Vapor Seperator Questions

I have a 73 Roadrunner, currently in restoration, and there is one thing i have not been able to find a replacement for, the Vapor Seprator that mounts in front of the fuel tank.

First, does anyone know if replacements are made by anyone? I have checked everywhere with no luck. A salvage yard part is most likely in just as bad of a condition.

Second, this is the 4 line type, and the inside is pretty rusted, so does anyone have suggestions on how to restore it, get the rust out of it with out destroying it or messing up the check valve?

Let me know if anyone has suggestions on restoring or where to locate a replacement.

Thanks!
