Volvo Repair: Fuel Leakage, volvo s60, 2001 volvo s60

Question
I have a 2001 Volvo S60, recently  I have noticed fuel(gasoline) on the ground when it is parked. I have also noticed a strong smell of fuel inside the car. I have had it checked by the  Volvo technician at a local retailer. Nothing appeared to be wrong with the fuel system. Pressure tested the system and it shows no leakage, but the problem still exist. I have not been over filling the tank. What do you suggest I do the solve the problem. It is most annoying, and possibly dangerous.  

Answer
depends where the leak is.if it is near the tank it may not show a pressure drop.it may be leaking from the fuel tank somewhere.I would have them check it again possibly by another technician.I have not seen this problem on the s60 so I could not say what it may be.
