an -08 -06 fittings to EFI Hoses

Ok I got a fuel cell from jegs its got -08 feed and return and a -06 ventI gotta go from -08 to 3/8" fuel injection rubber for the outer fuel pumpI also need to go to 5/16" for the return line

From the rubber fuel line,
You would need to get hard line flared to the 37 degree angle, with tube nuts and tube sleeves. Then a AN union to the AN size you wish.
But if you want to tie into the factory lines.....
Russell makes AN to EFI adaptors for ford. you could check that our also. return 6AN pressure 8 AN!
