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!

Performing a search on the topic is the best way to access all info on the site about the topic. Doing so did not bring up too much about these valves. I haven't heard of any red herrings that these items have. Good luck

Awilps, what part number did you use for the gasket?

[awilps]

The gasket we needed was B3-12-1. Lots of shops couldn't make any sense of the number, but it came up correctly in B & S's inventory. We have a '68 O-2A. We also found that the fuel line which runs all the way forward toward the leading edge of the wing from the the selector valve was very loose on both wings. Difficult to see and get to, but glad we did! So far no more leaks...I've been replacing almost every seal and o-ring since the ship came from a Florida home and is now working hard in New England cold wx. EVERYTHING has been leaking.

I guess the big question is does the 337 have the same fuel selector valve as an O-2?

AWILPS,

Wondering where in NH are you located. I am at ASH.
