Whats a good thing to use to replace that line. I can just replace the whole section b/c Im not sure where its cracked or leaking from but its deff a vac problem b/c all I get is the defrost vents to work.
That particular line isn't for sale at any auto parts store, but you should be fine with the smallest line you can find. There's a fitting near where it enters the firewall where you can just disconnect the broken line.
I'll do some looking around if I any of the stores around here dont carry the hard line I'll just get the smallest line I can find. Even though I know I have vac issue I want to get it fixed before the car is re tuned again. I know its not the cause of my gas mileage b/c that line has been broken since Ive always had the car I think or soon after I got it.
