I have a 65 Tempest 4dr with a 326 and 4brl carb. I got the car at a lot that just wanted rid of it so no owner history at all.
Heres my question, I have a Carter carburetor and an original looking fuel pump. The fuel pump works great now that I've sealed up the pick up lines, the problem is it seems to be overpressurizing the line to the carb and I am concerned that the float seat will be forced open and overfill the floats. Now it appears that there is a return line (1/4") next to the feed line, but the carb does not have a provision for the return. Am I missing something or does this carb not work on my setup?

I have an idea to just install a T fitting with a small orifice to connect to the return so that the carb receives most of the fuel, but anything extra is returned to the tank.
