I am just about finished with the vacuum hose job but their are a few hoses 2 to be exact that I am unable to ziptie. I changed all hoses in the car and siptied them all.

Will they blow off or come loose if I dont zip them down. The stock ones dont have any kind of tie downs. The heat just makes them stick over time. I know the new hoses are a different material but will they stick as well when they heat up?

I would hate to leave them and find out later thta since I didnt zip them down they blew off. That would really suck.

 

Hoses that see vacuum all the time CAN'T blow off, but they can slip off if they are under tension. Pressure hoses CAN blow off, and should be secured. Trace the circuits and see which ones carry pressure. Zip tie those connections, including ones that tie into the intake manifold.

 

I remember reading in an old car mag that XS used to ziptie AND put a dab of superglue to keep them in place. I don't know if they still do, or even if it'll eat into the silicone or not, but it's a thought....

 

None of my vacuum lines are zip tied. I started to do it, but it wsa a pain in the ***, and most of them have smooth necks, so the zip tie wouldn't do much anyways. I used the orange tubed 3m weatherstrip adhesive instead, and so far no problems, knock on wood.
