Most likely the whole tank of fuel will make smoke and that is not good for the catalytic converters, O2 sensors and fuel filters. I would have pumped out as much fuel as I could have, then finished it off by opening a fuel line and bypassing the fuel pump relay and ran the pump until it didn’t flow anymore fuel, then added 5 gallons and primed the system until it smelled like good fuel, then replaced the fuel filter and reconnected the fuel lines, drove it down and filled the tank.

Kerosene or Diesel fuel are heavier than gasoline, so the tank pick-up is getting a lot of the junk now. This will probably last a hundred miles, unless you hit a really big bump and mix the fuel really well.

You should be fine, Kerosene has a lower octane rating than gasoline, so you might get some pinging. Did you refuel with higher octane fuel? Drive and burn it out and don't make the mistake again.

It should clear up after you gas up again.
