to install a fore and afton an older machine you can get a manual valve like the one used for your unload auger swing. i belive it can be hooked in on the pressure side of the auger swing valve. or you can get more high tech and install a two way elect. selonoide valve the same way. let me do some more checking for some other options. i will check on the plumbing of the valve also.
