2.4 right?...you have to take the fuel rail off(you can leave fuel line hooked up) . just releive pressure in system,unbolt two bolts ( 12mm) holding the rail on(under rail),unbolt 10mm bolt holding lines in place on driver side of head,and pull up on rail,being careful not to loose the o-rings from the injectors. when you get that off,then there is a "star" bolt holding a clip that holds the fuel line into the bottom of the regulator,take that bolt out and the line will pull out,and you can get the reg. off. just remember to put a little oil on the o-rings when reinstalling them.
