67 Mustang Fuel Regulator Question

i like this regulator myself;

it has a nice range for a carbed engine, and it makes it easier to run a return line. just run the carb off one side of the regulator, and run the return line off the other side and back to the tank. the toughest part is running the fuel back into the tank. my advice would be to run a "T" fitting in the line to the fuel pump and run the return to the "T" fitting. it solves a couple or problems straight away.
