I think the No. 1 injector "forward" return line goes back to the filter housing, which is not at injection pressure, especially with the car shut off. With the car shut off, not having hoses on the injector return lines is just asking for trouble later, and, I believe, will allow air into what is supposed to be a solid system. Purging air on the post W123 models is even more of a drain on the starter and battery and can take a while. And, yes, a copious amount of fuel will be spilled. Makes for serious Diesel odors while driving. Jim
