WARNING:
- Do not smoke or carry lighted tobacco or 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 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. Remove the fuel rail.







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

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

NOTE: Lubricate the new O-ring seals with clean engine oil prior to installation.

To install, reverse the removal procedure.
- Install new fuel injector O-ring seals.
