Windshield washer hose and T connector issue
 

Hoping I could get some help. I cannot use my windshield washer fluid since the little plastic T connect (see attached) cracked where it connects to the nozzle on the passenger side. No one seems to have this plastic T connector and it's a strange way to connect this hose/plastic piece which makes it very difficult to retrofit or jerry rig something. Mercedes have the piece but you need to buy the entire hose accessory line $200 plus dollars and another $300 to replace. I all I need is this plastic piece...everything else works fine. Any help would be appreciated.

The MB part number is 1718600492

is there something special about that connector? Try a search "vacuum t connectors"

Hose connector
 

Looks a lot like the air fittings used for fish aquariums. Maybe you could adapt one for your washer hose.
