Need help identifying a part ABC related

What is this, anyone know if it’s available? My due diligence turns up nothing. The PN appears to be 1203376170.







In the EPC, 220.174, it’s under “LINE SCOPE WITH ACTIVE BODY CONTROL”. It’s the piece between banjo bolts 117 and 115. It’s not called out as anything. I’ve looked under suspension and steering and can’t find anything. Disclaimer….I’ve been known to be blind at times!

Mine was discovered with a broken bracket that I believe contributed to a worn o-ring and then a massive leak.

Thanks!

I answered my own question if anyone else comes across this. The part in question with the broken bracket is part of #110, which is a line from the power steering pump, # 220-320-45-72. I haven't found a new one but they're available used elsewhere.

Well it's more of a theory but I don't think it's bolted to the pump square with the bracket missing. The support bracket was broken, the broken piece was nowhere to be found, which tells me someone had monkeyed with it before and figured it was good enough. I noticed it weeping before but hadn't addressed it yet. It finally sprung a leak, the o-ring didn't look so great so I replaced the ones associated with the "canister". It's still leaking so I'm just going to replace the canister part so it can be secured at the bracket. Even if I could manage to get the old one back into the sweet spot where the leak wasn't pissing, I feel like it's going to be a recurring problem if I don't replace the part.

This has been fixed for awhile but I figured I’d update the thread in case it can help someone else.

I sourced the part in question used, but from an SL500. My car was missing the bracket and the brace from the block. I bought the brace new for about $30 and found the bolts locally. I’ve put about 350 miles on the car since with no more leaks.

I‘ve also installed new o-rings while I was at it. These need to be torqued to spec fwiw. After reading another thread and closer investigation of my original part, over tightening can crack the weld where the fitting is welded to the canister.
