Quick Release Coupling

Disconnect 

NOTE: When reusing liquid tube connectors, make sure to use compressed air to remove any foreign material from the connector retaining clip area before separating from the tube or damage to the tube or connector retaining clip may occur.
NOTE: Fuel injection equipment is manufactured to very precise tolerances and fine clearances. It is essential that absolute cleanliness is observed when working with these components or component damage may occur. Always install blanking plugs to any open orifices or tubes.
NOTE: Do not use any tools. The use of tools may cause a deformity in the clip components which may cause fuel leaks.
NOTE: Type 1 
    WARNING: Before beginning any service procedure in this service information, refer to Safety Warnings in SERVICE INFORMATION General Information. Failure to follow this instruction may result in serious personal injury.
  1. Refer to: Gasoline and Gasoline-Ethanol Fuel Systems Health and Safety Precautions  ( GASOLINE AND GASOLINE-ETHANOL FUEL SYSTEMS HEALTH AND SAFETY PRECAUTIONS ).
  2. If servicing a liquid fuel tube quick release coupling, release the fuel system pressure.

    Refer to: Fuel System Pressure Release  .

  3. Disconnect the battery ground cable.

    Refer to: Battery Cables - 2.0L Duratec-HE  ( BATTERY CABLES - 2.0L DURATEC-HE ).

    4. NOTE: When reusing liquid or vapor tube quick release couplings, make sure to use compressed air to remove any foreign material from the retaining clip area before disconnecting from the tube.
