80' 300SD Heater Valve

Hello All,
The heater valve in my 1980 300SD was bypassed before i bought it. I was reading the posts here on why my heater was always blowing hot air and discovered the bypass. I am planning on going to pick n pull to get a used valve, but have a few questions about replacing the unit.
1. The vacume lines (im assuming they are vacume lines) at the top of the unit look hard to put on/off. One of them on my car is off and i couldnt put it back on. Does anyone have any suggestions on what im doing wrong.
2. I understand i need to check the bellows on the new valve, is there anything else i should look at?
3. Any other suggestions, comments, ideas would be greatly appreciated.
Thanks,
Matt
