which fpr?
I have a 89 rs with a carbed 350 in it. It has a mechanical pump on it as of now but i am running into vapor lock issues when the car gets warm. I am thinking about putting the stock efi pump back in and running a reg of some type to set the pressure for my holley carb. What reg do you recommend in this situation? I am thinking about getting a sum-g3131 and running one port to the carb and the second to the return line. Would this work?

No - it will not work.
You have to specifically get a return style regulator.
Most use the Mallory 4309 MAA-4309, but there are a very few other options that I'm unfamiliar with.
