HVAC Unit Vacuum Pigtail

[Salvagedcircuit]

I'm in the middle of buying parts for my HVAC box restoration, and I can't seem to find the vacuum pigtail that is commonly found in the rear portion of the HVAC box by the evap and heater ports. It looks like the following circled images.
Is this part available any more?

Is the next best alternative to just shove new vacuum lines through the firewall with a new foam seal?

Thanks!

You could always do it the Arizona way and buy some rubber vac line to go over the hard line and just use some of the plastic tube to connect to the other side.

That pic looks familiar. Those two vacuum lines go straight to the hvac panel. The black one is the master feed that the control deck uses to operate all the vacuum motors on the hvac box. The white one is for the heater core bypass valve.

Haha, yeah i borrowed some photos for this post

Thanks for the input guys! I think what I will do is heatshrink a new vacuum line to the last non-broken part of the vacuum line, use rubber hose with the right ID or just replace the entire vacuum line when I open up the HVAC box.

 

What is strange is that the vacuum lines are missing from some comanche owner's hvac box. I've seen photos without then. Why is that? Do people just remove them if they removed the heater control valve? Do folks reroute them when they refurbish the hvac box?

Thanks!
