Just picked up this 74 FJ40 and the previous owner de-smogged it and added a weber carb. It appears the previous owner was in the process of replacing the old fuel tank when he passed away. I hooked up the fuel tank and now I’m a bit confused when I see the carb and no obvious port to connect the fuel line return from the gas tank. Also which port on the carb does the line from the charcoal canister go to?
