After reading numerous articles about diesel purge I have purchased some to use on my 1981 and 1985 300D's. My question is that everything that I have read has been on using diesel purge on 617, 616, and older engines. My question is should I used diesel purge on my 1999 E300 (606 engine) and if so is there anything in the proceedure due to the complexity of the fuel lines?
