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.
- Do not replace fuel pipe with fuel hose.
- Plug all disconnected fuel line fittings and hoses.
- After making any fuel system repairs ALWAYS inspect for fuel leaks.

CAUTION

- Wear work clothing, including a cap, protective goggles and protective shoes during operation.
- Remove contamination including dirt and corrosion before removal, installation or disassembly.
- Keep the disassembled parts in order and protect them from dust and dirt.
- Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, installation, disassembly and replacement.
- Be careful not to burn yourself, because each part on the vehicle is hot after running.
- Be sure to tighten fasteners including bolts and nuts to the specified torque.
- Place shop jacks or rigid racks at the specified points.
- Before disconnecting electrical connectors of sensors or units, be sure to disconnect the ground cable from battery.
- Place "NO FIRE" signs near the working area.
- Be careful not to spill fuel on the floor.
