So the vacuum on the generator fuel tank would power this pump?
Vacuum from the engine. You drill a small hole into the air filter box and cram a rubber hose in it. That gives you a little puff of vacuum every revolution. This spins the impeller in the pump and moves a little fuel.
For generators with a separate fuel shut-off (like Yamaha), you can leave the fuel tank empty and shut off, and attach the external tank after the shut-off with one of those marine style quick connects.
I think Champion have a shut-off too?
There's video on YouTube that explains it better than I can.
