fuel leak.

[mountainman]

Been smelling gas around the boxster (03 S ) for a couple of days. aaaaaaaaaaapulled the battery out and removed the access plate above the tank and found fuel pooled on the top of the ring on top of the tank. It is leaking from the fitting on the end of the fuel line on the drivers side where it fits on to the top of the tank. No problem that I can see on the tank flange so appears to be the sealing ring inside the fuel line end fitting. I can't see where that line goes or how long it is since it disappears down along the drivers side of the tank. It soes not look like the sealing ring inside the fuel line is replaceable I assume changing that fuel line is the only fix. Anyone able to shed any light on what is involved in changing that line as in does the tank have to come out to access it and how far back does it go before there is a connection, etc. thanks
