During refueling, what should you do with the fuel nozzle?

• A. Remove nozzle quickly after starting
• B. Spray fuel across the deck
• C. Keep fuel nozzle in contact with the opening
• D. Use only if the engine is running

Answer: (C)

Grounding the fueling system is the key idea. Keep the fuel nozzle in contact with the filler opening so there’s a continuous electrical path to ground. This prevents static buildup from reaching a spark, which could ignite flammable vapors on board. Lifting the nozzle away can allow a static discharge, so avoid that. That’s why spraying fuel around the deck is dangerous and fueling with the engine running isn't appropriate. Always ground the system and follow safe fueling practices, including turning the engine off before refueling.
