You will need to retain the "demand regulator" (
the big one) for this approach. The hose from the demand regulator to the generator is also a "specified" length and that little black barb at the gen fitting needs to be retained. (
believe it cuts off gasoline flow?)
You can loose the initial high pressure regulator (
the small one) when utilizing a low pressure (
regulated) port.
But, get both!. For my Champion 2500 dual fuel I separated the demand regulator from the initial high pressure regulator and added a QC approach as shown below. I can use the trailer low pressure QC, or #20/#30/#40/etc.. tanks directly as needed. You can also use a "standard" QC propane hose extension if wanted to move the gen and demand regulator away from the trailer QC port.
See here for some ideas: (
different model Champion - but same idea)
