Vacuum tubing on 68 charger ac/heater box

[john108]

1.   Before trying to cut and place new tubing for the vacuum lines, I put the originals back on.
I don't remember the exact routing to each actuator. 
I had enough pictures to help with the attachments.
A few tubes seem too long relative to others when I try to route them, based on pictures I had.
I can try to route them neatly (lengths will change some) but is there something to avoid doing?

2.   The new tubing I have is all black.  Do you have recommendations how to identify the RED and WHITE striped tubed in a way that would last?

3. Besides the 3 RED and 3 WHITE striped actuator tubes, the 7th tube is all black. 
I believe it goes through the firewall to the inlet manifold. 
It appears to be the same size but much stiffer/harder.
Do I require a special tube for this function?

All help would be greatly appreciated.
