Yes, I know this is a 60 day old thread.   I had the exact same problem with my 95 2.5.   I looked and smelled everything. Removed the fuel tank.  Could not find the problem.   So i took out the Fuel Pressure Regulator.  The small O-Ring had a pretty good rip in it,   i must have done it when last installed. 
 Went to the local Hardware store and found the one i needed.  put some grease on the o-ring and installed it.  NOW,  no more smell and it runs alot better.   I hope this can help somebody.
