Got a 2000 1.6 Focus, had a jerry can with about 3 litres of what I thought was petrol in the garage, decided to chuck it in.

There was a 1/4 of a tank of petrol in at the time. I've gone about 50 yards and the car has conked out, went to move off, had no power, it's coughed and spluttered and died and won't restart.

Is diesel denser than petrol and went straight to the bottom of the tank? If that's the case, will I be able to remove the fuel hose at the engine, crank it over a bit, chuck all the diesel out and restart it with whats left of the petrol?
