Just look for rubber tubing. I really bet they have it on here but maybe not. If someone could find them on here and send a link that would be cool.

Usually you will get it as like 5feet long rubber tube and cut it up your self into desired lengths. It doesn't have to be specifically for Mercedes, just google it.

But yes the "Y"and "+" fittings u will need to find special, again google it, and then once.you find what you are looking for you will now have the correct name of it so you can do a more thorough search. Lol half the time finding the proper name is the biggest problem in finding parts.

The last thing I will say is that Mercedes Source had a vacuum connection kit with everything you need buy it is waaaay over priced.

I just.goto pick and pull and find good ones from.other German.cars. if you use used ones just cut off a half or quarter inch frpm.each end and they should be snug enough to get you by. The ends just get bigger from having the tube in there for so long.

And thank you for asking your question
