Before going to the trouble and expense of adding a second tank, just
disconnect the fuel line at the generator and hook up a 2-3 foot piece of fuel hose and drop it in a smaller gas can.

It will run fine pulling from a can on the ground. This was my method for testing for a fuel issue on my 5500 Onan Gas unit.

I guess you could add a tee and valve to the line and not have to disconnect the main line each time. Just introduces extra connections that could leak though.
