hwo do i install the vapor valve? i already took the old one out, but i dont know which side of the valve faces up, down, back and front! The valve has a small hole in the side and a small indentation in the other side. The valve has a little hole in the bottom/top? and a big hole in the bottom/top....so basically i need to know what faces what. What hole faces the cup seal stick thing
