Subaru Wagon Fuel System problems by year

With onset of cold weather (less than 25 f) this year, my 2002 suburu outback station wagon (2.5 Litre) has a strong gasoline odor in the cabin when engine is started. It happens every time now. It is very strong and there seems to be a fuel leak in the engine compartment. I'm concerned that it could cause a fire (particularly in conjunction with an accident or exhaust problem) or a fume related blackout of somebody in the car. I have read on the online discussion that this is a very common problem with suburus...

Whenever the temperature drops significantly (e.G. Below 32deg), a strong gasoline smell is emitted from the car upon starting. It eventually seems to go away over 10-30min, but it can be extremely strong. We just encountered the problem today (the coldest day in allentown this winter), but when we had the problem last year, the dealer was unable to identify any clear cause. They also claimed that they could not reproduce the smell.*Cn

My car will startup just fine. Upon near a standstill at a light or stop sign it will hestitate or stall completely. I have to keep my left foot on the brake and the right foot on the gas pedal to keep it going. This seems to happen more frequently in colder than hotter weather. I have had this vehicle at vanbortel subaru on 11/1 and they released it back to me on 11/3/04 saying the problem was fixed. Its anything but fixed and in fact gotten worse.*Ak
