i was thinking about getting rubber line...that way i won't have to worry too much about this plastic crap cracking/breaking all the time.

 

What was the reason behind Mopar using that brittle plastic vacuum line? I want to replace all my line with rubber lines.

 

^rubber kinks, hard plastic doesn't.

 

not if you cut it the right length...

 

that's what I'm thinking...

 

The problem when using rubber is that it softens and becomes very pliable and depending on which grade is selected, this problem can worsen. When pulling a vac on a soft material, it has a tendency to collapse on itself thus losing vac beyond that point.

This is why the engineers chose to go with those hard lines as it's application specific. I would not use rubber for long lengths. Short runs where you can see the line 100% is fine but, not to be used when you can't see it and it's routed around hot engine components.

 

makes sense...however, just HOW much vacuum is being pulled through those lines? i would think, the smaller the line, the harder it would be to collapse in on itself. idk haha, i'm just rambling. i'm not too worried about it. i'll get some when i can and whatever they have on hand. its stuck in defrost mode which doesnt bother me cuz thats pretty much all i use anyway. haha.
