Could someone please tell me how to remove a FPR from a 99 Explorer 5.0. If I am looking at what the Haynes manual calls the FPR (located at the back of the manifold) I can't see any way to remove it. The manual says unplug vacuum line and remove screws . . . I don't see any screws. The replacemnt FPR has holes for them as well. Any suggestions????????????
