Probably won't get too many replies on this, but I'll try anyway...

I know I'm probably stupid for not ever looking into this, but ever since I got my car it always seemed to smell like gas. Especially, if it was in an enclosed area.

Now I know that it may be typical to smell a little like gas, but mine's significant. It's progressively gotten worse. My other cars didn't smell like this.

I'll probably bring into dealer. Just wanted to gets some ammo.

Anyone else experience this?

 

Possibly a leak in an evap line somewhere between tank and engine. Blocked return lines, etc. Usually that would set a check engine light though.

Best diagnosis would be to hook it up to a smoke machine for now, see if there are any obvious evap leaks.

 

not sure if this would help, but you could take off the rear seat cushion and see if it smells worse, since your gas tank is right there.

 

I had a small leak in the passenger side rubber hose between the front and back fuel rail that would make a pretty strong gas smell anytime i was stopped (not moving). So you could look there.

 

maybe see if there was an aftermarket system put in. One of my friends got a system installed at bestbuy, and they accidentally used the wrong screw and drilled a hole into the gastank while installing the amplifier. So mebbe theres a hole there from a botched installation of some sort. ?

 

Have you replaced any oxgen sensors lately? If you have not, the same thing happened to me. I smelled gas, within a few days the SES light came on, and 260.00 later I had to have a new oxygen sensor installed.

It gets worse though, once you replace 1 the other 3 go very quickly,

Good Luck

 

There is no fuel return line on his car or yours. Or are you speaking of something else?




Does the smell get worse when the tank is full? If so it's the cartridge seal on the fuel tank. The O ring needs to be replaced.

If not that then it's a severed fuel line or cracked fitting. And if it's under the hood of your car it's a ticking time bomb. Just tonight I saw the front end of a car engulfed in flames in a parking lot. Such engine fires are usually the result of a fuel leak under the hood.

Was referring to the evap. emissions system (LDP, purge valve, canister) and its related hoses. Not sure how Nissan implements it (I deal with Jeeps most of the time.)

 

Come to think of it... when you said that, I realized that it does seem to be after fill-up. I remember thinking (after fill-up) that it must be from the tires or my shoes that had contact w/ some gas.

Today, I filled up... It smells now. How can that be? Does this O-ring that you speak of, wear out? I've never heard of this...

SR20DEN, you've been a lot of help!

Thanks guyz for all the feedback!
