Angry Silicone intake connectors

Help ! <img border="0" alt="[grrrrrrr]" title="" src="graemlins/cussing.gif" />
I am in the process of reassembling my 86.5 and I'm using the "silicone connectors" as some others here have done. My problem is that as soon as I start to snug the clamps down the plenii (sp) keep walking out of the couplings!!!!
I even went as far as getting them all connected "loosely" put a wrachet strap around the entire assembly sinched it up tight and then snug the clamps down. It dosn't matter how tight or loose I put them they still walk right off.
Did anyone else have this problem ???
BTW everything lines up perfect it is not a misalignment problem.

Thanks in advance for any and all input

What type of hose are you using?

If I understand the problem correctly, it seems that the clamps on the connectors are spreading their force over too wide an area causing them not to "grab". It seems that some focal point for the force such as a piece of thin plastic wrapped around the tube inside the connector. or under the clamps might focus the force where you want it.

John,
They are the silicone "turbo hose" connectors. They are nylon reinforced high temp connectors just like Berine and several others here have used.
The biggest problem is on the 85/86 intakes there is not much surface for the connector to slide on to (3/4" max).
I am thinking about trying hair spray on the like you do when installing handle bar grips on a motorcycle.

Ernest,
That does make sense due to the fact that the factory clamps are alot thinner than the ones I am trying to use.

Tim,

I had the same problem with my '86. The damn things kept sliding off into the gap between the plenums. I took some abrasive cloth and roughed up the surface area where the boots sit and and the inner surface of the boot, reassembled and haven't had any problems since. My intake needs to be repainted/powdercoated so I wasn't to worried about taking the abrasive cloth to them. If you don't want to do that then maybe just rough up the surface area inside the boots and try that.

Shane,
That makes sense as well, since the powdercoating is slicker than the original casting/paint that was on it.
I am kind of at a disadvantage right now since I had 7 stitches put in my index finger friday (dumb move don't ask), I just can't seem to get a good grip on them so I got pissed off and left them laying, I think I will give it a try again later.
Thanks
Tim

Thanks for the ideas guys.

I used a piece of scotchbrite on the ends and they went right on and STAYED ON.
No matter how tight the clamps are now, they don't push off.
After 6 months of being apart she came right to life and is running better than ever. Not suprised considering all the bad vacuum lines and all the other stuff I replaced.
I will post some new pic's soon
Thanks again
Tim

I was a late bloomer on helping for this one.
Just in case it comes in handy Tim.

If you went our route with hump hoses on the central t-tube, chances are that the driverside hump hose needs to be cut back some.
Bryan pushed his hump hose over the stop on the t-tube but I opted to cut the hose back until everything lined up properly without clamping.
The hump hose is what is causing your runner to "purge" itself off of the intake tubes.

If you find after a few days that the runner is still pushing off, you can either push the hose over the stop on the central t-tube or do what I did and cut it back until you can place the runner on the tubes without clamping.

I was jamming the runner on like you and torquing the hell out of the clamps, but nothing worked. The hoses are too slick.

You may have fixed it by Scotch Brite'ng the ends of the tubes but soething tells me that they are going to push off eventually.

In case it does, theres your fix......
