it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
thats a return style fuel rail. on the newer models like you have, you have a returnless. like they said just use the one you have now. I had to change mine and get that style bc my intake was newer and just had one

It's because the returnless systems have the fuel pressure regulator in the tank as part of the sender.
