Ok, so my RX-7 was running fine, until last night I filled it up, now when I'm driving all I can smell is gas in the inside of my car, it's really concerning me, any tips on what it could be, on what I could do to get rid of it?

 

check to make sure the gas cap is on tight. gas will flow out the fill neck when making right turns.

 

First time you have filled it up? Might be pin holes on top of the tank its pretty common.

 

Dont light a cigarette
man start at the front and work your way back
to the tank be sure to check the return lines and make sure they arnt clogged up
your just gonna have to check everything fuel related i hate it for ya

I had a similar problem, I had pin holes just like yetterben said above, AND my sending unit was leaking around the seal.
