Is it possible the fuel fumes catch system (whatever that is for the Porsche) could be failing and you are smelling that? I know many vehicles strongly warn about overfilling the car and I know there is a system to protect the environment by catching fumes from the tank. Could this system be compromised somehow?

Yes, I am taking it in to get a check out and switch out my fuel pump, venturi tubes and tank gaskets this coming Saturday.

 

Had this issue on my 996tt which did eventually pop a code. My issue was the fuel pump cap had cracked/melted from the wire having resistance the fuel pump is located under your front trunk might be worth a try to whiff around there when you smell the fuel.

i ended up cleaning the wires and using jb weld to fix the crack on the pump lid. Its been over a year without issue

 

Yeah I just recently replaced my fuel pump and venturi tubes along with the cap and sealing ring....only to find out after the fact that my manifold bolts had backed out a bit causing an exhaust leak (and gas smells).

 

[QUOTE=Porsche951S;2672567]I just got my 997 Turbo and notice sometimes when sitting at a light or slow cruise that the cabin fiills up with a strong smell of gas.. No lights have come on and its quite random but im still concerned.. Any ideas?
