Firewall vacuum hoses
 

2010 e60 with the N52k

There are 2 small vacuum hoses on the firewall near where the heater hoses terminate in the firewall. Theses vacuum hoses are slightly different size diameters.

One end of the hoses terminates in the firewall. I can't see where the other end terminates.

The rubber on these hoses looks old and I want to replace them.

Anyone swap out these hoses? Did you have to pull off the intake?
