Im cleaning up my engine bay and I'm trying to get rid of what i can. The two little lines go into the firewall and the large line goes across the engine bay into a nipple on the vacuum tree marked "A/C" . Can I get rid of this line?
I'm just talking about the large one that goes to the vacuum tree. Can I just remove that line from the vacuum tree and splice it into a different vacuum line so I don't have that big line running to the other side of the engine bay?
Which one of the two lines is for the heat and which is for the A/C?
My A/C is currently stuck in the defrost position and one of the lines is missing (read been broken off). I figure it is for the a/c. Does anyone have a diagram so I can chase down how it is routed?
