Fuel Selector Valve

[awilps]

Hi all! I'm new to this forum, and just wanted to share that we located the cork gaskets for our O-2's fuel selector valve at B & S Aviation in Wichita. $75 a piece. They should arrive today! Hopefully a better solution than the $12,000 Cessna wants for a new valve. I'm a bit unnerved by the numerous listings of parts for this valve listed as "non-procurable" and "discontinued". Coupled with several overhaul shops telling me they won't touch these units...is there a serious problem with opening these units up? I'm new to the airframe and want to give our MX team as much info as I can. Cheers!
