The fluid I am using is correct as per having the same specs for the"proper" clear or whatever color the ridiculously priced MB/Febi stuff is....no worries. It is used in aircraft landing gear and probably gets dyed red for some sort of aviation reason. Don't know. Don't worry about what fluid I use....It gets cold up here and I have used it before for years with no problems with any of my components. I used new rams as well as rebuilt the valve with a kit, on this because the old were worn out and leaking....not because of the fluid I used, but because they were old and the previous owner did not take care of them. It was working great until this leak came up...used it for the past 6 months no problem until now. It gets cold up here in the winter and this is the fluid I choose. I think others are using it as well. I agree that it is a downfall using the red dyed fluid because it looks the same as ATF fluid, but it is the way it is.

I have traced all transmision lines and it is NOT coming from them. It is definately the line under the engine that is leaking. I am familiar with the high pressure line fix as I have done it before, using this sites help. It is not the high pressure hose leaking. I can see down to the little junction box where the two lines part in different directions, when it turns to steel line.

Is there anyone that has bypassed the section under the engine, on the 85' w123 or w124 wagons.... if they (w124) have these under the engine set-ups as well?

I think it was just the 85's that got the drivers side tank?

The section of the steel line under the engine is unaccesable as we would have to lift the engine to get it out.
I would like to cut the steel line on either side of the engine and re-route a new section back over to the tank to seal the circuit up again, as it is dribbling from the leak point under the engine. I want to avoid running my new rams dry as well.... as they are expensive.

Anyone see a problem with my idea to bypass this to fix the leak?
Recommendation on a size of line or type of line to use. I am most likely going to use something flexible like hose...and just hose clamp it on there since it is just a return line.
Thanks, for the responses... I appreciate the effort to help, anyways.
