The A/C compressor froze during this latest East coast cold spell on my 1990 300E. This car is not cost effective to keep the A/C running in so I just want to install a salvage A/C compressor to run the serpentine belt around. I plan on placing refrigerant oil in the compressor but you'll see below why I am concerned that I'll blow out this next compressor.

I had trouble taking the old A/C compressor out as the bolt holding the (manifold?) tubing had siezed badly. Sorry to say I had to cut the tubing running into/out-of the A/C compressor to free the beast so now I have no metal lines to hook the compressor to even if I wanted to. Those lines ran immediatlely to two metal cylindrical units - I cannot find a reference to what those items are. It appears one of them may be something to cool the gasoline before it reaches the fuel manifold. I need to know in case I need to shop for these items. I don't want refrigerant oil spewing from the newly installed compressor. Can I get by with no oil in the compressor?

Any help is greatly appreciated - I hate to see this nice daily driver bite the dust over a simple A/C compressor going up. But boy is it expensive to fix A/C systems on a mercedes.
