AC return hose
Has anyone replaced the larger diameter AC return hose that comes out from under the battery tray? Mine sprung a leak and I can't find it in any catalogs.
Does it go through the firewall all the way to the evaporator? Any info would be helpful. Thanks! |

It is number 56 in this diagram. I can find it for up to '81 models, which is P/N 1238305715.
I guess I'll have to pull it out and have one made? |

I had to have my liquid lines rebuilt on my 300SD. You might be able to find a local shop that can crimp new hose on the ends. I'm assuming it is the hose leaking; not a bad O-ring at one of the connections.

Yeah, the leak is right in the middle of the hose.
So I take the battery and tray out to get it through the firewall? |

There is a hose you can buy, keep looking at that 56 part item, and you'll find it on various trims of the W123. There are about 4 different part numbers that apply to that item. For some reason, the EPC doesn't indicate well, what part number is superseded by another, if it is compatible or not. I had a very helpful parts person, work it out, and we ordered that same hose for $45. It is being shipped, and I should have it next Monday, I'll add here again if it fits.
