What does this hose do?

Was tinkering in the engine bay of my car at the weekend and noticed that the rubber hose shown in the photo is a bit perished around the connection to the plastic connector and hard line. Hose is on the near side of the car behind the coolant reservoir.

Question: what does the hose do? And what is the part number for replacement? I've looked in the Porsche parts catalog but can't make out the right part.

Looks like your fuel line.

I agree, looks like the fuel line. On the turbo, that's where the fuel filter sits and the rubber hose is part of the filter, so you get a new one when it's changed. Not sure about the NA though.

Thanks for the replies. It goes into Northway for a 5k oil change on Monday so I'll get them to have a look.
