1979 450SL Fuel Pressure Regulator Vacuum Line

I put manifold vacuum to that hose on the WUR and it started running better immediately..I have to tee off of another one to put vacuum to that ful injection check valve next..I also came across another line that was disconnected..if anyone has any ideas where that one goes..It is one of two hoses connected to a solenoid looking thing under the expansion tank..The one in question has a black stripe. It goes from the solenoid thing on the passenger side all the way across near the drivers side fender near the egr vavle and then is left unplugged on the drivers side..In the picture it is the bottom one of the two lines pictured on the left side of the picture..Thanks for the help and patience with me..I dont know much about these cars..so some questions may seem dumb but how can i learn if i dont ask questions
