Here is a link to our EFI line kit that works with the Boyd tank. They switched to an ORB fitting on the tank vs. a NPT, but we can modify this line kit to work for you. There is also a plumbing diagram and some images. If it has 1-port on the fuel rail on the engine, it is a returnless rail. If 2-ports, it is a return rail.
If your top EFI plate is machined, it is the newer ORB version. If it is hand etched on top, it is a ORB. It will also have "ORB" machined in it, if it is the later plate using the ORB fitting.
