Ok, found a solution for my return line. total cost 3.99. What I did was visited my local hardware store and found barb fittings.
1. 1 - 1\4in bard fitting for the return line hose(stock rubber hose) to the hardline.
2. 1 - 5\16 barb fitting to the fpr -6an hose.
In my case all they had instock that would work would be a 5\16 male elbow and 1\4 female fitting. Which resulted in 3.99. This is one of many ways you can do it.
Here is my parts list for my fuel system with -6an lines with Golden eagle fuel rail and my Edelbrock EFI FPR with dual -6 an input and single -6an out.
