Not sure if I'm posting this in the correct forum, or if maybe this is a second gen 126 thing and the 300SDLs have it... it being a mystery to us, thus i've come here. My friend Turbobenz pulled this out of a 420SEL. He found it wrapped in insulation in line with the compressor low side. He said it was full of fuel in the jacket. What is this doing to the fuel? or is the question what is this doing to the freon? Anyone know? has anyone seen this? It looks awesome polished!
