Fuel System Pressure Release
WARNING:
High fuel pressure may be present in fuel lines and component parts. Relieve pressure before opening system for testing or component replacement. DO NOT allow fuel to flow onto engine or electrical parts.
Disconnect negative battery terminal. Place container under fitting to be loosened. Use a rag to cover fuel line/component. Slowly loosen fitting, allowing pressurized fuel to spill into container. After fuel system pressure is released, disconnect and plug fitting.
