At least for the 8th gen (I would be surprised if it was different for your car):
To make the stock feed work, you need a Russell -6 AN male to 1/4" SAE Quick-disconnect female, part number 641303, I then used a Russell ProClassic -6 AN Straight Swivel Coupler, part number 640003 to connect it to the -6 AN ORB fitting on my FPR. This setup worked for me due to the placement of my FPR. If you put it somewhere in the bay other than on the side of the head, you may need to skip using the stock hose and make your own hose from the firewall to the FPR. The good news is, the same -6 AN male to 1/4" SAE Quick-disconnect female fitting can be used at the firewall to connect to your custom -6 AN hose if needed.
