I have a 69 Coupe 350 car that I am doing a complete restoration on. I'm in the process of putting the subframe on now but I'm not sure if I have to run a vaper return line and charcoal canister for when I install the fuel tank, I haven't noticed them on other cars, this is a non-emission controlled car. I got a new sending unit, stainless fuel line and tank from classic industries. I would appreciate any help. I bought the car as chassis only, rust free so I didn't take the origial fuel system out. This car will not be original or numbers matching. Thanks for any help.
