Luberhill Just put a "T" fitting inline after the generator fuel pump then put a shut off in the T to a lenght of clear fuel line. When you want to fill the Honda generator put the fuel line into the honda tank push the prime button on the M/H generator and the on board generator will fill the Honda generator fuel tank.
You can also put a shut off valve on the carburetor side of the "T" and when you park the RV for any time just shut this valve off and run the MH generator till it runs dry, no worry of fuel going bad in the carb and gumming it up.
