In search of the source of a strong smell of petrol that can be smelt at the rear of the vehicle after completing a journey, i.e. only when the engine has been running, I find a small tube is attached at one end only to the end of the breather tube NTC2787 that is attached just below the filler neck.
I think it is part 575865 although it is much shorter than one would expect from the parts manual. It's about 3 or 4 inches long.
The pipe is clear reinforced polythene and has some sort of tapped insert in the free end.
I can see lots of pretty pictures of the non-evaporative loss system in the parts book but can't relate it to the fuel filler plumbing. Nor can I find any information about how to get to it. 'Off comes the wing' seem to be the most likely answer but, obviously, I do not want to do that without good reason.
So, where should the pipe go and/or what is it?
VIN is 3GA4..
TIA
