| Don't forget that the cold fuel is pumped from a tank in the ground. The fuel will expand in the car since a diesel has a backflow (?) pipe, that will put excess fuel from the diesel injection unit back in the tank. The fuel in a diesel car will be something about 20 degrees celsius because of this. So when the cold fuel is filled all the way to the top and starts to expand there's a chance you will start leaking diesel fuel. |
