Question 1 of 27070

On small passenger vessels, what type of devices are required at both the tank and engine connections of all internal combustion engine fuel lines?

🔍 Key Concepts

• Small passenger vessel fuel system safety requirements in 46 CFR • Purpose of safety fittings at the tank connection and at the engine connection • How to quickly isolate fuel in case of fire or fuel line failure

💭 Think About

• If a fuel hose failed or caught fire, which device from the list would most effectively stop fuel from feeding the fire? • Which option is specifically a safety control device, not just an inspection or maintenance feature? • Think about what the USCG wants at BOTH ends of a fuel line to control the fuel flow—what kind of device is that?

✅ Before You Answer

• Confirm which device’s main function is to start or stop fuel flow quickly • Eliminate items that are primarily for inspection, measurement, or draining, not emergency control • Remember the device must be located at both the tank and the engine connections of the fuel line
