I have a 4.6L SOHC from a 97 Mustang GT that I'm trying to figure out the fuel lines on. I'm using an in-tank pump with return line. There seems to be two devices in the original lines (see circles in pic). There is a fuel rail pressure regulator and I'm guessing either a check valve or return line pressure regulator to hold back pressure on the rail before returning to the tank? Is that right? I'm thinking of 6AN braided hose to make the connections to the supply/return lines but the return device becomes an issue - do I need it? What do I replace it with (since I can't get the #%$@ thing apart)?
