Leaking fuel tank shut off

[Mark Shayne]

Hello fellow Skinny birders. My fuel tank shut off valve is leaking past the packing nut. Does anyone know what the correct packing would be to use so I can rebuild it? Maybe it’s a generic packing that’s fuel proof. But thought I’d put it out there and see if anybody else has done this before.

Thanks,
Mark

Are you able to take a photo of the valve and post it here, Mark? Over her 80+ years, she may have had the factory installed valve replaced by a non-standard type. Is there a second valve installed down under for draining the fuel tank sump?

Hi Andy, I’ll go down to the hanger tomorrow and get a photo. Pretty sure it’s original. And yes, there is a different valve for the low point sump.

I have some old drawings. Drawing number 1817 refers to “fuel shut off contro, drawing 1846” I don’t seem to have that drawing. It may show the spec on the packing. I will get a picture of what is presently installed for the fuel shut off valve and send it tomorrow.

I wasn't able to make it to the hanger today to get a photo of my leaking fuel shut off valve, but should be able to this week.

Appologies for the orientation of the images, it somehow changed when they were added.
