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 tubes or fuel system components, the fuel system pressure must be relieved. Failure to follow these instructions may result in personal injury.

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 fuel rail.
2. Remove the fuel injectors. Remove and discard the O-ring seals from the fuel injectors.







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

NOTE: Lubricate the new O-ring seals with clean engine oil before installing.

Install new O-ring seals on the fuel injectors.

4. To install, reverse the removal procedure.
