E34 M5 (S38) power-steering hoses: rebuild the NLA feed line and pressure hose

The SLS-car feed line 32412226277 and pressure hose 32412226390 are no longer available new. Owners reuse the original hard lines and end fittings and have new hose fitted: clamps are acceptable on the low-pressure feed line only; the high-pressure hose must be professionally crimped with the internal restrictor kept.
