The leak is where the t-piece fitting joins the bottom of the emergency valve in front cockpit. (see pic). I tried tightening the nut but found it would leak if I tried tightening it too much. I thought either the t-fitting might be cracked or the housing of the valve cracked. So, I took the t-piece out and found the rubber washer cracked and dry. So, I'm pretty sure that is the source. Housing looks fine, t-fitting not cracked either. Where do I get new washer? For that matter, probably will get two. Also, I trashed some of the screws that hold the top cover plate down to the inside of the plane, so need more of those as well.

I'd like to know myself so I'm willing to send you one to see if it will fit. If it fits, pay me, if not send it back.

Wouldn't the t-piece still need to be attached the valve in the same manner?

The pipe thread leg threads into the bottom of the valve, no rubber parts needed to seal. I'll try to send you a picture, save a thousand words...........

Dennis Savarese" Subject: Re: Yak-List: Emergency Air Leak update Try Jill at M14P. She may have the rubber washer in stock. As for the screws, they are standard 4 mm screws. I'd suggest replacing them with 4 mm button head Philips screws. Can be either SS or zinc plated. Dennis A.

Do you think a properly fitting o-ring will work? Doug, from the picture, I don't think the CJ valve will work for me. The top elbow fitting looks like it points directly down over the bottom fitting. My top elbow fitting is directed backwards away from bottom fitting. Don't think there is enough play in the tubing to attach it.
