NOT my vent lines because it wasn't doing this before swapping the H30/31 carb (which had its own problems) out for the 30 PICT 3 I'm using now- this issue seemed to crop up about the same time.
It's terrible.

Check the trunk area. After removing my 1970's fuel tank for the first time after 46 years, I got leaks in the 48mm i.d. fuel filler hoses, even with the hose clamps tight.
I replaced those hoses with new, gas smell gone. Check the tank vent hoses too.
Your observation of the smell may be totally unrelated to your carb swap.

The only other thing I can think of that I did around the same time, is install a new radio and reinstall the wiring cover in the trunk. That's it--nothing else. When I had the 30/31, I had NO radio, just a big opening in the dash--yet no gas smell at all. I do those two things and BAM it's like someone doused me in the stuff. I can also smell it in the garage after driving the car so maybe there's a leak elsewhere but I already checked the filler hose AND the sender unit plate on the tank and nada.

Do you have the 'EVAP' system in place?
Didn't happen to pinch off the EVAP lines when replacing that wire cover? (if you have EVAP in place)
Maybe the lines which run across the front firewall and/or something in that system? Could possible get some leaking/sweating there? Maybe the tank outlet line worth a look-see? Just coincidental timing with your other projects?

Did you put in any new mounts or brackets when installing the radio? The gas tank is right on the otherside of that wall and its possible to use sharp screws and poke a hole in it when mounting stuff under there.....I dont want to talk about how i know that....

Get underneath and check the flex fuel hose from the pan to the steel engine tube which goes through the front engine tin, you likely rarely check this.

Did you break the vent hose or vent system vapor separator behind the fresh air box when installing the radio?

I suppose it's possible I did something vent-line related when installing the radio, as that line does cross over the trunk up under the dash, although it routes below that opening. I'll double check and see.
My car is a 69, it does not have the EVAP system or that vapor separator.
It's also possible it's an issue with the line from the steel tube coming out of the pan to the steel tube going into the engine bay- that line is a bit too short and so I had to route it up between the heat exchanger flap and the autostick clutch canister. I did check under the car for leaks and none to be found.

| What about the hard line in the tunnel? Maybe open the inspection cover under the back seat & take a whiff |

Check to be sure your gas cap is on correctly. I know you are way past that in your assessment. However, I just got back from the gas station and was smelling gas. Checked engine compartment first, no leaks, under car, no leaks, in trunk, no leaks. Walked around to passenger side and the fender and running board were covered with gas. Idiot move on my part...   |

Yup...I chased my tail for a week looking for the source of a sudden, over-whelming gas smell. The cap wasn't on correctly.

Funny, because these two things happened at same time for me, in my garage, overwhelming gasoline smell, about 20 years ago.
It turned out that the mechanical fuel pump on my '88 Mazda truck had intermittent leak AND the O-ring on my 1971 Super wasn't sealing well.
So new fuel pump for the B2200 and new fuel cap for the Super....

I haven't messed with looking into it. It's not the gas cap, cause my 69 uses the metal cap that basically goes over the filler neck opening and twists into place (more like a radiator cap), not the screw on type. I've been using that cap for years so it was also in use during the no-smell period.
Once the fuel level in the tank gets down to half it smells a lot less. But there is also a residual smell from the car after it's been sitting in the garage, it's more of a sooty, gassy/oily smell. Oh well.
