Removal and Installation

WARNING:
- Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel-related components. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in personal injury.
- Fuel in the fuel system remains under high pressure even when the engine is not running. Before working on or disconnecting any of the fuel lines or fuel system components, the fuel system pressure must be relieved. Failure to follow these instructions may result in 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.
4. Remove the bolts and the fuel rail pressure and temperature sensor.
- To install, tighten to 6 Nm (53 lb-in).

5. Remove and discard the O-ring seal.

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

To install, reverse the removal procedure.
- Lubricate the new O-ring seal with clean engine oil.
