Thanks, well-made and funny video about an iconic car with, as you said, weird fuel lines going to the air condition compressor. We in Germany call that system K-Jetronic, I worked on back in the days. Good luck.
Dual fuel pumps in pass rear? Check them really carefully. Usual stuff. Take lines off at motor see if fuel flow. Those pumps go out regularly, usually bottom pump fails( change them both). Pump change check polarity on pumps. I purchased some cheap ones from carparts but the polarity was backwards( with pumps on if hear bubbling through filler neck its backward). Onward!!!!
Such a shame a car this beautiful fell into such neglect. What to do?...bring it back to showroom if you have the time and money. Old cars are only cool when they're perfect. Otherwise, they're just beat up old cars. If you're not interested in doing that, sell it to a junk yard for parts so other Mercedes can be brought back.
