Which component must be inspected as part of the liquid fuel leak inspection?

• A. Distributor cap
• B. Charcoal canister
• C. Coolant reservoir
• D. Seat belt buckle

Answer: (B)

Focus on the evaporative emission control system and its vulnerability to leaks. The liquid fuel leak inspection checks components that handle fuel vapors and any liquid fuel that could escape into the atmosphere. The charcoal canister is a key part of that system, capturing fuel vapors from the fuel system and routing them to the engine. If the canister or its connections are damaged, you can see wet spots, spills, or smell gasoline, signaling a leak. The other items listed don’t participate in the liquid fuel leak path: the distributor cap is part of the ignition system, the coolant reservoir is part of the cooling system, and the seat belt buckle is unrelated to fuel leaks. So the charcoal canister is the component that must be inspected for liquid fuel leaks.
