Whut Stinks ??

1990 325 I convertible 5 speed. Any 1 know why every time I fill this car up, It smells like gas for the next 2 days.? At first I thought this was an isolated incident. But it has happened repeatedly for 4 months now.

Check the fuel line on drivers side just forward of left rear wheel. This is a molded hose and can develop a small crack and leak a few drops at a time. Good idea to look at all of the fuel lines from tank forward at this time.

Bear, good suggestion.
If no cracks are apparent, also be sure to check on top of the left side of the fuel tank where the fuel line connects to the tank. This area is notorious for rusting out where the metal hose fitting is connected to the tank, as there is a slight depression that collects water and corrodes enough to form a hole over time.
When the tank is full, the fuel will well up in to the depression. In fact, when my E30 was full and inadvertantly parked on a slight slope with the left side downhill, the fuel would actually puddle on the ground. In my case I had to
replace the fuel tank since the corrosion was so bad. (northeast car)
Hopefully you don't have the probelm this severe, as you will find the replacement procedure http://greg.scott.com/bmw/gastank.asp to be a barrel of fun.
