where is the PC pilot valve

[TheTurtle]

My PC system pilot valve is hanging under the panel by the vacuum lines.  I cant imagine that's a factory option...

The SM says you should be able to access the valve via the #3 panel which is the instrument access panel in front of the windshield, but theres no good picture of where exactly.  I suspect it was moved in the 70s when the panel was upgraded?

Yep, that is exactly where mine (65E) is, just hanging there.  A cube of Aluminum about 1.5 inch on a side.  Two years ago I suspected mine after checking for Boot Leaks one by one and finding none.  I called Brittain Industries and they told me how to bypass and check the pilot valve.  Symptoms were of a ruptured diaphragm inside the block.  After photographing and marking the tube setup, I sent my pilot valve in for a rebuild (about $60.00 as I recall).  The system has worked perfectly since.  I think they also have an exchange program.

Yea I talked to them as well.  seem very helpful and the prices are reasonable.  well honestly they seem crazy cheap for anything in aviation.
