🔍 Key Concepts

• Gasoline fuel system safety requirements for small vessels • Risk of fuel leaks and vapors in bilges and engine spaces • USCG rules on fittings and openings in gasoline fuel lines

💭 Think About

• Ask yourself why regulators are strict about gasoline systems compared to diesel systems. • Think about what could happen if a valve or outlet in a pressurized fuel line failed or was left slightly open. • Consider whether routine tasks (draining, sampling, bleeding air) should be done from the main fuel line or from specially designed fittings/tanks.

✅ Before You Answer

• Check whether any extra openings/fittings in gasoline fuel lines increase the chance of leaks or vapor release. • Verify what USCG small vessel fuel system rules say about “drain cocks,” “petcocks,” or outlets” in gasoline lines. • Confirm whether the regulations favor eliminating potential leak points or adding more for convenience.
