Passenger Compartment Fuel Smell-1973 Edition

[Newell33]

Yes, this issue has been hashed and rehashed for quite some time, but I'd like some clarification on how to proceed. I recently picked up a 1973 Spider. It currently has an Interco/Weber 34/34 carburetor installed on the 1600 engine. I've been working to get the car sorted, and have added a Holley fuel pressure regulator to the fuel system. At some point an electric fuel pump had also been added. During the install of the regulator I noticed that there are two metal fuel-related lines on the driver's side of the engine compartment. These lines were both plugged with a short piece of rubber hose and a bolt in the end. I am guessing that one of these lines is the fuel return line, and the other must be the line that ran to the fuel bowl vent on the original carb (none on my Interco/Weber). When I looked in the the trunk it appeared that all of the original fuel lines/check valves, canisters, ect. were still in place and mounted in their OE locations.

Knowing the information above, is there anything that I can do to help with the smell? On long drives my clothes end up smelling for the rest of the day. Should I add a charcoal canister to the engine compartment and tie it into the the two plugged lines?

Any help would be appreciated

Thanks!

On my 1980 there are three metal fuel lines in the engine bay: supply (8mm or 5/16"), return (6mm or 1/4"), and vent (8mm).

I had a fuel smell problem in the trunk that was significantly reduced simply by replacing the old fuel hoses with new fuel injection hoses. Perhaps replacing old fuel hoses would help. Having a charcoal canister hooked up to the vent line wouldn't hurt.

My clothes also smell after driving. Part of it is an exhaust leak. I also discovered that my crank case breather hose had cracks in it. This may contribute to the smell.
