Should I worry about gas fumes igniting in my cabin? Think a cell phone could set this off or merely the electronics in the vehicle would be enough?

How do I identify the leak and fix this issue? Thank you

Must be leaking somewhere if you fear ignition Check this vid out for a little reassurance:http://dsc.discovery.com/videos/mythbusters-cell-phone-gas-station-minimyth.html

I get the smell when tank is full, but I've noticed if I take it easy through left turns until fuel level drops, it's not too bad.

You should worry a lot if the fumes are coming from the engine compartment. There is a line coming off the fuel rail that was recalled by Porsche, and the whole system is under a great deal of pressure. IMO, all rubber fuel lines in the engine compartment should be replaced.

Many 2.5s have burned to the ground due to fuel line failure.

Petrol fumes do have a fairly narrow range of concentrations they will ignite in. But it's not healthy for your lungs, never mind the chance of ignition.

I found that it's easy to overfill the fuel tank. If you do, the fuel is lapping at the vents in vapour system in the filler pipe. It's not supposed to do that. If you're used to filling to the third click on the bowser, teach yourself to stop at the first click in your 924.

Rasta - so with what should I replace the fuel line? Mine does indeed need the deed done.

If you know of a kit or can point us to a parts list....

Thanks.

Remember, the 924S is an early 944 with anorexia

I had the same gas smell problem in the cabin. My mech insalled a plastic cover from a newer 944 and sealed it off. No fumes in the cabin anymore. However, if I open the windows the fumes find their way in again... In my case there is gas dripping from the overflow pipe behind the back wheel even if the tank is only half full. This of course after spirited track driving or tight turns... Going to get a new bleeder valve installed. Lets see if that helps...

Sounds like a classic case of needing to drop the tank to replace all the fuel lines on top. You might even have a cracked tank; there's been some discussion about it.

Here's my saga (that includes links about the cracked tank)
