Coolant Leaking W222
Any suggestions judging by where the leak is at? This is the front middle of the car and seem to be leaking heavy. Link below, sorry I couldn't seem to get embed to work.

A bit of bear but very doable to replace

I'm hoping the radiator didn't get damaged but I'm pretty sure this is the reason why when I add coolant it just waterfalls right out of the reservoir.

Are they pretty much the same parts if references different part numbers? I need 2782001351 but shows cross references: 2782001400 A2782000100 A2782001351

It looks one end goes to the coolant tank reservoir and the other end connects to another piece, but can't seem to figure out what part it is.
Thanks!

Turbocharger Coolant Line: A278 200 13 51
Vent Line: 278 203 12 17
Reservoir Hose 222-501-55-91
Recommended the reservoir hose due to some build up of dried coolant seeping out where the hose connects to the reservoir.
Labor to replace all three parts cost me $350. Thanks to everybody who PM and replied!
