Here is a picture from my completed removal project. In the future, I will probably remove the two blocked vent lines, but kept them in there for now - keep it simple
I pulled everything out and just let the tank vent to atmosphere under the liner - you can see the vent line attached to the metal bracket.
As for smell in the garage - my 911 (1978 SC) also vents to atmosphere and I do not get any heavy petrol smell in the garage, but maybe it does not get hot enough over here for me to notice it?
I have not had a chance to test it yet, but I did start the engine and let it idle for some time and I did not get a CEL from having removed it all.
My car was not the same as the diagram that Brad posted. I Think the US cars have more stuff in the system than the cars over here. I for instance did not have item 5.
