looking for specs on fuel line assembly 1998 e300
 

I have a fuel leak in my 98 e300. I've been running b99 when i can and heard that the viton lines and hoses are necessary. I'd like my mechanic to change all necessary parts but he needs me to get them for him as there seems to be no one stop kit to do this. what exactly will i need? What size and lengths hoses and o-rings? will the clear hoses have to be changed with black ones? what about the quick connects, banjo clamp, etc. Jim at frypower doesnt even have the specs. I know some of you have already done this but am surprised that there is not a clear description, sticky or diy describing all this.

all your help is appreciated. Thanks in advance

Most of the hoses are fine it is the little rubber gasket rings that are leaking. They need changed all the time on diesel fuel also. A very weak spot for Mercedes design in my view.
