Given these vehicles are now almost 15 years old and past history of return lines leaking/failing on the W123 and W124s, it probably is prudent to do this as preventative maintenance.

I am not saying you should not replace all the fittings and the hose, but that the parts separately are a lot less expensive, and better. The factory hose assembly
may have plastic fittings, whereas the aftermarket are chrome plated brass (the ones I got). At the time I only had 4 of them, so I only replaced the one I broke plus the hose. If I had all 6 fittings at the time, I would probably have replaced all of them. There are 3 CDI's that I take care of, so it is good that I have these parts in stock.
