Just took the gas tank down for the 2nd time(bad o-ring didn't seal leaked gas). I used a new o-ring and put in a new pump this time also added a little sealant to make sure it doesn't leak. Everything seams ok but when I take the cap off after driving it around, still don't hear the "pressure release" like I did on my other camaro. Is anything wrong hear?

 

thirdgens don't use a vented fuel system, it's normal to hear a swish sound when you remove the cap

 

So is it bad that I don't hear this now?
