Idle Control Valve 190E 2.3 Hose Part Number

Hi everybody, I'm having idle issues on my 88 190E 2.3. I took the ICV out and cleaned it. I noticed the hose at the BOTTOM of the ICV is cracked. The hose goes down and under the injection system. Does anybody know the part number of this hose? I didn't want to tear the hose out because I need to drive the car tomorrow. Anybody give me a hand here? Thanks in advance.
