Re: 164 Fuel Smell in Cabin
The two fuel lines that I've read about (and inspected) are the ones where the rigid pipes end, on the bulkhead, just above the steering rack. There are two short flexible sections that leak.
These are almost impossible to see from above with the engine in the car. Your best bet is to remove the rear section of the front-right-wheelarch liner. Somewhere behind the power steering pump, you will spot the two lines. Failure was a common weakness noted on the 164 Digest (old message board). I would inspect with a powerful LED torch, looking for traces of moisture.
The fuel lines to the fuel rail already mentioned are, of course, another culprit - and much easier to get to. AlfaLincs is certainly right about the fire risk. When I dropped in to see a retired fire-fighter friend of mine, he said "Mmmm - 164, these burn well, over-represented in vehicle fires considering the tiny number on the roads"...
