Question

9 multiple choice 1 point which is the preferred cleaner for modern fuel system components? brake cleaner electrical contact cleaner liquid varsol diesel fuel 10 multiple choice 1 point shutting down a engine in a run - away condition will require the technician to turn off the ignition disconnect fuel supply choke off air supply stall with transmission 11 multiple choice 1 point how often must a fire extinguisher be inspected by a registered specialist? annually quarterly monthly

Explanation:

• For question 9, diesel fuel is often used as a cleaner for modern fuel - system components as it can help dissolve contaminants without causing damage. Brake cleaner is for brakes, electrical contact cleaner for electrical parts, and liquid varsol is not a typical fuel - system cleaner.
• For question 10, in a runaway engine condition, choking off the air supply is the most effective way to stop the engine as combustion requires air. Turning off the ignition may not work in a runaway situation, disconnecting fuel supply might not be immediate enough, and stalling with transmission is not a reliable primary method.
• For question 11, fire extinguishers are typically inspected by a registered specialist annually to ensure they are in proper working condition.

Answer:

1. Diesel fuel
2. Choke off air supply
3. Annually
