Paul Posted April 30, 2006 Report Share Posted April 30, 2006 I fit mine the same as the original. the wrong way, would put the boost pressure in underneath the piston rather than the side, and possibly give the boost an easier task of lifting the piston off its seat when it should be holding boost and closed.
