General Procedures - Quick-Connect Fitting
Disconnect
NOTICE: When reusing fluid or vapor tube connections, always 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 clip may occur.
NOTICE: Fuel injection equipment is manufactured to very high tolerances and fine clearances. It is important that absolute cleanliness is observed when working on these components or damage to the component may occur. Always install plugs on any open holes or pipes.
NOTICE: Do not use any tools. Use of tools may deform the retaining clip components, which may result in fuel leakage.
- When servicing a quick-connect fitting on a fuel liquid tube, relieve the fuel system pressure.
Refer to: Fuel System Pressure Release (310-00C). - Disconnect the battery ground cable.
