W124 Coolant leak

[DSSpeck]

Hi guys, I have a '95 E320 Wagon with a M104.992 motor. It has a massive coolant leak coming from the rear of the water pump. I put a pressure tester to it and it just poured. There's to much stuff to get a good look at it. Can anyone tell me if there are any hoses or fitting on the back of the water pump and if these can be replaced with out removing the pump. Or if it's the pump itself that I'll needs to be replaced.
I'm an Army Veteran and worked on CH-47D Chinook helicopters. I'm capable of fixing this myself, but looking for any guidance.
Thank you.
