Fuel Filler neck pipe

[Bigalham]

Hi recently purchased a 306 Cabriolet 2.0L 16v, with a know hood fault, but then discovered a few little niggles, so went into my local garage and today we discovered that the Fuel neck and rubber elbow pipe to the fuel tank needs replacing and car shouldn't be driven until it is fixed! 

The garage said they can get hold of the part and for us to source it.....hence me asking here...

I need to get some advice of the exact part and where to get one....

The garage suggested chekcing French sites.....?

Any ideas very welcome as this is our only form of transport atm.....

Thanks in advance
