Weatherhead Fuel Valve Education

[David Sbur]

I'm a Cessna 140 driver looking for info on fuel selector valves. Noticed some discussion in your archives about the subject. Our old Imperial Valves (108HD's I think) are sometimes a nusiance and alot of us notice the Weatherhead 6749 3 position valve would be a drop in replacement (with very minor valve stem mods). Do you folks have a Left-Right-Off selector in your earlier models and if so what valve do you have? Any 337's/field approvals for any of the Weatherhead Valve models? (the newer ones in Aircraft Spruce with the Delrin seats, 3 or 4 position models).

Just doing some homework. It amazes me that it is so difficult to get things nice and tidy with the FAA on this issue and we have to pay $400+ for an old brass valve from Cessna that leaks and has to be serviced every 1-2years or so. Can't even get the old style valve packing anymore.

Any thoughts, knowledge, words of wisdom is appreciated. Thanks in advance for any efforts.

Gang,

Thought you might want to check out the forum thread on the 120/140 Association website Technical Forum (http://www.cessna120-140.org). It regards a failed fuel selector which apparently has the Jensen STC. I am still trying to get some information on what type of valve you guys use in the 170's, whether it is the old Imperial 108HD, part numbers from Cessna, etc. Am trying to look into PMA stuff for a Weatherhead or even looking into Allen Aircraft Products valves for our birds. Any help or contacts with knowledgable folks in the 170 bunch would be appreciated and might save me some time, effort, money, etc. Thanks in advance for any efforts.
