The extender kits usually use a standard outboard motor fuel tank. If you are concerned that the fuel line is too close to the running generator, simply disconnect and move away to fill it. If you do it quickly there will not be enough vacuum to shut it down. An alternative is to have two tanks and swap them out, they have quick disconnects.
I've never had a remote tank, but it seems to me you don't even need to move quickly to refill one. Unhook the hose from the remote tank and carry it away from the running generator. You have at a minimum a few hours to refill the remote tank before the internal tank runs out. Once you fill the remote tank carry it back over and connect the hose again. The onboard pump will pull a vacuum and refill the onboard tank. Obviously the faster you refill and connect the tank the better,. But I'll bet it takes a good 10 minutes to even burn up the small bit of fuel that is sitting in the generator filler neck.
