Cruiser Posted December 21, 2011 Author Report Share Posted December 21, 2011 Update..... it looks a lot like this one http://www.aircraftspruce.com/catalog/inpages/aerosafeguardian.php we managed to pull all the vacuum line from the rear avionics rack area where the pump was mounted all the way to the tee in the vacuum line at the fire wall. It is included. We also removed the relay that triggers the Stby Vac On annunciator. It is also included with the rest of the system. I will post actual pictures this weekend and can send them to whomever is interested. This is a turnkey, ready to install equipment with everything included.
