Fuel Pump: 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.


WARNING: Fuel line spills and leaks 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 Procedures".
