I've had this little jigger sitting in the garage for what seems like forever, and finally got around to installing it a couple of weeks ago. For those with full systems, the servo motor that actuates the EXUP valve becomes redundant, but you can't just unplug it & remove it because you'll get a tach error code. Ivan's kit fixes this problem, and is a fully reversible mod.

Last steps:

  1. Refit cable tie(s) and re-connect fan wire.
  2. Turn on ignition & confirm that you have no tach error.
  3. Refit tank etc per Pat's site.

I hope this helps anyone looking to do this mod.
