1985 300TD - How to Repair Damaged Vacuum Hard Line?

I had a short which burnt through a vacuum hard line under the dash. After that the car wouldn't turn off. I cut out the small burnt section and reconnected the lines with a short piece of 1/8" rubber tubing. The fit seemed pretty snug but still the car only turns off after a few seconds. How can I make a good repair to the hard line? Should I be gluing the rubber tubing onto the line? The hard line is behind the steering column and very hard to access, so the simpler the better.

delayed tranny shifting fro 2-3 on 123 1981 300D

I recently purchased 1981 mercedes 300D. I am having trouble with tranny shifting from 2nd-3rd gear. It seems to have a significant delay. The rest of the other gears shift as they should. I would appreciate help with this problem. My other 123 TD 1984 has the same trouble with the same gears except the delay is about half of the 300D.

84 300D acceleration concern

I test drove 1984 300D with 240K miles showing. She cranked and idled for approx 15 minutes. The dealer alerted me of sluggish acceleration. This was an under statement. I got her on the road and she barely made second gear, so I floored it, engine rev'd higher, pedal to the metal produced maxed speed of 45MPH. Easying off the gas seemed to help shift gear. I ran out of road, brought her back and same thing. asked dealer if he had any ideal what was causing the problem? He says... Fuel filter or maybe the turbo is going/gone bad. Question...
