WARNING:
- Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
- Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.

1. Release the fuel system pressure.
2. Remove the intake manifold.
3. Disconnect the fuel rail pressure and temperature sensor vacuum and electrical connectors.

6. CAUTION:
- Use an O-ring seal made of special fuel resistant material. Use of an ordinary O-ring seal may cause the fuel system to leak. Do not reuse the O-ring seal.
- Do not reuse the O-ring seal. Reusing an O-ring seal may cause the fuel system to leak.
