Separating push-on couplings Assignment of push-on couplings   Note t  The push-on couplings for fuel, vacuum and breather lines are colour coded. There is either a coloured dot on the connector or the release button is coloured. t  Observe safety precautions → Chapter. t  Observe rules for cleanliness → Chapter.

Plug-in connector	Colour code on connector
Fuel supply	Black
Fuel return line	Blue colour
Breather	White, beige
Vacuum	green

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.

Version 1 Push-on coupling with release buttons -arrows- on right and left

Opening It is necessary to counterhold the separating point for fuel -1-. –  Insert -T10468- between heat shield and stop -arrow- of fuel line -2- and counterhold.

Continuation for all separating points of the fuel system. –  Push push-on coupling -1- in -direction of arrow A-. –  Press release buttons and pull push-on coupling -1- off fuel line -2- in -direction of arrow B-. Take note of colour assignment during installation → Anchor –  Ensure push-fit couplings are secured properly by pulling.

Version 2 Push-on coupling with pull-release mechanism -arrow-

Opening –  Push push-on coupling -1- in -direction of arrow A-. –  Pull pull-release mechanism -2- in -direction of arrow B-. –  Pull push-on coupling -1- off fuel line -3- in -direction of arrow B-. Take note of colour assignment during installation → Anchor –  Ensure push-fit couplings are secured properly by pulling.

Version 3 Push-on coupling with front button -arrow- Opening –  Press release button -arrow- and pull push-on connectors off. Take note of colour assignment during installation → Anchor –  Ensure push-fit couplings are secured properly by pulling.

Version 4 Push-on coupling with release buttons -arrows- on right and left Opening –  Press push-on coupling in -direction of arrow A-. –  Press release buttons -arrows- and pull push-on coupling off. Take note of colour assignment during installation → Anchor –  Ensure push-fit couplings are secured properly by pulling.

Version 5 Push-on coupling with release buttons -arrows- on right and left Opening –  Press release buttons -arrows- and pull push-on coupling off. Take note of colour assignment during installation → Anchor. –  Ensure push-fit couplings are secured properly by pulling.

Version 6 Push-on coupling with release buttons -arrows- on right and left Opening –  Push push-on coupling -1- in -direction of the arrow- and maintain pressure. –  Press release buttons -arrows- and pull push-on coupling off. Take note of colour assignment during installation → Anchor. –  Ensure push-fit couplings are secured properly by pulling.
