🔍 Key Concepts

• 46 CFR Subchapter T requirements for fuel systems on small passenger vessels • Purpose and construction of flame screens on gasoline tank vents • Typical mesh size and material standards used to stop flame propagation in vents

💭 Think About

• Ask yourself: What is the primary danger a flame screen is designed to prevent in a gasoline vent line, and how does mesh size affect that? • Consider which options actually describe a screen that could reliably stop flame, versus dimensions or fittings that don’t directly relate to flame arresting. • Think about the environment around fuel tank vents: what material properties (corrosion resistance, openness, strength) are important there?

✅ Before You Answer

• Verify which choice actually specifies a mesh screen (not just size of pipe or louvers). • Check that the description includes a mesh count that is fine enough to arrest flame and is corrosion resistant for a marine environment. • Make sure the option you choose directly relates to the vent line flame screen itself, not to the fill pipe or general vent opening design.
