I'm not really sure what the sleeves are...I went to my parts dept with the VIN and these are the parts the M-B system spit out as being necessary for this repair. I asked the parts guy what they're for and he just shrugged. I never thought about all the gas in the tank dumping on me, guess I would have learned that little lesson the hard way if you guys hadn't pointed it out.
