[W126 Coupe] Self-leveling suspension

I've had both lead and had to replace them on one of my cars. For the pump,
you want to drain as much fluid from the reservoir as you can or the line
will leak out all over. Then its just 4 allen screws that you take out, the
in and out hydraulic lines, and replace. There is a "key" type chuck on the
inside that you want to make sure you don't lose. The high pressure line
off that pump snakes behind and under the alternator and down below. Its a
PITA to replace, but doable. I practiced on my spare engine first to get
the hang of what angle to do it at. I also think I removed the alternator
to make it a little easier so I could route it under the air pump.
