My 2007 GL450 had a Check Engine Light for a secondary air system issue. I've tested the pump itself and it seems to be fine, however, several of the vacuum lines and the connectors that hold them are cracking. I found the main left and right hoses online, but cannot find the smaller vacuum lines, the blue check valve and the 'Y' coupling (with the yellow bit on it) for the system. Anyone know what those part numbers are or where I can find them? MBPartsPrime.com has the main hoses, but not those smaller parts I just mentioned.

All those are cheap dealer parts.

Fair enough... where can I get part numbers for these items?

Are you serious Biff, all you have to do is visit any MB dealers parts dept and they will be more than happy to help define your needs.

Yes, of course I am serious.

Closest one is over an hour away (one way), so I'd rather be able to have the part numbers to verify they have them and don't need to order them. I'm sure talking over the phone is less than desirable to try to explain what I need, so yes - part numbers would be nice.

I've got to imagine that there are parts schematics that show them somewhere on the 'net. The ones I've found show some of the parts I need, but not the others, per my initial message.

When I replaced similar hoses on a BMW I snipped the cracked ends off the ones I needed to replace and put it back together. Then I took the snipped ends to a local auto parts place and bought the appropriate sized stuff by the foot.

Good idea; thank you!

the small trinkets are usually visually matched at the parts counter... i am sure they are spec-ed in some bom, but where that bom is i have no idea... every parts guy provides method to the madness/ chaos by knowing where various trinkets are in his small parts cabinet drawers...

and yes- hoses - your local autoparts store is your source. just make sure you match them for temp, oil resistance and max pressure (if applicable)
