Just finished installing Jubol's swing valve oil drain. My installation required the use of a 90 degree elbow due to clearance issues. The real reason for this post is to tell you that the Tecumseh drain tube requires a 1/4"NPT valve. The OD of the tube(drain pipe) is 0.540". Sounds crazy because that's larger than 1/2 inch but that's the correct valve size.
I went to the local plumbing supplies but no one had the LOCKING model that Robmints pictured. I ordered it from McMaster-Carr as Mints suggested.Phone # is (732)329-3200. The part #is4629K11 on page 350 of their catalog.Got it the next day. The locking model has a hole in the handle that accomodates a bolt with a ny-lock nut to prevent the valve from opening(bolt and nut not included).
Thanks to Fred and Mints ! No more mess!
