While replacing the oil filter housing, I snapped the plastic vacuum pipe that runs from the underside of the intake manifold. I had thought about replacing the pipe with a rubber vacuum hose, but our friends in Stuttgart must have chosen plastic over rubber for a reason. Perhaps a rubber hose may collapse under vacuum? I have been unable to determine the part number for the pipe. There is a number on the pipe, 17 21 17 07 12, but this must be a manufacturer part number. Anybody have an idea of the Mercedes part number? It's a 2013 C250.
What was it connected to? I dont have a C250 so no idea. If I search "2013 Mercedes W204 C250 vacuum Hose" it comes up with alot of photos. I just dont know what it originally looked like, what the other end connection looks like. if I can match it with a photo can get the part#.
The plastic pipe is not sold separately but as part of an assembly. The EPC image is not very representative. For the similarly heavy-handed shade tree mechanics out there, the part number is 271 018 09 29 and is called a Bleeder Valve. Many thanks to TimC300.

So, the valve part is the big round thing at the end where all the pipes converge. I doubt your broken piece has any internal valving, such as a check valve. If not, depending on the price of that assembly, I would get a fuel/oil resistant hose and use that. Many times the shaped pipes are that way for convenience of assembly and overall tidiness of the engine bay.
Found the part at autohausAZ and for $142 I would try the rubber hose first. As long as you don't have any sharp angles where it would kink, it should work fine.

Or, find a short piece of rubber hose to "splice" the broken pieces back together. Just use hose clamps to secure everything. Is the plastic brittle and needs to be replaced anyway? Or were you just being brutal?

The plastic pipe is very brittle. It's probably the result of age and repeated heat cycles. The ends of the pipe also have internal metal reinforcement rings to prevent collapse. For me, at least, the effort involved to reach this point justifies purchasing the assembly, and I don't know if any of the other hoses might be suspect. It's easy to swap out with the intake manifold removed.
if you look closely at the 1st photo of the original hose it does have the part# on it, can see the 018 0929 up near the end.
Part# 2710180729 does look like its the same, minus the 3-way connection and additional hoses added on. If one wanted to go the least expensive route I wonder if you can use that part, cut it accordingly, and try to flare the cut end and insert a barb type splice connector. May need heat to get the hose pliable.
