Interesting Noises From Gas Tank

[Mistabullet]

Got out of the car (parked in garage) and smelled gasoline. Went to check the gas cap but it was tightly secured. After opening it I heard these funny noises. It was a mixture of hissing and what you would expect to hear if someone were to put a straw in the tank and slowly blow bubbles.

I'm not worried about it and I know it isn't a problem, but I am interested in figuring out what exactly is causing these noises.

O and this was after a nice healthy run with the V6 (I this engine)

You're car is having a BBQ in the tank. Get the buns!

Seems like when the car was new there was a tag hanging on the shift or somewhere close which explained that a pump would come on x minutes after the car parked to pressureize the tank/evacuate the tank. I don't remember which. Take a look at the stuff you stuck in the glove box and it will explain.

I know what your talking about gdanaher. If I remember correctly the tag said it would come on a few hours after you parked the car. But this happened RIGHT after I parked the car. But I guess it's possible it could be the same thing.

After some spirited driving I'm guessing the fuel vapor recovery system/EVAP system was having a hard time keeping up. I wouldn't sweat it.

FWIW - I think there is a TSB on the fuel vapor system, something with the charcoal canister?

On my SE-V6 I noted smelling STRONG odors of gasoline on a few occasions... I though maybe another car on the road was leaking gasoline but it happened on a few occasions and was really a STRONG odor... After getting rid of the car I think the TSB came out, I just figgured that was just another headache I didn't have to deal with.

Did you ever figure this out? I have an 07 camry 4cyl and it is making a hissing noise back by the tank as well, just started today.
