I believe what is being described is found on '84 and '85 318's.  From memory 
of having a cousin with a 318 that was always in several stages of disrepair, 
the damper is a "muffler."  Apparently, the "rush" of fuel for the 
four-banger was considered too loud being that it could be heard from the 
passenger compartment on a perfectly "new" car.  Just replace the entire fuel 
line.  They all leak due to corrosion.  The location was horrible.

Word's of wisdom usually don't come cheap.  Typically right after you have 
screwed up something irreversible.
