Part number please

[Jim Peace]

I am not near my books. Does anyone know the part number for the fuel drain under the fuel selector?

That appears to be a field modification. There is normally a quick drain with a ring you can pull in the cockpit. You still have the support bracket for it at the top. 

I think you can find what you need here:

Yeah I have no ring. This is how I bought the plane nearly 10 years ago.   Just a leaking valve.  Tried to cycle it about 20 times. 

Being modified there is no part number in the book....

So I guess I have to remove whats on there and scrape paint off and look for a part number...

Good news is that when the selector is in the OFF position the leak stops and nothing to drain....so should be an easy fix...

I think this may match what you have.    You'll need a measurement.   Also, it looks like there's a servicable o-ring on it that might fix it.   Turn the fuel selector off, drain it, remove it, check the o-ring.

That’s a rather unique installation.  The valve is a CCA 1550

Thanks M20doc

That looks like a DMax rebuild (or other MSC maybe). Mine was overhauled last year and Maxwell’s did it the same way… Cessna style fitting I believed he said…
