fuel vapor smell....

[Vegas~Blown]

for the past few weeks I'll get a strong whiff of fuel vapor on occasion after I shut my car off. It's not a raw fuel smell and it doesn't always happen --- but when it does the smell is very strong. the first time I noticed it I immediately checked the fuel connects at the engine and checked out the lines to the tank and didn't / don't see any fuel leaks. I got under the back a week or so ago and other than the rusted lines (that should be probably replaced) everything looked okay. It seems like right after a fill up and during hot days it's the worst.

Anyway, I smelled it today after I parked in the garage and popped the gas cap to see if there was pressure built up ---- there wasn't but what I heard was a bubbling sound, like high pressure air was being blown into the tank. It would "glub" a couple of times then wait a second or two and then repeat. It didn't seem like the strong fuel smell was coming from the tank --- but damn I can't pinpoint it either.

I replaced the solenoid within the past few years but don't know the evap system as well as I probably should so I'm not sure where to start looking. So if you can make heads or tails of this message I'd appreciate any ideas where to start looking.

thanks!

possibly have something to do with your spark plugs or even your exhaust/cat conv. ... maybe some un-burnt fuel is what your smelling? then again it might be alil more complex?

I'm interested in what this is too, I also sometimes have that smell coming from mine.

check the O ring on your fuel pump...it could b dry rotted...the reason i say this is because it happened to me.its accesible through the trunk...pull back carpet youll see a little plate that has a handful of screws open that and check there.
