1984 300D Turbo Injector heat shields

I just bought a 1984 300D Turbo Diesel with 204,000 miles and it ran great on the 700+ mile drive home getting 25 MPG with lots of power. The injector return lines were leaking a little so I got the Bio hose kit from Mercedessource and installed it last weekend. I pulled all 5 injectors out (keeping them in order) to get the old lines off (they all broke when I pulled on them) and put everything back together per instructions, but minus new heat shields. I now have the following problems that were not present before.

1984 300D, little bell shaped device?

Hi all. I just installed new Bilsteins all the way around and the difference in the ride is noticeable. As I was on my back (driveway project as Mercedessource calls it) putting the driver's side rear shock in, I noticed a little bell-shaped part with a small fuel line or hose connected to it. It is located just in front of the rear wheel attached to under-chassie and in from the rocker panel. I really didn't bother tracing where the hose led to or came from and I don't know if there is one on the other side. My only guess is a vent for the fuel system.

300SD Adjusted valves by the book, now won't rev ???

n/aI am new to Mercedes and just bought a nice running 1982 300SD. I wanted it to run nicer so I adjusted the valves. Now it acts as though the throttle is not connected, but it is. Can't hardly get it above idle, even when I push the throttle rod at the injector pump. Starts easy, sounds good,
no smoke. I rechecked the valve adjustment, it is spot on .004 intake, .014
exhaust. I had layed the linkage over to the side, don't think I bent
anything-but the speed control actuator does feel limp wristed-that is no
tension. I double checked linkage-seems correct-the rod to the injector pump has about 3/4 to 1 inch of travel-is that normal? Don't know how I could have
changed that. Could the supply pump coincidentally failed? All hoses in right
