If you go new, the pump will be pricey. I'd be careful about buying used, or something out of a junk yard. There have been a number of discussion threads on this forum regarding using a generic pump, or something off a Ford or Chevy (sorry purists...), but I don't recollect whether that was ever put to bed or not.
The fuel pump is pretty cheap. I paid something like $19 at Kragen. Try also Napa Autoparts, or if you want to shop around, do a general google search for Mercedes W108 parts. You'll find a number of companies that support parts for our old beasts.
Additionally, there's a part of this forum labeled "Online Resources." You might find something useful there regarding your fuel system.
