FAO those that have DIY'd rear airlines

[rpaterson]

Hi All, first post so be gentle(ish) on me. I've tried searching but not had much luck.
I'm looking for some more details on the parts required to DIY the rear suspension airlines on my 2014 E350 estate. I know the DIN details of the lines and that the unions are Voss 203 QuickConnects but I'm looking for the part number of the unions along with how many I'd need (4??) to replace the airlines from the valve block to the (rear only) airbags and where to buy them.
Apologies if there's a fantastic thread somewhere with all the info on it! Thanks...

Did this job 4 years ago on mine, back then I picked up the part numbers of the lines and connectors from the Merc online parts diagrams, then ordered Genuine parts from a Merc dealer somewhere in eastern Europe. The whole lot cost me 50 euros and the job is very easy. Off the top of my head it was 4 connectors, one for each end of each line.

Originally I had patched up the leaking system for pennies with aftermarket parts, which worked OK, but being in Germany I was very aware that these parts with their bright colours were obviously not original, and modifying suspension over here is not acceptable without lots of paperwork and expense. Hence the switch back to original parts.

Cool thanks, I've recently found a supplier for the unions. It's a job that is moving up my need-to-get-done-soon lis
I'm still recovering from my recent shock of spending £600 to fix a DRL
