So did you run your breather line from your rear diff into the this t-fitting and the run from this T-fitting out to the ARB breath filter in the engine compartment on the passenger side? I just installed my diff breather today but was debating what to do with my E. locker breather. Where did you get this t-fitting and adaptor?
Yes, I tied the elocker breather line into the rear diff breather line up to the ARB filter. I got the tee adaptor off amazon and the fitting from McMaster Carr. Since the elocker line is 1/8", that's why I have the fitting 1/8" barb to 1/4" NPT.
ARB hose is 8mm OD (0.3149in). The tee fitting has push to connect fittings for 5/16" OD (0.3125in). Close enough to work, and I haven't had a problem yet.
