Fuel Pump and 3/8" Fuel Line

I am looking at replacing my original fuel line (5/16") on my 69 Dart with a new 3/8" line from front to back. Is there a Carter mechanical fuel pump that allows me to make that conversion? I currently have a Carter mechanical pump that transitions at the fuel filter into a 3/8" line for the carburetor, but I figured I might as well make it 3/8" from front to back.
