On small passenger vessels, fuel lines are required to be made of which material(s)?

🔍 Key Concepts

• Fuel system construction requirements for small passenger vessels in 46 CFR Subchapter T • Which metals are commonly used and approved for fuel lines carrying gasoline or diesel • Differences between tubing materials vs. pipe/fittings (e.g., annealed copper vs. galvanized iron or plastic)

💭 Think About

• Look at which option lists materials that are specifically described in the regulations for fuel supply lines on inspected small passenger vessels • Ask yourself which of these materials would be safest and most resistant to corrosion and failure when carrying fuel under pressure and vibration at sea • Eliminate any materials that are generally prohibited in fuel systems, such as those that can crack, melt, or flake internally

✅ Before You Answer

• Verify in 46 CFR Subchapter T what materials are permitted for fuel distribution lines and fittings on small passenger vessels • Check whether plastic or galvanized iron are allowed or restricted in fuel supply systems on inspected vessels • Confirm that the correct choice refers to annealed seamless tubing of specific copper‑based alloys that are recognized in the regulations
