Check this out guys...I have a a post some where on here that talks about changing hoses. Once you start changing hoses.. Change dry or wet hoses. I start from my engine bay to my 1981 300td gas tank. Also I have a reserve tank that's inside of the car(hoses included). But I truly believe you have to watch out for the hard lines that run under the car. These lines are covered with that "black tar". Your lines could be rusted through and you just don't know it. Don't be afraid to get some extra rubber from the parts store. You never, never know when you will need it. I always keep different widths in my safety kit. Finally, I hope you can watch this video I made. It will help everyone out a lot! Can you say save me some money!! Also you WILL HAVE TO DO THIS. Why? MB doesn't make some hard lines any more.
