What is this vacuum line coming from the intake manifold and going inside the driver side past the firewall, i cant check where it is going coz ill have to chuck the entire dash.. any idea where it goes?

 

Assuming this is not a joke but that's your brake booster buddy

 

Thanks man, n no, wasnt a joke, still learning parts of my car.. cheers..

 

Ok in that case you should have a more robust vacuum hose in place of that orange flimsy one.

 

thanks man, replaced it with a proper vacuum hose

 

if i am not mistaken, it should also be directional hose!

 

There is a check valve in that line so your brake booster doesnt see positive pressure so make sure you have it installed and facing the right direction or else you will not have power assisted brakes at all times!

 

yup got the oem one with the check valve and put it the correct side.

 

Good deal just making sure! Keep up the good work bringing her back in shape!
