How is the vacuum valve for the fuel system charcoal canister supposed to mount?  Mine is hanging freely by the vacuum lines.  It slaps against the frame when I close the sliding door so I took a look and don't see clearly how it is supposed to mount.

  Also I noticed a large crack in one of the vacuum lines.  There is a rubber hose that the white vacuum line connects to, it steps up to about 1/2" in diameter where it meets the valve.  Where do I get a replacement for this stepped hose?  Does anyone happen to have the part number?  What fewer issues might I expect to see once this is repaired?

  Thanks,
  Clint
