02GT..had CEL checked at advanced auto and said that I had a small evap fuel leak... and to replace my gas cap... replaced it... reset code, and came back after a day a driving... I smell fuel in my interior when driving, mostly when making left hand turns..... do you think this is my fuel filler neck gasket? I haven't noticed any leaks, but then again I didn't know to look there... and my tank is never past the 1/2 mark
.....I'm one of those wait until the light comes on and throw $20 bucks in...

What the exact code?

The leak could be anywhere from the gas tank through the vac line that runs from the tank to the passenger side of the engine. There is a serious of solenoids and valves involved. Any of these can be leaking and seeping into the passenger comparment.

What's usually done is a smoke test to find the source of the leak.

Gas cap usually displays as a "large" EVAP leak, not a small one. I wouldn't go changing the fuel filler gasket just yet
