Fuel Delivery and Air Induction: Service Precautions

WARNING: Adhere to the following procedures any time the fuel system is being worked on in order to reduce the risk of fire and personal injury:

^ Keep a dry chemical (Class B) fire extinguisher near the work area.
^ Place a "CAUTION FLAMMABLE" sign in the work area.
^ Work in a well-ventilated area. Do not smoke, and keep sparks and open flames away.
^ Wear eye protection.
^ Use caution when working near the catalytic converter to prevent the possibility of burns or fire. (The temperatures within the converter can exceed 537 degrees C (1000 degrees F).)
^ Relieve the fuel system pressure prior to disconnecting fuel system components.
^ Disconnect the negative battery cable except for tests where battery voltage is required.
^ Use a suitable container to store or catch fuel.
