Fuel Rail: Removal

WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Clean all fuel residue from the engine compartment. If not removed, fuel residue may ignite when the engine is returned to operation. Failure to follow this instruction may result in serious personal injury.
WARNING: Do not work on the fuel system until the pressure has been released and the engine has cooled. Fuel in the high-pressure fuel system is hot and under very high pressure. High-pressure fuel may cause cuts and contact with hot fuel may cause burns. Failure to follow these instructions may result in serious personal injury.
  1. Release the fuel system pressure. Refer to: Fuel System Pressure Release .
  2. Disconnect the battery. Refer to: Battery Disconnect and Connect .
  3. Remove the intake manifold. Refer to: Intake Manifold .
