Gasoline Smell....where is it coming from?...6 conversion, Update 5/18 Options

[billh1963]

When driving the car (engine is a 2.2L 6 with triple Webers) I frequently smell gas. This is with the targa on or off. The smell comes and goes...it's not consistent; however, it always occurs

If I stop the car and check around the car (with the engine running) I don't smell it. With the engine running I have checked everywhere and don't see or smell anything. No drips or puddles under the car, around the carbs, etc. I have checked connections on the fuel pump and nothing there.

I have thought of two possibilities:
1. Leaking fuel line in the tunnel (which I should smell all the time...right?)
2. Fumes coming into the cockpit from the engine compartment.

Any other thoughts?


Update: 5/3
Drove the car extensively today and, as usual, the gas smell comes and goes. Stopped while the smell was strong and checked around the carbs...dry
Looked under the car...dry
Opened the trunk...no smell.
Even pulled the gear shift to see if there was a gas smell in the tunnel...nothing

The only thing I see is this line is hanging out in space...could the smell be coming from here?
Should I cap it or does it need to connect somewhere?
Remember...this car has triple webers...it's not fuel injected.

On my conversion, I attached one vent line to the nipple on the engine shroud, and the other line leading to a fitting I installed on my rain hat air filter. This helped with the fumes by actually pushing and pulling air through the carbon canister. It was pretty bad before I got around to connecting the lines.

You did the right thing, George, and it was probably pretty easy to figure out and to do. I fail to see why this conversation still seems to be dancing around that solution .................
