Question 1934 Deck General

The correct answer is A) A shut-off valve. On small passenger vessels, the regulations require that a shut-off valve be fitted to the fuel line's tank connection. This is to allow the fuel supply to be quickly and easily shut off in case of an emergency, such as a fuel leak or fire. The shut-off valve provides a crucial safety feature to isolate the fuel source and mitigate potential hazards. The other options, while potentially useful, are not required by the regulations for the fuel line's tank connection on small passenger vessels. A fuel strainer (B) may be installed, but is not mandated, and a tubular glass gauge (C) is not a required component at the tank connection.
