Just be sure not to mount the regulator to the firewall as it is not NHRA legal if you plan to race the car....more and more tracks are not letting that slide by anymore.
You can also run the feed line to a Y-block and feed the rear of the rails, then the lines from the front go to the side ports of the regulator, then return out the bootm.
If you run a -10 feed to the Y-block, -8 to the rails and regulator, and a -6 return you'll safely feed over 1000HP.
Here's a pic of a customers car of mine, I feed the rear of the rails, run the lines back to the regulator and return out the back like I mentioned above, this keeps the fuel lines as far from the turbo and heat as possible.
