OK here you go. This is not all of it but this is 90% of it. There are one or two more I haven't sussed out yet, like the one on the canister purge valve.

104-094-35-82 Hose between bottom of intake manifold and A/C mounting bracket (this is a crankcase vent hose). Cost $4.95

104-094-36-82 Hose between bottom of intake manifold and top of throttle body. Cost $13.54

007-997-61-82 Vacuum hose, thick-walled, for all the small short pieces of vacuum hose scattered here and there around the motor. Cut to length as needed. This is the good stuff that fits correctly, not the El Cheapo krap they sell at AutoZone. 3.5mm ID x 9.0 mm OD. Cost $3.40 per meter.

117-078-04-81 U-shaped hose connector on top of the black plastic intake manifold. Cost about $3.50.

601-078-02-45 Branch-off fitting (wye fitting) located on metal part (the lower part) of the intake manifold immediately forward of the throttle body. Cost about $3.50.

117-078-01-45 Branch-off fitting (wye fitting) located at the EGR SOV. You have to remove the black plastic decorative cowl cover on the front of the motor, the one with the MB star on it, to get at this one.

Another very important one is the short piece of vac tubing at the EGR valve located near the back of the exhaust manifold. That is the special red high-temperature vacuum tubing. Don't use the black hose for this one or it will die a quick death. Ask me how I know :-) I don't have the PN for that one yet.

Warning, some of these are pretty tough to get to, for example, the hose between the manifold and the throttle body casting. You may have to remove a bunch of parts to get at that one. I think you can access this one if you remove all of the air intake ductwork and the large rubber connector tube that connects the inlet air duct to the throttle body (the one on top of the throttle body). In doing this you may wack that big connector tube so be prepared to buy another one; they are aobut $25. You also may have to cut off the old ones because they have hardened. All this was easy in my case because my motor was all torn apart.

Do you have a factory service manual? If not you need to get one. They are on CD, about $65, and available from 1-800-FOR-MERCEDES. When you get that there is an index you need to download that makes navigation of the manuals MUCH faster.

Hope this helps!
