Ok there are two ends of the fuel rails one with a valve at the end, I believe the fuel filter goes to the valve on the rail and the open rail is the return just swapped motors and the tape marking them fell off

 

Very confused here... what exactly are you trying to ask. Which side of the fuel rail goes to what side of the engine or which line from underneath the car goes to the fuel filter and then the fuel rail? How could you possibly confuse the lines??

 

I got it figured out, i threw my gas lines on backwards. Haha i had everything masking taped and labeled but the fuel softened the glue and they fell off I had them disconnected at the top,it is very easy to confuse them where they go rubber to two metal lines same size same clips
