Title: New Injection Lines
Post by: Jack Jones on February 11, 2014, 03:47:09: Can anyone confirm if the replacement injector lines from Mercedes are Cadmium plated as the original lines were?

Post by: wwheeler on February 11, 2014, 03:58:47: I haven't seen a replacement line, but I doubt seriously it would be yellow CAD. It would be more like yellow zinc which looks similar to yellow CAD but isn't as durable. I haven't seen one replacement part lately from Mercedes that was yellow CAD. I think CAD was being phased out by the time our cars were made.

Easy way to clean the inside is to take a old bike brake cable - fray the end - pass it thru the line and the attach a drill to the end that is not frayed and pull it back and forth thru the line to clean any crud that in there. Attach a rinse system to one end flush out with brake fluid.

I concur with Wallace; extremely unlikely that (unless NOS) a new line would be cadmium plated. That does not prevent you from getting your new lines plated in cadmium; I have done that with new parts that were incorrectly finished. What comes to mind immediately is the automatic transmission filler tube. New ones from MB are now painted black. I bought a new one (a mechanic failed to double wrench it at the transmission end, twisting it to the point of cracking but no leaking; I saw that as trouble waiting to happen) and immediately sent it out for true cadmium plating with a gold phosphate wash. The cadmium does indeed hold up better in the engine bay than zinc.
