Q

How should gasoline tanks be filled?

🔍 Key Concepts

• Gasoline expansion with temperature and the need for an air/vapor space in the tank • Dangers of overfilling: fuel spilling into the boat, into the water, or onto hot surfaces • Goal of fueling: ensure safe operating range AND reduce fire/explosion risk

💭 Think About

• When gasoline warms up during the day, what happens to its volume if the tank is completely full with no air space? • Which option best balances having enough fuel for safe operation AND preventing spills or pressure buildup in the tank? • What are the fire and explosion risks if liquid gasoline, rather than just vapor, reaches vents or spills into the bilge?

✅ Before You Answer

• Check which choice allows some room for fuel expansion instead of a completely full tank • Eliminate any choice that would force gasoline out vents or filler openings as temperatures rise • Confirm that the option you choose still provides adequate fuel for normal safe operation, not just the bare minimum
