There shouldn't be one but there MIGHT be one! My 1973 302 auto had one. Apparently Ford used the return line configuration when they expected vapor lock to be a problem. If you have a return line, it will be "Y'ed" off of the line which feeds the carb. Just follow the line up from the fuel pump and see if there is a Y anywhere between the fuel pump and the carb. If so, you have the return line.
When Ford used a fuel return the system was called "Hot Fuel Return". Diagrams can be found in some manuals. They were most common on 460 applications.
