Vacuum lines blowing off....

Anyone else have this problem? My vacuum line sblow off form time to time,especially when they start getting softened from oil and heat. I know the zip ties work o.k., but what I would really like to do is replace the straight metal nipples with barbed ones. I think it is silly that Saab out these in with no barbs on them. What do you guys think? Anyone replaced or modded them somehow to make the hoses stay on better?

Use all silicone hoses with zip ties.

Look under mcroley's hood, then none of your vacuum lies will ever fall off again.

I replaced all of mine with silicone. It's a much stickier material, so it stays on better. I also zip tied mine too, just to be safe.

I zip tied mine on, they don't seem to slip off with the ties, however with 25+ psi I found a few places that I forgot zip ties

Something else to consider is the size of the line. Lots of places that sell svh by the foot will sell you the 4mm stuff which really is too big. Get some quality 3.5mm (hosetechniques, hightempsilicone, forge, etc).

I like the hose clamp idea as well. I used them on the bilge drains on my pwc in place of the oem zip ties.

I use 3.5mm silicone lines with spring clamps (the kind you hold open with needle nose pliers) on all the throttle body fittings...the tee (at the MAP) for my boost gauge is barbed and that blew off one day...so now that's clamped too.

Spring clamps look cleaner than zip ties IMO, and the are reuseable, and they don't increase your likelihood of having to replace the hose if you need to cut the zip tie off for any reason (I've sliced a few hoses in this way).

Very good suggestions here, zip ties look shitty.

We run the 4mm stuff on all the cars with no problems. One tip is to make sure the fitting is clean before installing the new hose. A quick blast with brake cleaner and it is degreased. Let it dry before fitting the hose.

Cool guys thanks for the help. I am using 4 mm hose and it's usually o.k. but when it starts getting old it has a tendency to blow off some times.I end up running out of zip ties sometimes if I've had the vacuum hoses off for one reason or another.
I really think they should have put barbs on those fittings.
I really like the idea of the spring clups vs. zip ties. Where can I get some of those that are small enough?
Thanks!

Actually a trick I learned from the chemist at work is that if you put a little drop of acetone and probably brake clean too and then put the silicone line on the nipple, it will actually fuse to the nipple... It will not come back off until you cut it off! You will probably have to cut it off, but it works great and once I switched to silicone lines and tried the acetone trick, I have not had any lines pop off and I have boosted 33psi + on occasion...

I think any auto parts store would have them. I got a package of 6 or something awhile back for another project for a couple bucks.

Something else to consider about the hose is that you get the real deal, not the cheap autozone/pepboys junk. The stuff you get from hosetechniques, hightempsilicone (HTS) or Forge is a bit more expensive...but you get what you pay for.

What I did to hide the ugliness of the zip ties...use smaller colored ones
