🔍 Key Concepts

• 46 CFR requirements for gasoline fuel systems on small passenger vessels • Design and location of fuel fill pipes and deck fittings • Safety concerns about gasoline vapors in enclosed spaces

💭 Think About

• Think about why regulations are strict for gasoline versus diesel on small vessels. What specific hazard are they trying to minimize? • Look at each option and ask: does this address a different part of safe fuel filling (location, closure, and containment of spills/vapors)? • Consider whether the regulations typically require just one of these features, or a combination working together for safety.

✅ Before You Answer

• Verify in 46 CFR that a gasoline fill pipe must terminate on the weather deck and how close it must extend to the bottom of the tank. • Check whether a marked, watertight deck plate or screw cap is required at the fill point. • Confirm if the system must be arranged so that neither liquid gasoline nor vapors can escape inside the vessel during filling.
