You can replace the hose yourself. I did. If like my 1984 & 85 300D's, standard -10 and -12 hose works for compressor outlet and suction, resp. I used "reduced barrier" for the -12. Use a hacksaw and/or cut-off wheel to slice and peel off the factory crimps. You can secure the new hose w/ "ferrules" if you have a Master-Cool crimper (like me), or buy Oeticker "stepless ear clamps" on ebay and use a nail puller to tighten. Breeze smooth screw clamps would work, but look less professional. All can be bought on ebay cheap.

I doubt that accumulator has dessicant bags like your "filter-drier" does. The later is on the liquid line, whereas yours is in gas. It probably serves a muffler/surge tank function. I would slosh ethanol around in it and thoroughly dry it, then slosh some AC oil. If you use PAG oil, don't leave it exposed to the air for long since it absorbs moisture.
