Hi guys, just thought I would post about the problem that I have been chasing. My 07 G had started smelling like gas inside at idle last Saturday. I had just filled it up about a day prior so I thought it may be the evap system but after doing some checking I found that if that was the case I should have an evap code so I looked elsewhere. I checked under the hood and found gas seeping from what I thought was the o-ring at the fuel Damper. There are three Dampers on mine. One on each fuel rail and one at the end of the fuel line coming from the fuel tank. The one that was leaking was the one on the end of the fuel line. I replaced the o-ring and thought it was fixed but I kept smelling gas at idle. Im not going threw what all I checked but what I found was that the Fuel Damper was actually leaking randomly around what looks like the little hat area. So once I replace the 90 dollar fuel damper and washed the motor down so I would not have the residual gas smell it seems like all is well. I just wanted to let you guys know about this because I searched all over the net for info on this problem and found nothing. So, thanks and I hope this keeps others from going threw what I have!!!

 

Thanks for your contribution.

 

I'm having the same issue with my 07. Here's a pic for anyone that's curious what the part looks like.

 

Love this forum! I'm having the same issue. I see a little bit of fuel along the bottom of the fuel damper assembly. Not enough to leak and drip on anything, but definitely enough to smell! Where did you get the damper from? Dealer? Or elsewhere? Thanks!

 

hmm mine does smell a little when i start it up but then goes away. If the fuel damper is bad, would it always be smelling?

 

Well, if the pic of what Frankenstien posted is a fuel damper, then thats where my leak is - along the bottom. There is another thread that talks about this, too. Its at warm idle. And it hits me like a ton of bricks when I get out of the car after I park it in the garage.

 

Hey guys - mine didn't smell all the time and for more than a year I was only getting an intermittent oil-burning smell, usually on really cold days. After discovering this leak, I noticed that the gas had been dripping down the engine and leaving an oily film so I assume that's what was causing the burning smell. I think it just wasn't leaking fast enough to smell it in the cabin at first. Eventually it started getting worse and I was able to track it down with the help of this thread. Even when it was bad enough to smell, it wasn't all the time and was typically the worst within 10 minutes of starting it in the morning.

I got the part from http://infiniti.sewellparts.com/ They have two options for the 2007 sedan, depending on the specific manufacture date of the vehicle.

 

So my guess is that its either 22675JK20A or 22675JK20B, correct?

 

Yep! Check you vehicle against the production dates listed under each part #.

 

Seriously asked this question last year no one had any idea!!! Thanks !!!

 

Awesome! Part is on its way! Looks like it wont be too difficult to replace either - at least I hope so! Thanks Frankenstein!!

 

I was able to do the swap without getting under the car at all. Here are a few things I learned along the way.

1. I took out the passenger side air box. this was super easy and gave me a ton of extra room to work.

2. between you and the end of the damper assy is a metal bracket that obstructs your view. I removed this, but in hindsight I don't think it was necessary but I had no idea how the assy was secured to the fuel line back there.

3. There is a green clip securing the assy to the fuel line. It is cylindrical and maybe 2" long, and open on one side. I spent quite a bit of time trying to poke around for some sort of release or something, but the whole thing just comes off if you pull away from the open side. If you look at the clip from the end, it kind of looks like a C <- open side.

 

I've had the same issue, just an occasional waft of gas at idle. Thanks- I will check this out.

 

Thank you for this post. I have also smelled gas when the car is warmed up and idling. I have only noticed it during winter.

I took a look and sure enough there is a wet spot under the fuel damper that smells like old gas. This would have been a real hassle to find if I didn't know where to start looking.

 

Welp, I finally got under the hood to replace my fuel damper assembly last night and it turns out I got the wrong part. The stiff hose is too long and the connector at the end has a 90 degree elbow on it whereas the one on there now is a straight connector. Also, Frankenstein, I didn't see the things you mentioned (which, btw, I very much appreciated!). I wonder if we're talking about the same damper. Mine is on the front, passenger side and runs down from the "hat"-looking part at about a 45 degree angle. I couldn't quite get my hand down in there to release the clip, which was not green nor cylindrical, nor 2" long.
Also, my G is a 2007 assembled in August of 2007.
Thanks!
