Gasoline fuel tanks on small passenger...

🔍 Key Concepts

• Fuel system safety requirements for small passenger vessels in 46 CFR (look at the sections on gasoline fuel systems) • How fuel shut-off valves are supposed to be arranged in relation to the tank and the engine • The difference between supporting/locating the tank and connecting it to the hull

💭 Think About

• Which option best reduces the risk of fuel leaking into the bilge or being siphoned out if a line fails? • Think about what would happen in rough seas or if the boat is heeled—how should the tank be mounted so it remains secure and safe? • Look at which option describes a structural installation requirement versus just a “nice-to-have” condition like being cool or higher than the engine.

✅ Before You Answer

• Verify in 46 CFR that gasoline tanks must be securely installed and supported to prevent movement or chafing. • Check whether regulations require a shutoff valve at the top or bottom of the tank, and why that matters for safety. • Confirm if the rules say anything about the tank being part of, or independent of, the hull structure.
