Hello i got a problem with my mazda 2 from 2010.  It s a 1600 diesel from psa wich is also in volvo, ford , citroen and
peugeot.
When the car is stalled for two days it won't start.  When i losen the backflow pipe and pull it vacuum it starts immediatly.  So there must be a vacuum leak that the petrol flows back.
Somebody can give me a few good tips.
The low pressure pipeline set is not available for the moment and has to come from Japan.
Hope someone can help me.

Try installing a non-return valve on the fuel line.

After the fuel filter or where ??

Check the fuel supply line before the filter.
