There is advice there regarding fitting cable ties to the quick release connectors on the petrol lines
Perhaps something to check this weekend
Here are a couple of photo's to help you identify the connectors
From the boot, remove the inspection cover. On the passenger side you should be able to see the fuel filter and this orange connector.
and to the right slightly lower this green connector
These are the connector indicated in the diagram.
To release the connector you have to push the black collar into the coloured section. To prevent this from happening accidentally it is suggested to put a cable tie on the black section such that it cannot be pushed in.
