Where can obtain that fuel line, I think mine has a vacuum line on it. Also, where would the Fuel Pressure Regulator be located? I have another question posted about the WUR, where do the vac lines coming from the WUR connect to? I think I have this question in the vintage section as well. I really appreciate you responding to my question, I have been trying to get help on these issues for sometime now, thanks again! It's difficult trying to fine people who understand these older Mercedes.
