i am going from tbi to a carb the fuel line is on the driver side the carb inlet is on the passinger side does any one know if i can run a rubber fuel line or a steel line from the pressure regulator to the carb what is the best to use. thanks

 

Use some high quality braided stainless line (Aeroquip is my preference) and route the line along the engine cradle and up to the carburetor.

 

So I take it you have an Edelbrick carb?
A good (and safe) rule of thumb is to run as little rubber hose as possible. You want to run a steel line from the regulator, and you can run it along the firewall to where you will make a bend towards the engine. Then a rubber or braided hose from there to the carb, if it's not a real long run. If you're wanting to go braided all the way, then it won't hurt to run that in place of steel line.
