Warning

•  Hot engines can cause severe burns. Be careful not to burn yourself during removal/installation of each component.

•  Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.

•  Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and damage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line Safety Procedure” when servicing the fuel system, and remove the fuel pump relay. (See BEFORE SERVICE PRECAUTION [MZ-CD 1.6 (Y6)].)
