thin white plastic vacuum line
talking about the white plastic vacuum line that connects to the UIM right near the FPR.
i snapped the line while bending the engine harness towards the back of the car, thought it went to the HVAC system but my climate control is unaffected as of right now. i plugged off the manifold for now just so i dont misfire.
need to know what purpose this line serves and if they make a vacuum line repair kit for it thanks.

The white/gray one on the LD9 I thought was the HVAC. I don't know what else it would go to.

I also thought it was HVAC. It's vacuum that goes into the harness and to the cabin. It must run the vents or something.

I thought it did something with the HVAC, but I think it has to do with FPR, like supplying vacuum to make it work

i plugged off the port of the manifold and everything is working fine right now, no misfires, no codes, and the climate control works fine, i am going to fix it regardless but i am just wondering for future reference what that line is for, maybe cliff will chime in here.

I believe the black line supplies the FPR. The grey goes into the cabin.

turns out the white plastic line does do something with the HVAC, it has something to do with the vent control, right now it comes out of all the vents, floor, face, defroster, etc. with the line disconnected. think i figured out my mystery.
