Loose vacuum hoses

[aludden]

I just got Hervey's silicone hose set, but the hoses all feel kind of loose. Have you installed them and had the same problem? Do I need to put tie-wraps or clamps on them?
Thanks!

How loose are we talking? Like they just pull right off? I have his hoses, and I've had them for four years without issue.

+1. I got them recently and they felt like they'd never come off. As I recall, the hoses are several different diameters, both inside and outside. Are you sure you're putting them in the right places?

Installed a few sets and never noticed at excessive looseness.

That is strange. Yes, they are loose to the point of popping out if you touch them much.
I followed the numbers map on his website:

plus they are different lengths and they are all going in place. I also tried them in one direction or the other.

The old ones were tight. The new ones do fit, and look like they may not leak, but you can easily turn them and #5 and #6 have popped out when moving things around.

I'll keep looking to see what's up. We did put little tie-wraps on the Thermal Control Valve before putting the intake back in, to make sure those don't come out (although the heat might melt them?).

Thanks!

(although the heat might melt them?).

I wouldnt worry about that.

Talking about vacuum, the charcoal canister has 3 hoses going into it, and then one empty fitting. Looking at the parts diagram it mentions it should have a "101112 Cap, Blanking". Mine is just open. Is this a vacuum leak? Should I just cap it with a hose or something?

That's a really good question. Will be curious to hear from someone else, as I think I had an open fitting there as well. Don't remember 100% but will check when I get home.

It should be caped but it made no difference in any engine operation on my car.

I guess it may be capped so gasoline fumes don't leak out.
