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.

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?

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