🔍 Key Concepts

• Backfire flame arrester purpose – what it protects against on small craft • Difference between gasoline and diesel fuel systems (fume characteristics, explosion risk) • Regulatory focus on inboard gasoline engines and carburetors/intake systems

💭 Think About

• Which type of fuel produces heavier-than-air vapors that can accumulate in the bilge and ignite from a backfire? • Do large vs. small engine size matter more, or does the type of fuel and intake system matter more for backfire protection? • Why are diesel engines generally treated differently from gasoline engines in explosion‑prevention rules?

✅ Before You Answer

• Identify which fuel type’s vapors are most likely to cause an explosive mixture in an enclosed engine space • Recall that a backfire flame arrester is installed on the engine air intake/carburetor – which engines typically have that setup? • Eliminate any option that focuses on engine size alone instead of the fuel type and vapor hazard
