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?

Finally got my hands in fuel pumps in my 04 Spyder. The right side pump is under the metal cover and sure enough there is a leak and those 4 "pies" on top of the pump are filled with gas, as described earlier in this thread by jscriscuolo. I wonder if his glue has held all the way to this day. I will send a PM as well to check.

Received my new pump in number of days, ordered from UK website and product was shipped directly from Latvia by TNT, so it was fast. Total cost around $150.

I was going to change it right away, but noticed that the epoxy I had used to stop the leak has somehow miraculously cured the leak. When I applied it and tested the following day after applying it, fuel was still leaking. After sitting for about a week, not using the car it was just fine, no leak at all! Very strange, but that is still the situation after several days. Planning to put in the new pump but kind of qurious to see if that epoxy just keep holding for another few days. Obviously, it will give you a termporary fix, just be patient before using your car, at least few days. 24 hours was not enough.

My new pump is Bosch 0 580 313 104, and that level sensor was very easy to remove. Ready to go in and now I have a spare sensor.

Coming back to this thread. I should have ordered 2 pumps, not my other pump is leaking as well. Same place, the "pietray". Well since I know now it is not a big job, even though this left side pumps has a bit more work (right side is really easy), time to order a new one.
So, just ordered a new one from the same place, uk website, product comes from Latvia. Should be at my door in Florida in 3-4 days.

BTW: had good success repairing a metal tank of another car with Plastic Padding Leak Fix, this was in Europe.
