Hello.

I have a Fabia 1.4 MPI 50kw (engine code AME). While doing regular car work/inspection, I noticed that the excess fuel return line has been removed. Having researched online, I've found out it should be a blue hose leading from the charcoal filter to the fuel pressure regulator. But in my car, there is no hose around the pressure regulator, and from the charcoal filter there is about 50cm of a black hose which was sealed off at the end using a bolt and a hose clamp. I'm wondering why someone would remove the fuel return line, and if there are any problems that this would cause, as my car has a few issues that could be fuel/air related.

I appreciate any helpful advice/insights.

It may be that they had a fault/leak in the evap system and just removed it and blanked the pipe. Not sure if its actually needed. I believe its to do with emissions/fuel vapour etc. Non of my old cars had evap.
