Greetings....

My '73 911S has 70K original miles on it and drives like a new car. There is one flaw, however. It has a slight gas smell at times when driving. When I stop I check under the front hood, under the gas cap, under the engine lid -- and can't detect any gas smell at all. It only seems to happen when I'm underway and it vanishes when I stop.

Any ideas?
