Default LS1 fuel system question?

Im getting ready to do an LS1 swap into my 69 camaro. I was looking at the thread that shows the basics and i have looked at a few that other people have done. Most people just run 1 pressure line to the motor. What do you do on the other side of the fuel rail where the reture normally hooks on these cars? If you are regulating the pressure back in the system do you not need the return on the fuel rail? some help would be nice as im starting this project in the next week. thanks

Depends on the year of the motor/fuel rail. The 97-98 Fuel rails need a return line. The 99 and up do not. There are different schools of thought on which is better. The single line is definitely simpler. With the single line people use a pressure regulator that has a return line to the tank. If you mount it close to the tank, it saves on plumbing.
