I have a bunch of that tiny straw size hose in the closet...I replaced mine a couple of years ago, needed like 8 inches but had to buy like 3 feet of it...if you are talking about that hose...I'll give it to you if that's the hose you are talking about...to the idle control valve....yep...I gotta a bunch of it in the closet.....but it cost's nothing from a Mercedes dealership...it was like less than $5....
