They sell hard plastic line at most parts stores now, in the HELP! section with the rest of the vacuum fittings. Most places have it near the bottom of their display, and it's not too expensive. The b!tch is forming the stuff to the shape or routing you need. I've not had the time to test it, but I believe a little heat might allow you to bend 'er into the correct shape. I should email Motormite/Dorman about that...

Vacuum lines

Buster51,

Use 3/16" vacuum line. I replaced every single one of those hard plastic ones on my '93 BKO and it even cleared a bad vacuum condition with the EGR. :thumbup

Later,

Rubber will colapse
How many decades will that take?

I'v been running rubber vacume lines for about 10 yrs.

Do I really need to switch back to hard lines?

I was thinking the same thing. I have changed lots of the hard plastic line, but all the rubber stuff is original. Out of all my vehicle's, I've only ad to change rubber lines due to them getting burnt.

most part store, 3ft for 2-4 dollars. you'll have to cut the ends of to remove the cups, then reflang them. use ruber line(still have too) to contect to vacuum parts. i only used 1" per hook-up.
use the holdown clamp for 12-18 gauge wire w/rubber gorments to hold them in place.

i have only done this where my lines run ontop of passager side exhuast to the vacuum can. looks like crap for now, soon im doing all of it

Rubber lines collapse in long runs under low pressure (high vacuum), which is why Ford and most other manufacturers went to plastic lines. They're cheap to make, and form easily. Plus with the polymer they're made from, you can color code the lines for easier assembly line installation.

Steel lines are probably a great idea. Stainless would be the $hit.

Again, how long does this take?

The only hard plastic line that has been on my Bronco for the las 10yrs is the red one for the FPR.

Do I really need to switch back, or atleast replace my curent hoses with new ones?

A collapsed hose would couse one of those damn hard to find symptoms.

Ofcourse I'll need to actualy install the engine first :toothless

There's a hellava serach for us all!

Any hard vacuum lines that you find in most auto parts stores only comes in BLACK from what I have seen and come across. I'm not sure why the aftermarket manufacturers only make the hard line in black, bt maybe it has to do with cost of production, etc.

Anytime I've come across a broken hard vacuum line, I've just bridged the "gap" or break with a small piece or length of rubber hose and it always fixes the problem.

I didn't know the hard plastic was available in auto stores, I guess I've been lucky so far haven't needed yet. Even all black would do if you just color code it yourself. I was thinking that maybe there was a performance company that made all these lines already molded etc, I guess that's a bit of stretch. Great Idea to start a company and make them!

How many Bronco's out there in the world, not including this site?

Do you mean the rubber vacuum lines in different sizes to replace the hard plastic ones. Somewhere above it mentions collapsing? Anybody using rubber have that problem. I always worry about vacuum leaks. Let me know.

Thanks!
