A lot of things I am, but colorblind is -NOT- one. Anyone besides me who fails to see green or oranges arrows as referenced in the post?

My diagrams from the CSM were intended to show what those items in the OP's photo really were.

Thanks Joe and your time is very much appreciated. I stand corrected! I don't mind the gas smell but she does...so what can i do? Can live with them...pass the beer nuts! lol.
We started to disassemble the carb and I decided to buy a replacement. Rebuilds were near $600 online. I got a used Edelbrock "Thunder/Chromed" 700 or 750...don't remember for $250. Thought this was the best way to go.
I kept the original...I don't think it is worth the time and $ to rebuild especially getting a like new $500 carb for $250.

I"ll be curious to hear how your edelbrock does. I thought of that too but unfortunately my car has a 4GC and from what I understand, I would have to put a manifold adapter on to mount the carb, then an air cleaner adapter to put the air cleaner back on, which I don't think I would have hood clearance.
Cheers,
John

Joe..I hope you are well. Per your suggestion, Sept 2018 - 7:07 PM, to retrofit by 68 442 to a fuel evaporation system...do you have any of the schematics with part numbers? I did some investigation and it appears that the 1972 system might be optimum. Any other suggestions to get this project started would greatly be appreciated. I spoke with some other people and they suggested modifying to fuel injection...close to 3K.

I currently have the same issue on my 70 Chevy. It just started in January. After parking, eventually gas fumes would find it's way into the house. The problem turned out be the crimped seal between the fuel pump steel lower and aluminum upper. Just suddenly started seeping there for not apparent reason.
By the way, it's a custom tuned quad (help from ruggles) without evap canister and the usual thru the trunk tank vent. Prior to this, gas smell was never that bad even during the Summer.
Anyway, you might check the pump. Everything is made in China these days...

I had a similar failure with the pump on my car a few years ago. I backed out of the garage and saw a trail of liquid, looked under the car and gasoline was pouring from the crimp area. The top "cap" portion of the pump could be moved around it was so loose. First time I had ever heard of that type of failure, but you had the same. Hmmmm.
