I assume you have linkage but have you decided to use the fuel return line or not?
If so do you have the correct "T" or dead head fuel line connector unit? What psi is an RX 7 pump and or what regulator are you going to use. Weber's are suggested to not be run with a regulator but seems people have hooked them up many different ways.
Are you aware of the current chokes and jets on your new Webers? I assume they are 40s,,....
