Fuel Smell Inside Cabin
My questions are, has the MBUSA issued an recall for this issue? If not, what exactly needs to be replaced and how much will it cost? I can barely stand the smell any more and hate to even fill up my gas.

Any help is greatly appreciated!!




To be on the conservative side, start by removing the rear seat bench and take off the round cover that covers the sending unit. If you see gas on the unit, it could be the unit is leaking and needs to be changed. If gasoline is only on bottom of unit, it could be a bad seal which you could replace yourself if you're a handy person.

Frist, remove the bottom of the back seat, there are two tabs under the cushion that will allow you to remove it. You will then need to remove the access pannel that covers the sending unit, behind the driver's seat, which is round and has about 8 or so sheet metal screws in it, they're about 1/4 or 5/16 in size.
If you see gas puddling up on top of the sending unit, mine had about 3 cups worth, get it out of there...I used a shopvac, because there was too much to soak up with rags. Once it is dried up, see if you can tell where it's leaking from. If it's coming up from the bottom, it's more than likely the seals, if it's leading from up and behind (towards the back of the car) into the trough that the sending unit sits in, it's probably a cracked fuel tank.
If MB USA doesn't cover the cost of the fuel tank, like they did in my case, you'll end up spending $3K to fix this.
If your car is a PZEV, then dealer has to cover it under warranty.

Then I saw this:
Since it appears that no one mentioned it is a bad idea to suck fuel into a closed container, while mixing it very well with air, and topping off with a brush type AC motor; Maybe knowing not to do so is a special skill?

And thought, maybe I am wrong.

There is so much wrong with your comments about shopvac'ing up gas I don't even know where to begin. Maybe it's just best to ignore your comments for those who read that. Guess what? I still have all of my fingers, I'm not missing any eyebrows and my shopvac didn't blow up like a pressure cooker bomb
. HOW COULD THAT BE? I must have defied physics and chemistry in the alternate universe you live in. Before you give advice on a subject you might want to know something about it...just a suggestion.Anyways, the point of the subject, if you can determine where the leak is, roughly, coming from you can figure out if it's a cracked gas tank or if it is simply a fuel sending unit seal.
