I replaced my MC in 2024 (but not the accumulator, I swapped it to the new MC). It's leaking badly now from the line that goes from the accumulator. My personal rule is do something myself, and if it fails, take it to a shop. So that's what I did. The shop says the MC and accumulator should never have been separated or the line can leak because of the high pressure. I'm not sure why Toyota was able to sell me the MC without the accumulator, but I guess that's on me and I'm sure some folks are gonna remind me of that anyway, lol.

Does this sound right? Is there anything I can try before replacing it all? I can't afford a new MC/accumulator, they're currently going for $2,200+.
 
I don't have personal experience with this exact system but if there's a hose that a manufacturer can install without leaking, then anyone can install that hose without leaking with the right tools. It seems a waste to replace a brand new mc. Is this a flare fitting? how is the hose secured currently?
