1991 300ce EARLY m104 - ICV and GAS LEAK
 

While replacing the ICV on my early m104 (with distributor) the hoses leading to and from the ICV tore apart - they were extremely brittle. I put the ICV back in and temporarily taped the hose ends on as I need the car in use - but i do not know the shape of those hoses and I cannot tell from the part photos online which hoses those would be - does anyone have insight?

Possibly related - there seems to be fresh gas on the fuel distributor and around the throttle body - would a failing ICV be related to this gas leak/blowback?

IAC hoses (Look at diagram) :

005 IDLE SPEED ACTUATOR TO INTAKE MANIFOLD P/N A1040941082

011 IDLE SPEED ACTUATOR TO INTAKE MANIFOLD P/N A1041410483

032 FROM INTAKE MANIFOLD TO IDLING ACTUATOR P/N A1040941182

Fuel Leak:
Possibly EHA valve cracked and leaking / faulty O rings.

Thank you so much - extremely helpful.

Here is assembled picture if this helps:

There are 3 hoses. From the IACV there is the S shaped hose that goes to the mustache shaped hose. There is also the small hose from the top of the S shaped hose.

With the parts missing I thought this was a different engine! Very helpful photo - thank you! Those hoses look difficult to replace with the fuel system still attached. I seem to have fixed the hose pictured (to/from) the ICV. The hose that is not pictured in the photo is the one I have on order - that one completely ripped in half.

It seems like A104094182 is the smaller hose indicated. Would anyone know the part number for the hose where the green arrow is pointing?

A1040941182 part 32 on the diagram I attached.

I ordered A1040941182 and it is definitely not the correct hose - see picture below. I believe I found the correct part: A1040941282.
