Fuel Delivery and Air Induction: Service Precautions
Precautions for Fuel System ServiceWARNING:
Before servicing on fuel system, the following points should be always observed in order to reduce the risk of fire and personal injury.
- Disconnect negative (-) cable at battery.
- Do not smoke, and place no smoking signs near working area.
- Be sure to have CO2 fire extinguisher handy.
- Be sure to perform work in a well-ventilated area and away from any open flames (such as gas hot heater).
- Wear safety glasses.
- To relieve fuel vapor pressure in fuel tank, remove fuel filler cap from fuel filler neck and then reinstall it.
- As fuel feed line is still under high fuel pressure even after stopping engine, loosening or disconnecting fuel feed line directly may cause dangerous spout of fuel. Before loosening or disconnecting fuel feed line, make sure to relieve fuel pressure.
- A small amount of fuel may be released when the fuel line is disconnected. In order to reduce the risk of personal injury, cover the fitting to be disconnected with shop cloth.
- Never perform service work when engine and exhaust system are hot.
CAUTION:
- Use the unleaded fuel only.
- The leaded or low lead fuel can result in engine damage and reduce the effectiveness of the emission control system.
