Hey Kaleb, I found the box from Napa that my AC fitting adapter for the vacuum pump to hook to the yellow hose, came in. The part number is 409551 non napa part # on their website http://www.napaonline.com/MasterPages/NOLMaster.aspx?PageId=430&OEMPartNum=409551
Looks Like I got off cheap, they get $9.40 for it now -------Robert _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
