2004 Volvo S80 6 cyl Two Wheel Drive Automatic 86,000 miles
When I park my vehicle after driving, I smell a very strong odor of gasoline. I have sniffed under the hood, checked my fuel cap (it's tight), and looked for wet spots near the gas tank and on the ground. It just passed an emissions test yesterday.
Remove the rear seat cusion and rear passenger backrest. To access the 15mm bolt holding the backrest you need to remove the side padding but it will be pretty dificult to remove and a good chance you will break at least one of the locking clips. Once you have removed all that lift up the carpet padding and there is a cover with 4 10mm nuts. Remove the nuts to remove the cover. Now you have access to the fuel pump and that is where most likely your leak is coming from and strong fuel odor as well. I recommend you take it in to a shop for this repair if it is leaking. Good luck and let me know what happens.
