Assignment of connector couplings:
Note
The connector couplings for fuel, vacuum and breather lines are colour coded. There is either a coloured dot on the connector coupling or the release button is coloured.
Connector couplings for fuel lines must engage

WARNING
Fuel supply line is pressurised. Wear eye protection and protective clothing to avoid eye injuries and skin contact. Before loosening hose connections, wrap a cloth around the connection. Then release pressure by carefully pulling hose off connection.
Bear in mind that the fuel pump can be activated due to opening of a door with the battery connected. Fuel can escape if the system has been opened.
