Thank you for the reply, I have tried both and no diagram I have found matches what I am seeing under the hood.
I think you are talking about the condenser to receiver/dryer hose.

That hose is MB p/n#1248304915. List price is about $55

You will also need 2 of the following seals. MB p/n#1409970645

That's not it, that is the only part I have found, I will try and take some pictures and upload them here it has the high pressure port connected to it...
I had some trouble finding one of my AC lines. I took the line to a hydraulic shop and had them re-use the fittings at the end and use high pressure rubber hose to replace the bad section of pipe. But if the fittings or valve is destroyed, that likely won't work.

the fittings look fine to me, what kind of hydrolic shop did you go to?
Any hydraulic hose shop can do it. Your profile isn't complete, but assuming you're in the US, get in the yellow pages or use Google to find a shop near you.

Any of the E240or E280 or c240 or c280 will fit on that body the compressor sits at the bottom of the motor on all ov the v motors.....good luck

On the M104, IL6, the compressor is on the lower left front the of the motor.

You should also replace the receiver/dryer.
I've got some good news and some bad news. I finally found the part number "1042301056" number 10 on this diagram https://www.google.com/search?q=1042301056&oq=1042301056&aqs=chrome..69i57j69i60.1015j0j1&sourceid=chrome&ie=UTF-8#q=1042301056&safe=off&tbm=shop&spd=18063666510679214713
You will find the bad news there...


I highlighted where mine broke, the hose burst out of the fitting here https://i.gyazo.com/0f5bcb845ed140fe78c84f5cfb1caa19.png
Uh oh... why does it look like there are fuel lines connected to it as well? https://i.gyazo.com/6b54baf2487ae5a31f135e8fa3cf62a3.png
The place you highlighted in post #12 is the A/C manifold hose and is connected to the compressor.
One more thing, when the manifold hose breaks/shears it is almost always due to stress and/or vibration i.e. bad engine and transmission mounts.

after taking a closer look at my car that diagram I posted is not quite right, here is a picture of the actual part it is all one piece... https://i.gyazo.com/a9ee0abb25c0dd1e2868c64b91dec2d7.png
Red is where the hose came off from the fitting
Blue is where it connects to the top of the compressor
Green is what I pictured in post # 13 where it looks like it is connected to the fuel lines

If it would help I could try and make a video but its really hard to see anything in there without taking the whole intake manifold off.

I think it might have been due to my FUBAR both motor and tranny mounts have been replaced about 5 months ago, I think I might have over charged the A/C system... when I emptied the can the gauge was still in the red accounting for ambient temperature I'm thinking either it was an already week hose due to the motor mounts being previously bad or a bad pressure gauge that led me to put too much refrigerant into the system.
OK, so we're still talking the A/C manifold hose. What you circled in green (in your last post) is just the fuel cooler.
Red is the high pressure line going from the muffler to the drier. Green is the low pressure line going to the fuel line cooler.

But it is still all one piece correct? I wasn't aware that there was a fuel cooler on my car that's kind of strange that it is attached to the ac system...
Yes the HP line with the muffler is one piece. It's hard to find. You could check Amazon by entering your car's info. You could do with a line without a muffler as a last resort.
