    swap your rails on to the LQ4. 99-03 came with a return fuel system. 04-06 came with a returnless fuel system. That is just how they are designed....

    use whatever is on your truck now. anything on the motor now dont use. this way everything is correct

    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.
