In my 73 Plymouth Chassis manual it mentions that only 440s came with a vapor separator at the fuel pump for vapor lock. So, did those configurations run a third line back to the tank or did the vapor return outlet on the separator go to an input on the charcoal canister? I came across an article at mopar diy that says that if there is a carbon canister, you can just run the vapor separator outlet to that. I've been trying to find a picture of a 73 440 engine compartment or motor with a vapor separator, but not having luck. In my configuration, there are two lines going from the tank. One from the tank vent to the carbon canister and one from fuel sending unit to fuel pump.
Based on the article, my thought was I could add a vapor separator and just tee the vapor outlet of the vapor separator into the carbon canister instead of running a return line and installing a fuel sender with the 3/8 output and 1/4 return.
Any thoughts are appreciated!

I've included a cap of the article, the second sentence below the image mentions running to the gas tank or the carbon (charcoal) canister.
