How is everyone repairing broken plastic vacuum lines?
What is everyone doing to repair the plastic vacuum lines?
I was going to replace with rubber lines. But would have to come up with some type of connectors.
This will be on my 89 shelby dakota but after it is back on the road I plan on working on my basket case 85 onmi glh-t.

using a vacuum block with silicone hoses while trying to keep it look cleanish.

Buying from here for cheap and just replacing them as needed. you'll need 5/32(4mm) and 1/4" to replace all the factory nylon lines.

If they have just cracked at one place and is part of a "bundle' so it will remain straight, I have used heat shrink tubing. Cut an appropriate length, wipe any oil or grease off the broken ends, slide the heat shrink over the end of one piece, mate them, center the heat shrink and use a heat gun to complete the repair. It is almost invisible if you use black heat shrink.

I assume you used the heatshrink with the the glue on the inside to help the seal. It goes by various names

You used to be able to buy new plastic at parts stores.

You can buy various sized vacuum line from McMaster Carr. Use a heat gun to shape as needed. Bought a size just a tad larger than the standard size (I think 1/8 ID) and re-ran my stuff to the collector on the intake. Used silicone and heat shrink tubing to keep things in place. So far so good about two years later.

buy this buy that or scrounge exactly the right thing
hummm...
80's jeep trucks came with a few different motors
whatever the "right" one is/was when I found it , it had hard-ish vacuum lines like our mopar ones , but slightly softer and still flexible on an old used up truck ( early 90's)
to boot , if you've ever had an early log motor you've probably noted the coloured ink dabs on your vacuum solenoids ...
the jeep truck had the same yellow, white, blue and green vacuum lines , in the EXACT same colours
as a huge bonus it even had right angled and straight boot-ie ends for each line exactly the same as our mopar ones.. in matching colours
another great scrapyard discovery was in the late 80's early 90's mazdas
you want to remember to look under mazda hoods for the vacuum solenoid vent cap/covers
- to replace our blown away to dust foam block ones
the mazda vent looks like a little black rubber mushroom
it is two pieces a top , round cap and a lower section that fits on the solenoid nipple
inside is a removable, cleanable , replaceable piece of foam
same sort of foam our little exposed block style solenoid filters were made of
- these mopar SHOULD have used ... and they're also pretty much garden hose proof when rinsing out things

Air Line from air bags, like at truck parts places....work great.
