Question:

Is there or can these generators when paralled run off one propane tank with some kind of split adapter? I have a 25 gallon propane tank.

What you need is a splitter or dual adapter like part # MBS54FR and this will work for you as long as your tank's connector is threaded on the inside not just the outside. If it's threaded both in and out that's okay too you'll only use the inside threads with this splitter.

The outlets on the splitter have threads on the inside and outside. Meaning they'll connect to the generator's regulator/hose assembly just like your tank would have if you weren't using the splitter.

The picture I attached shows a tank with the threads on the inside and outside of its connector. Keep in mind the inside threads are left handed so you turn it counter-clockwise when installing into your tank. The outlet threads are normal right hand threads though.
