SL/R230: 2003 SL500 Rear ABC Hose Part Number
Not finding a part number stamped on the hose?


MikeJ65, what other lines can I expect to replace soon? Maybe I should replace some or all preemptively? As things are now, I wouldn't take this car on a long trip for fear of being stranded with a broken hose.
1) Disconnect quick connect at valve block tube.
2) unscrew rubber isolator with 3 hard lines Running through it.
3) Disconnect hardline from T-Connector.


After the rear pressure line, it gets a bit more complicated as to which lines to replace proactively. The front pressure line is also failure prone, but it is way more difficult to install.. This line is the one with the tee piece attached. You might look at the posts where people replace the hose portion and reattach to the tube with a compression fitting. While the compression fitting is not as good as a new solid tube, it does allow you to get back on the road quickly. You also have pressure lines from the pump to the pressure valve and the valve to the tee. The strut lines can fail, but in my opinion, they are not high enough risk to do preemptively.
