Hey Guys,
My car has always had a pretty bad fuel/exhaust smell, I just assumed it was from the high flow cats/old age etc. However it has gotten quite a bit worse over the last year or two and I've also noticed that the gas tank hisses loudly when I remove the cap.

I did some searching on the site and it looks like one of the probably causes is a crimped fuel return line to the charcoal canister. Does anyone else have any insight on this?

Thanks in advance!

Check the vent hose to your tank before anything. It may just be a matter of some crud, or a kink in the hose.

You'll have to crawl underneath. Worse case scenario, you'll have to drop one end of the tank to get to it.
