I have a USA spec 240Z, and I've replaced the fuel tank to vapour tank hoses. They were all pretty much knackered with one in particular leaking fuel when the tank was filled/overfilled. Unsurprisingly the fuel smell inside the car is now cured, yeah!
Now when I remove the fuel cap I get a hiss (not sure if it's pressure or vac) is this correct,guess it indicates that the fuel system is closed with no leaks. It's standard carbs and mechanical pump. I thought hissing was only a modern fuel injection system thing.
