This is an original fuel line and check valve for a Fairbanks Morse Dishpan Z hit and miss gas engine...it is not for the throttling governor version.  It may also work for the 3hp hit and miss version.  It is in good used condition as can be seen.  There are no cracks, breaks, or repairs of any kind that I can see or know of.  It mounts under a clamp in the mixer body.  This assembly should be ready to go to work for you.  It would also make a great spare on the shelf.  Let the pictures be your guide.  I can be reached by phone or text message at 262 573 193 1 if you'd like to talk about it.  Good Luck.
