Always remember that the FPR (fuel pressure regulator, that little metal canister on one end of the rail) is the fuel RETURN line....the regulator bleeds off excess fuel pressure and dumps it back into the fuel tank. The fuel filter is on the supply side, which feeds directly into the fuel rail/injectors.
