M105A2 Air Tank

[jimm1009]

I assume that this is where the sump valve would be since it is the low point of the M105A2 air tank. What ever it was it appears to be brass and is obviously sheared off.
Standard 1/4 inch thread drain valve??

Thanks, jimm1009

It is the drain valve location but I dont know the thread size.

seems like you may have to use an easy-out. if you get it out successfully then you should be able to tell the thread size.

I had to replace mine and it was 1/4" NPT.
