🔍 Key Concepts

• Requirements for gasoline fuel systems on small passenger and recreational vessels (46 CFR and 33 CFR references—verify in current regs) • Purpose of a fuel tank vent: to safely release vapors away from ignition sources and enclosed spaces • Difference between enclosed compartments (like engine rooms or fuel tank spaces) and open/exposed locations on the hull

💭 Think About

• Which locations would allow gasoline vapors to collect in an enclosed area, and which would allow vapors to dissipate safely into the atmosphere? • Think about where ignition sources (engines, electrical equipment) are typically located—would you want the vent outlet near those areas? • Among the options, which choice best matches the idea of moving fumes to a place where they are least likely to accumulate and most likely to disperse?

✅ Before You Answer

• Eliminate any option where the vent terminates inside an enclosed compartment • Check that the chosen location allows vapors to escape to open air, not just to a different closed space • Confirm that the location minimizes the chance of vapors forming a flammable mixture near engines or electrical equipment
