Fuel Smell

Loving my GS! But there's something bugging me.

I sometimes get a very strong smell of fuel in the cabin and boot (trunk). This seems to happen mostly when I have a full tank. The smell can be quite strong even when I haven't driven the car for a few days.

The fuel cap is tight and theres no visible signs of a leak. Someone mentioned that it could be the charcoal filter needing replacement - but I figure that might me responsible for fumes when the car is running, not when the car is off.

Any thoughts?

I recently had my fuel cell repaired after the technicians noticed a strong fuel smell (I have diminished olfactory senses - so I didn't notice). They performed a smoke test and discovered I had bought the car with a damaged fuel cell. Apparently, I was leaking fuel through cracks!

Here is what they (FM of V) stated on the invoice (total cost was close $4500):

GROSS EVAP LEAK FOUND.SMOKE TEST FUEL SYSTEM.FOUND R/S FUEL PUMP
CAP CRACKED (SIGNS OF FUEL LEAKING ON FUEL CELL). FOUND ONE FUEL ROLL
OVER VALVE LEAKING. HAD TO RE AND RE FUEL CELL. REMOVE SUB FRAME AND
TRANSMISSION ASSEMBLY. REPLACE R/S FUEL PUMP AND ALL SEALS AND ROLL
OVER VALVES.REPLACE FUEL FILLER GASKET. RE INSTALL ALL COMPONENTS AND
TORQUE TO FACTORY SPECS.ROAD TEST. NO MORE FUEL LEAKS FOUND AFTER
REPAIR.

Best bet is to have the dealership do a smoke test to be sure!
Hope yours isn't this bad!

Keep in mind also that I have a Spyder not a GS.
I believe (but not positive) the same job on your car would be a lot cheaper as I doubt you'd have to remove the transmission to get at your fuel cell if necessary.
Good luck!
