This is a VERY hard to find original 1/2" American Injector water ejector or tank filler. It is complete as pictured with all of the tail pipes and innards. It's in very good shape with minor wear. All of the threads are in good, useable condition. It has a steel pipe plug in the pick up threads which should come out pretty easily.  This ejector has nice original patina and after some minor attention to that plug removal should be ready for use.  It would also make a great spare on the shelf for a future project.  Original ejectors like this are extremely hard to find so if you've been looking for one here is your chance!  The pictures tell the story.  I can be reached at: 262 573 193 1 if you'd like to talk about it.  Good Luck.
