Connecting vacuum lines to connectors?

Question by dbkluski posted 2 months 3 weeks ago in 2000-2006 (W220)

Hello,

 

I have a 2002 Mercedes-Benz S500 and I had to replace a door lock actuator and while I removed it I broke some vacuum line connectors.  Now, I have the new connectors I have the yellow central locking vacuum lines, but how the heck do you get the vacuum line onto the connector because it is very, very, very tight almost like it was done by machine.

 

Thank you.
