@Bozman52 Many thanks for the "shopping list". Thanks for confirming the parts are MB dealership prices and that the diagrams are from the SLK drawings held by the dealership parts dept. We can then compare them to our Crossfire drawings and covert across as required. I.e. the fuel filter is item 20 on your drawing, but item 17 on the Crossfire drawings?

Many thanks to everybody else as well.

Now that I am back from my holidays It looks like it going to be a full change of everything associated to the fuel dampener and associated hoses.
