[W126 Coupe] HELP! Car Salling!!!!!

[Dick Spellman]

If it's loud David than I'd presume it's been in there over 100k miles 
or more and may be failing to keep up with the fuel pressure once it's 
been running a while.  I'd ask your mechanic to replace it.  You can get 
one from Jonathan or Rusty.  Put a new fuel filter with 4 crush washers 
in there while you are at it.

If you want a formal test you'll have to set up a fuel pressure gauge 
per the manual to see what it's reading.
