hi guys ! i have a problem you might be able to help me with ! i have a 97 buick lesabre 3800 v6 and when i drive my car and shut it off i smell gas fumes when i step out of the car ! i had it on the rack, checked all gas lines, fuel filter, gas tank and everything seems dry as a bone ! i just can,t seem to find out where the smell is coming from ! there are no gas leaks under the hood either and my check engine light is not on ! it don,t seem to hurt the running of the car any but i would like to get it fixed if anyway possible ! i would appreciate anything you can tell me ! thanks guys !

 

Could be a leaking fuel pressure regulator.
