Vacuum Line Hard or Rubber?

[Kyle89K5]

My hard lines are failing at a REALLY scarey rate on my 89. I need to get the vacuum hoses replaced about 3 days ago. Should I go back to the hard line? All the boots are trashed. Would it really hurt much to go with rubber lines throughout?

Thoughts? Reasons? You're a dumbass quotes? Anything?

I thought hard lines would be better, but to be honest, I think rubber is the way to go.

The "nylon" ones seem to get brittle and don't bend very well...vibration probably doesn't help matters.

My hard lines are dry and cracking and the boots are splitting. I'm figuring that rubber would do the same, and be a LOT easier to replace over and over and over and....

I'm thinking I'll pick up a bunch of hose and get to work in the next night or two. I know that is part of my vacuum leak problems. The MAP sensor is my other big PITA right now...

TTT

Anyone? Is there such a thing as *extreme duty* vacuum lines? Hi-perf. vac lines?

Help a brother out here?

Hey Kyle, I retubed ALL my vacuum lines late last year with hose. Heat, time, and UV are the enemy, especially w/ hard lines. They have a limited service life. Picked up the replacement line at Autozone. I figure I'll get a good five years out of the hoses before I'll even have to think about them. I suspect you could get some ss braided lines, but the cost would outweigh the usefullness. My 2 pennies.

Just to add to this, I couldn't find any of that hard stuff locally either. I got some from the wrecking yard, but since many of the factory lines are "formed", used ones don't work very well. I tried forming them with heat, but that just weakens them anymore.

I would imagine, if you can get it, that rubber fuel line, especially high pressure stuff, would last longer than vacuum line.

At Napa we sell, these red silicon vacuum hoses. They cost about twice as much, but that is not saying much b/c they are still pretty cheap. They seem thicker and don't get as soft after I have been romping ont he BBC for a wile when they are nice and hot. Thus far, I ahve replaced about 1/2 of my vacuum hoses with thise silicon stuff..

I also put wire loom over the stuff that lays on the engine (like my VRFPR line, charcoal cansiter, etc.)

A friend of mine re-did his entire vacuum system with the silicone hose that the ricers love so much. Not only does it look good (I know, that's not important...), it cured a hesitation/stumble problem he had been chasing for months.

I'm gonna see about picking that stuff up this evening and doing it. I knew there had to be something that was a step above just rubber or hard.

Thanks guys.
