Don't know about the OP's 1996, but the W123 high-pressure hose has "field repairable" fittings. Be happy since those are very expensive. You can remove the fittings from the hose with just box wrenches. I replaced the hose in my 1984 300D and posted w/ photos. I bought "2-wire" (steel) bulk hose on ebay (rated ~3000 psi), but you can also get at Tractor Supply or any hydraulic supply. The SLS hoses are similar and I learned from those posts (many thanks to the wagon owners). Note that the shell which grabs the outside of the hose is a left-hand thread, meaning you unscrew it opposite what you do to open the cap on a peanut better jar. In my 1984, the hose was leaking right in the top middle. When I turned the steering wheel slightly to build pressure, I could see a drop form on the outside of the hose. If I recall, the factory hose was not 2-wire (rather nylon wrap). I think most power steering relief valves are set ~1000 psi.
