How does this fuel setup diagram look??

Basically Im using the stock hardline to a specialty fitting to -8an/line routed under my Vic Jr intake. It then comes to a -8/-6/-6 Yfitting and feeds both of the rails/injectors. It then tees at the back of the rails with a female swivle side that connects to my FPR. Which brings me to a big questions: Is it ok to have my FPR on the return line?
Here is the diagram:
the layout will be functional, and i guess plenty of room to grow when you eventually move away from the factory feed line... more expensive than something that will work just as good, you betcha.
If that's the way yours is designed, [can't tell w/ a drwg], you have the flow backwards.
