Viton for Mercedes Engines

As I am going through replacing rubber fuel system components on my 1987 300D I am replacing them with Viton components. Since I am spending the time and effort identifying the components I thought that I might as well offer them for sale to you also. This list will grow as I replace more and more of the Buna (Nitrile) hoses, gaskets, and o-rings with Viton.

Look at your current hoses. Try to estimate what you need based on what you see. You should need 6-8 inches between each cylinder. Sometimes you will need a foot between the two middle cylinders to get around some of the mounting hardware. Add a foot to get to the fuel filter. Buy a little more if you still are not sure.
