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.

CAUTION: If used as a leverage device, the fuel rail may be damaged. Care must be taken when working around the fuel rail.

NOTE: During the repair or replacement of fuel-related components, all liquid and vapor fuel openings shall be capped, taped or otherwise appropriately protected to prevent the ingress of dirt or other contamination. All caps, tape and other protective materials shall be removed prior to installation.

1. Remove the intake manifold.
2. Disconnect the spring lock coupling.
3. Remove the fuel supply tube bracket bolt.
- To install, tighten to 8 Nm (71 lb-in).

4. Disconnect the fuel injector electrical connectors.
5. Disconnect the fuel pressure and temperature sensor electrical and vacuum connectors.
6. Remove the bolts and the fuel rail and injectors as an assembly.
- To install, tighten to 23 Nm (17 lb-ft).

7. CAUTION: O-ring seals are made of special fuel-resistant material. Use of ordinary O-ring seals can cause the fuel system to leak. Do not reuse O-ring seals.

To install, reverse the removal procedure.
