So I bought a used 92mm combo for my new motor that came with FAST fuel rails but not the connecting lines. I'm trying to find out what is essential to connect the fuel rails and make them function efficiently. There are two stock fuel lines one for flow and another for return. I've seen some fuel rail kits with a crossover/transfer line in the front and another in the back of the fuel rails and fuel lines hookup to the driver's side fuel rail. I've seen others with just a transfer/crossover line in the rear fittings.
What is the best way to hook this up? I'm doing a N/A setup for my 408 and need some advice. Any pics you guys have would be great of where the actual stock fuel lines hook up to the stainless braided lines.
below are the two stock fuel lines
a friend of mine found a pic of one way to do it below
