<DIV><FONT size=2>If you are talking about the float valve there should be a
sprung metal pin at the bottom that the float lever bears on. The tip was
originally brass and conical going into a circular chamfered seat, later changed
to Viton which is typically black or red, but still conical, see here <A

My manuals don't show what you describe, but Moss Europe for the HIF does seem
to show the moving part of the valve upside down relative to the float, but the
HS is the right way up. It's not possible to tell from the US Moss
site which way up they are in either HS or HIF. </FONT><FONT size=2>That's
not to say that someone hasn't installed a really rubbish copy.</FONT></DIV>

<P class=MsoNormal>As to the valve: the manual and I think Moss show the
rubber down which hits the lever, leaving the brass to close against the valve
hole at the top.</P></DIV></BLOCKQUOTE></BODY></HTML>
