[W126 Coupe] EHA replacement

[Richard Hesek]

  Hello,
 Last week I was faced with the replacement of my EHA unit in my 87 560
SEC.

 The initial symptom was leaking fuel but after replacing the device I
realized I had been living with a poor performance.
Nice smooth run now.

  Before replacing the EHA, however, I searched the archives for any
additional info that might help.
One post, from last year, indicated an adjustment within the EHA to
increase fuel pressure for older (100k miles +) engines.

  Does anybody here have experiance with this adjustment?

Thanks,

 Rick Hesek
