I also have a 2004 XC90 and a couple of months ago I had the exact same probelm... after multiple visits to my dealer's auto shop they figured out that it was the fuel pump. They replaced the fule pump and the smell disappeared. Good luck!

SOURCE: Gas line is leaking.
You want to be very careful not to make any sparks while working on this. The obvious is smoking, banging metal tools around, etc. keep cell phones AWAY from the area. Pick up some rubber fuel line from the parts store. Be prepared for some gas leakage, have a plastic pan under the leak. Disconnect the line at the tank, have a piece of new hose ready to push on over the line to as close to the tank as you can, have the end away from the tank plugged up temporarily with a pencil or something that fits snug in it, then remove the rubber hose on the filter, and connect new line from tank to filter, check for leaks, hopefully it is the rubber line you replaced, or the end of the metal line, so the new hose will hopefully cover the corroded leaking area. Clamp and Dry off area and see if you can spot any leaks.

The Lines are simple if it's a 2.4 EFI the lines run on the driver side inner rail from the center top of fuel tank, and up the middle of the firewall to the injector rail or throttle body carburetor there is also one line that runs from the evap canister back to the tank and to the fuel system three lines total one is a return line the large line is the main fuel line and has the fuel filter mounted on it and is under the driver side door inside the frame rail.
