just stick a hose in the keep it as low as you can, even crouch down at the side of the car and start sucking, 1ce it gets to your mouth pull the hose out and keep it pointing down and keep it as low as u can and make sure u have the other end rite at the bottom. your injectors should be fine. its worse the other way around as petrol burns the tips off diesel injectors. the diesel will prob just lube things up a bit lol, as for whats in the lines i wouldnt worry about it, it will burn away eventually and be a bit smokey
