One other question about the Carter pump. reading through the instructions online, it looks like the fuel lines are hook up just like a Holley. In from the tank and out to the carb/regulator. Hyperpasta, you said the pump is internally able to return fuel when not needed to eliminate the dead head scenario and so my question is it is able to do this without any additional fuel lines added to the system? I cannot find anything in the installation manual showing a return line so just replacing the pump would give me return line capability and I could leave all the current plumbing alone.

Would this be correct??

Thanks again.
