I mentioned in an email to @Pottermus a little while back that I was getting a smell of petrol from my car after it has been sitting for a period of time. Today I got the jack out to find the source of the leak and it appears there is one on the fuel vent pipe. I had emailed him to see if the pipes are available of which he emailed back saying they where. However on closer inspection it appears that the plastic tray thing they sit in has come away from the body as well, since the plastic nuts securing them have gone bad from the last time they where taken off when the break lines where done years ago. While a fuel leak is of serious concern it is fortunately on a vent pipe only and I will be ordering a replacement part in due course. What is of immediate concern though is that the fuel lines are hanging down and this putting more stress on the old pipes. I will be ordering new clips so that they don't fall off and some additional ones for when the car goes in to get the pipe replaced.
